This guy has sensible intelligence to mobility scooter knowledge easy to understand 5/5 anything you need know about Scooter this guy to ask.
Thankyou Tom! My partner got no sense out of her supplier when her scooter came to a halt after two years light use.
"New charger and new battery - £800" was all they knew to say. She was in tears.
Nobody, but nobody, could suggest a way to check whether it was battery or charger failure or both. They were clueless as to whether the particular charger had to sense voltage before it could work (thank you for that tip) nor did they know there could be issues around having opted at purchase for lithium instead of lead acid. Read the manual? Haha!
My partner and I are heading off now to your Nithsdale Wheelchairs website where I feel sure we shall feel safe!
This Video was extremely helpful in figuring out a test process to avoid un-necessary parts/equipment purchases. Thank you very much! Manny Stockton California USA
Very helpful for understanding how some chargers differ. Thankyou very much.
I have a Victory LX sport on the way great info thank you 👍🏾
We really like your videos, you are helping all comunity , my english is not so good but just want to say you are doing a Great Job , I Will continué learning from you. bless for
You and we hope to continúe see more videos
Yes Tom, has the other subscriber said very helpful video, and I will also get one of the clamp testers, learned a lot from that vid Tom cheers, 👍👍👍👍👍👍👍👍.
I never knew this much about battery charged that was fascinating
Superb video, well done. Thank you
Great stuff thank you!
Fantastic video
I appreciate your video great video tks
Great video
Brilliant thank you ' 😊👍
Legend!
Excellent video. When you tested the voltage on each battery individually, you had 11.5v and 12.5 volts. Why do you think this is and what effects do you think this will cause in the future, if anything?
Battery will not be in as 100% condition so a little weaker than the other one. Through time you will need to replace both of them.
Hi .
Yes interesting video . Thanks
Question please .
Just fitted new fully charged batteries to my scooter .
But on the monitor the last three lights don’t light up .
Any advice please as to the problem.
Is it a faulty monitor.
Or faulty battery charger ?
Thanks
Top job Tom you can’t buy experience? Many thanks.
Is there a way of knowing if a 24v reverse polarity charger is working? Also how would you know if the charger is reverse polarity?
Good info I have a Golden Avenger that comes on but no power to the Motor?
Very difficult to say what’s up my friend there’s a lot to check any flash codes ?
Thank you for all these valuable videos, but some things are beyond a user. This particular, and your similar videos are helpful. Could you advise on a scooter,shop rider, why the battery power shows it is falling within a few minutes, and the scooter slows down to an almost stop position.Would the speed control have any reason to cause this.? I mention this because when I turned the control knob at one point the scooter faltered.Any thoughts.?
I have this problem, shows fully charged, I’m a new scooter user , bought second hand, start of snail pace , stopped and put it up a little, little blue light starts flashing and scooter starts beeping, speed went very slow barley moving, but thankfully got home. I’m scared to go out on it again in case it stops and I’m stranded.
Thanks Tom, that was very informative. The tester you plugged the charger in has that got a name, what type of tester is it called. I will get a clamp tester now I know how to use. Thank you again.
clive harmsworth I will check the name Of the tester mind you it was over a couple hundred £ years ago don’t think they make them any more will most likely have a new model out.
Hi thanks for the information I have an old Mercury M48 I charge it over night some times it does not charge so I unplug the charger from the scooter and the mains replug it back in it may work then or not were should I be checking I have all the test equipment I need. Thanks in antisipation Bigt
I would check to see if you have a slack connection between the charging plug and the female plus. also check the fuse at the rear of the scooter for corrosion or slack connections.
very helpful thank you my opticharge 8 amp charger wull not charge up my batteries on my invacare orion metro
mobility scooter and i am still trying to fix this
Recon the 2 inside lights are flashing on the charger eh. If thats the case check to ensure you have enough voltage at the charger socket also that you have a good connection at all terminals from the socket to the batteries
can you use a motor cyle charger if i charge each battery separately
I just come across your videos.
I too am a mobility scooter technician. I am finding your tutorials quite informative.
Can you please tell us what make and model the blue battery tester is that you use in your video? I"ve never seen one like it.
Keep up the good work.
Joe
Hi, i have has this for years now and cant really remember where i purchased it. Must be around 20 years now...but i would recon it could by made with a current metre or just use a DC clamp meter on a home made extension wire.....
