- In todays video I introduce and review the Schumacher SC1281 Battery Charger/Booster/Jumper. If you have any machine that runs on a big battery, you owe it to yourself to have a durable, quality battery charger in your garage or shop. This one is small enough to put on a shelf, yet powerful enough to handle all you battery charging needs. At $75 it really is a no-brainer. Stop buying batteries when it may just need to be charged.

Astonishing the amount of people reviewing this charger who have no idea how to actually operate it.
Thank you very much for this video, it helped me very much. The language was very clear.
Very good video! Keep making content! 😎👍
I just picked this up, so I appreciate the great review/tutorial. Thanks.
@5:20 this charger has a "bad battery" indicator (the bottom one on the right), why didn't that come on?
It doesn’t check that in the charging mode only in the jump modes that’s why. If he ran it in the boost or