@@tomjacques4 Thank you for responding. You're probably right, but, yours looks like a really good addition and also neat. What is the make a model number of your unit?
Be Safe! Keep up the great work that you are doing!
Hi hoping you can help I have a go go pride ultra scooter and am having trouble . I can put brand new batteries in and it will run fine until I have to charge it what happens is the needle will read it has a full charge but when I go to ride it the needle goes way down instantly almost and I have very little power. I have bought new batteries a few times thinking I got bad ones but the same thing keeps happening can you tell me what I need to check please. Thank you
I find the fault of my scooter not charging is the fuse for the battery has blown. Where can I find a red fuse for a Pride Victory 10 four wheel model
Hi fuse is on the tiller together with the light fuses and ignition.
I'm new to the mobility scooter world and already I'm suffering from range anxiety. Batteries are 1 month old, I charge them up after each time I go out (usually only travel 3 miles maximum) overnight and the battery charger takes approx 14 hours to fully charge the batteries (it's as bad as waiting for paint to dry 🤣), but when I go out on my scooter by the time I've travelled about 1.5 mile, battery indicator light has dropped by 3 lights, but if I turn the scooter off and on again, the battery indicator shows only 1 light dropped. By the time I get home again (travel 2 - 3 miles maximum) 3 lights have dropped on the battery indicator on the scooter.......I only ever travel at the 2mph half speed . I also loose power even when travelling on the level, but if I stop turn the scooter off and on again, the scooter will travel at the ok speed for a while, then the speed drops again. I don't know if it's the batteries that are at fault, the charger or whether there is a problem with the scooter itself. I have a Pride Apex Rapid with 2 x 18ah batteries and I'm supposed to be able to travel a maximum of 16 miles depending on conditions. Any suggestions on what I ought to check to see what's wrong?
Mine does that too, did you find the solution /problem ?
@Bluelady777 I had a faulty charger......not had a problem since it was replaced under warranty.
Thanks for the video: I fitted two new 75ah gel batteries in my Wife's Pride S4 scooter in April, so not cheap but thought we would be good for at least a couple of years, the AGM,s that were in before lasted 18 months.
She uses it most days for 2 or 3 miles, and she plugs it on charge with a Powerfirst PF2408LP intelligent charger at the end of every day. Back in April things were great she could run everywhere around the town and hardly drop a bar, now here we are in October and after two miles its flashing on 2 bars and barely managing to get back.
What do you think might have caused this? Do you think the charger might be delivering the wrong charging profile?
As long as you are charging ever night and the charger states it fully charged then it should be unless there is an issue with the batteries. Gells should last around 4-8 Years. I would contact your supplier if it’s still under warranty.
Hello, I had the same problem with the gel batteries, they lasted 1 year before they were defective, I am currently driving AGM batteries, these have been in my mobile phone for 2 years without any problems, I live in the mountains and therefore always need 100% power, I I recently saw a video and it was said that it's best if the batteries are fully charged before each trip, no matter how far you've driven the mobile before, a maximum of 8 hours and I disconnect the mobile from the charger before I drive!
hi enjoying your videos but I wonder if you could help me I've been looking for some rear wheel assembly for my wife's breeze midi 4 could you suggest something cheers keep up the videos
Hi! I have a jazzy elite 14. My question is, is it normal for my charger box to get really warm. But not to warm to touch. Just really warm after 2 hours of charging give'er take.
If the batteries are in poor condition then the charger may put more current into it hence warm up. Some
Have fans etc to keep them cool. Should really cool down the longer they charge as the current decreases.
I have a 3 wheel scooter that has started popping the breaker and stops running going up incline. Could that be caused by weak batteries? I tested both batteries and tested 13.4 If not where should I start trouble shooting ?
Check for slack connections and the Motor could be a faulty circuit breaker
they are standard XLR connectors... you charge £20-30 for them... they are a couple of quid from any electronics store like R S .
Hi Cole I can’t find it on our site. Our plastic ones are a 10er and the male charging sockets also the more expensive ones (female charging sockets) are pre wired around 20-25 and come straight from the scooter manufacturers, plug and play. We recommend getting the correct connections so they make a proper contact this will prevent heat buildup in case 2 different connections are not matched.
Hi I have a question please me and my partner both have a scooter both are freerider brand with 50AH lead acid batteries on we keep them out side at the back of the house which has been fine for the summer as we have only had them since April this year my concern is the winter is coming lower night time temperature frost and freezing ect the scooters will be in these temperatures I can house them in a shed to keep the weather out and have fitted outdoor weather proof plug sockets so we can charge them outside obviously keeping the charger away from any rain or water but I am not sure what to do to avoid any damage to the batteries we will still be using the scooters during the winter and charging them what would be the best way to protect the batteries ? I had thought about removing them from the scooters on colder nights and bringing them indoors but then I cannot charge them away from the scooter or if the charger is plugged in and connected to the batteries on the scooter will the charging be enough to stop the batteries from freezing and getting damaged I assume while charging some heat is created in the batteries is this enough many thanks .
Billy Hood correct as long as you charge them during the night you should be ok. A good quality waterproof cover is a must, no silly cheap £25 cover. No plastic either. You must let the scooter breath otherwise condensation will occur and will start rusting etc. Hope that helps
Hi big yin, do you service mobility scooters? I think it needs reprogrammed for speed. I live in Blantyre G72 0AZ
Hi billy yes we can help you out best contact us to arrange a visit office number is 0141 4470 172
Hi my scooter only has1 battery, the battery is pretty new but I wanted to see how far it would take me before a trip away, it went ok but ever since is not charging fully, charger says it is and stops charging but as soon as you start moving it its dropping 1 bar ive cleaned connectors and it seems fast enough but its a worry
Make and model ?
Hi .
I have a jazzy 6,
It has 2 12v 34amp batteries. The jazzy is to heavy so it stays in the car I bring the batteries in to the house, as they are 12v each can I use a smart car charger and charger separately. Thanks Jim
Maybe better get a hoist. Or a long 13amp
Extension lead
Every time I charge my scooter I plug in the charger the battery is fully charged all the lights are working but then I go to drive it and it starts to beep nine times the last few times I had to take the scooter completely apart and put everything back together and then it works again I don't get it I don't know what to do but it stopped again because I had to charge it. Is there an answer for this old lady because it's exhausting it's really heavy to lift the seat and then take the rear end off and then put it all back together
Sounds like a bad connection check all contacts ps what’s the make and model
I put push to test volt meters on my scooter they work well as you can see what is happening at any time with out taking the scooter apart one on each battery and one on the charge socket they are so cheap now you can see what is happening any time
Hi yes good one . you could do that but does not work on all products as some are fitted with a diode.
Dont know if you read this but where do you get that inline easy checker ?
Got that 15 years ago sadly no longer available
Hi Tom, very informative videos. I never realised there was so much involved with electric mobility scooters
My friend has a problem with his 8 amp 3 stage charger. (It looks very similar to the blue one in your video at 24 mins approx.)
The three leds are flashing when you connect it up. The sequence is low battery lrd flashes once then all three leds flash together. This constantly repeats. Also a relay can be heard opening and closing in the unit.
Is this a problem with the charger or with the batteries being flat on the scooter? ( It has been idle for some time)
Cheers
Trevor
Hi 👋 check batteries get them tested also check all cables to the charging socket and ensure you have power at the socket
Hi Tom,
Back about the same problem. His supplier brought 2 brand new batteries but charger behaving as before. This is the first time I was able to check the bike out. I noticed that the charger connection had a lot of slack movement. I had to remove the fairing, headlight etc yo get access. When I eventually got the charging socket free from the bike the cable was not a short one, like in your video, instead the cable disappeared into one of the frame legs and went right back to the control box! I imagine the fix is to cut the cable up near the handlebars and solder on a replacement with the short lead. Is this recommended.? I didn't want to start cutting cables if this was not the approved method.
Akso noticed when I switched the ignition on the display eas reading 24volts. ( I thought this was full charge but after watching your video I'm not sure. Anyway, I was able to drive the scooter but noticed the voltage dropped very quickly and after about 200 or 300 yards the audible low battery indicator started sounding.
I'm more confused than ever. If the batteries weren't charging, how was the scooter able to drive at all. And why did it rjn out so quickly if the onboard voltmeter was showjng 24 volts. Sorry to be so long winded but I would like to get to the bottom of this
Cheers
Trevor
I have a Sterling S425...it hasn't been used much in recent months, I ran the battery level down to the orange but when I plug the charger in it goes red.... yellow (solid) charging...then green (fully charged) after only a few minutes....is that a fault?...can't see it being charged that quick or can the batteries still be fully charged?
Hi always charge a minimum of 8 Hrs even if the green light comes on earlier. It will go on a trickle charge after that.
so my charger is the 5 amp hp8204b battery charger and the power light comes on but the charging status light doesnt! no orange or green light only the power light. my batteries are not flat in fact the 80% full. so idk i reckon my charger is broken. it does have a fuse which looks ok.
So you have watched the video and hope you have power at the charging socket if the scooter yes?
@@tomjacques4 YES - well my batteries are at 80% at least nearly full. So I know it is not my batteries that are flat. I guess tomorrow I will put my multimeter into the charging socket and check that out. But I am 99% sure it will be my charger.
Your video was helpful trying to figure out the status of batteries on a used scooter we bought - I'm not good with electrical issues. I have two questions you may be able to help with. I'm going to replace my batteries. I currently have two 12v 18aH batteries. Can I upgrade to two 12v 22Ah batteries (same physical size) to increase my range? I assume I need to buy a new charger if I get highter AH batteries.
If you advise against increasing size, do you see a problem with the power supply that came with our scooter? It says GEL battery charger (Model P1202B, DC output +24v 1.8A. THe old batteries are SLA and I intend to replace them with SLA's regardless of the amp hours.
I don't think it matters, but just in case, I have a GoldenTechnologiesi LiteRIder 3-wheel scooter, model GL110. I don't know the age of the scooter. I don't have the manual. The only Serial Number I can find is near the back wheel axel - GLC0006. Thank you for any advise you can offer.
Yes you can fit the 22s charger should be the same as the battery. 1.8amp o will just take longer to charge
Thanks so much for your reply!

Hi, I have been given a Komfi - Rider mobility scooter, when I plugged the charger in to charge batteries the red light on the charger is flickering rapidly and is advised as incorrect, do you have any idea why this is, also the key I had for my shop rider scooter does not fit ok in the ignition, do you stock keys for the ignition got this type of scooter .🤔😊
If the charging fuse on the scooter had blown. Would you still get 24v on the scooter charging plug?
sorry no
I have a Sterling Sapphire 2. It has only been used aprox 8 times and then left to stand for 3 years. I put the charger on and it keeps blowing the 3amp fast blow fuse in the charger. Any ideas ?
Recon you will need new batteries
Could also be a charger issue. Check the battery terminal connection on the battery box. Hope this helps
I took the batteries out of the black boxes and tried to charge them with a normal battery charger... neither battery will hold a charge so new batteries it us then 👍👍
I have a Colt Executive scooter with 100amp batteries. I charge up it shows fully charged. But it drops to show almost empty after a few miles. It’s meant to do 20 miles. If you can provide any advice thanks.

Check to see if any part of the motor and brake are hot 🥵 if not Get batteries tested with discharge tester takes 1h plus to test each battery. That will then give you a computer print out of test. Do not use any cheap rest equipment that tells you in minutes if batteries are ok or not
@@tomjacques4 if they are hot what does that mean?
If battery charger Green light comes on soing charged do I still leave it on for 8 hours thank you
Hi my shoprider doesn’t charge I plug the charger in to the scooter the charger starts up (the fan) the lite flashes yellow then the charger completely turns off after 2 secs with no lights ,what do you suggest I test thanks
Check for voltage at the charging point of the scooter there must be voltage. And said voltage must be higher than 16v
Just curious as to why you didn't simply make a cable adaptor using that new female socket you installed wired to the plug off the dead charger? Would have avoided modifying the scooter and allowed a charger with either connector type to have been used in the future. Otherwise - good video.
Yep sure could of but don’t like too many joints more chances of overheating if they become slack. And those Anderson connectors are not the best. Mind you I’ve done it before but not with those connectors but with the 3 pin connectors for reverse polarity chargers. well spotted mate.
How to replace right steering bar on my sterling s700
Hi we can supply the track rod ends and to rod Assy if required. Easy job. Just undo the bolts holding the track rod end on and it will fall off.
I have an older model shoprider 3 wheeler, wondering about getting a replacement charger off ebay,
they tend to only have positive on pin1 and negative on pin2, nothing on pin3 the inhiibit wire.
I assume the batteries will still charge with these chargers but no inhibit function, can you just join the negative on pin2 to pin3 thus making pin3 negative also and making the ihibit function work?
Australia here, dont want to blow anything up.
One and 3 usually pos and beg. Inhibit is 2 if you check the charger it’s should be 1&3 usually this is standard

Hi Tom, I have a ZT500 mobility scooter bought in Nov 2020 from Green Power Ltd it's been working and charging fine until boxing day when I went and turned it on and it had no lights on the control panel it was completely dead, I plugged in my charger that came with the scooter and the green light came on but the Fan was not working telling me that the charger was not working properly, does your Company/Firm do you have a website I can send pics&specs of my charger, Thanks, Patrick Considine.
Sounds like a fuse has blown check them and there may be a circuit breaker on the scooter
can you tell me how i can load test my 75ah mobility batterys. not one video on youtube tells how to load test mobility batterys correctly. how do i know what the cold cranking number is. i have got i 6/12v load tester but its for batterys with cold cranking readings. And mobility batterys just dont have this number. i have tested my batterys with this load tester here,s what happened. i charged batterys fully i think they charged upto 26.3v. i then left then for a few hours and they settled permenently at 25.8v i did a load test on each individual 12v battery these were the results... starting charge on load tester was12.6v i load tested them for 10 seconds and they dropped to 11.4v and then recovered to 12.6v the needle pointer kept in the lower green zone through out the load test then recovered upto the top of the green zone. could you help in any way or maybe do a proper video on the subject. it appears no one else will do load tests on mobility batterys. could you use 75ah batts in the test if at all posible... love watching your vlogs my friend, they really are educating and intresting.

Hi need a special load tester that discharges over time depending on battery current. Expensive tool usually only dealer and engineer like us have them. You will need to take the batteries to a dealership, could take around 1hr or so to test one battery.
I have a Jazzy 1122 that will not work if the internal battery charger is installed. I purchased a new charger and it still doesen't work, but when I remove the charger then it drives... please help!
My charger MK is not charging its making clicking noises and lights are jumping , unit is overheating as well 😳😬
Is it the fan ?
Can you advise please thanks 🙏🏽
How old are the batteries. Is the scooter holding its charge ? Check how much current s the charger giving the batteries when flat and once fully charged
@@tomjacques4 the scooter still has charge left , I just went to top up .
What tool do I need to buy ? To test this . Batteries are 4 years old I think 🤔.
P.S. I have tried different chargers as well with the same re sults

Sounds like there’s an issue eh. What checks have you done. What happens when the battery level is low. Are these eBay batteries or proper ones

Hi. My scooter is charged over night. So I full charge the next day. I have power. But hardly any speed. What can it be. Thanks karl
could be wrong but might be throttle pot, Tom will know though
Good Morning Karl: there are a few reasons that could influence the speed and this will depend on the scooter your have. 1. the throttle pot 2. the speed pot 3. Half speed switch 4. some (8mph) may have a micro switch on the tiller to slow down the speed on corners 5. slack or faulty wiring 6. a worn or broken brush unit (depending if your motor is fitting with 4 brushes) 7. An electric brake problem. 8. controller issue..... So as you can see there will be a lot to check ....
I HAVE A PRIDE TRAVELLER PLUS SCOOTER...MY CAR HAS A BUILT IN 150 WATT CONVERTER, CAN I USE THIS SYSTEM TO RECHARGE MY SCOOTER BATTERIES???
Could do mind you we sell chargers that you can plug into the cigarette socket but it’s always best to charge the batteries for a minimum of 8 hrs every time you put them in charge so if you are doing it your way then only as an emergency 🆘 and not recommended for every day charging. Hope this helps

@@howardkahn4330 ok then as
Long as it’s a true sin wave inverter then fine and again minimum charge 8hrs calculate that the battery is big enough to accomplish this
The gel batteries don't convince me at all, I live on the mountain and I'm not allowed to use public transport with my mobile (it's not safe) I have to use my mobile to go to the doctor, go shopping, etc. even in winter, I take care of myself and I don't have any help AGM batteries are the best they keep the voltage even if 1/4 of the energy has been used, but it is also clear that in winter at minus degrees the energy is used up faster and they are a bit more expensive to buy but they last longer than the gel batteries . I have no problems with AGM batteries.
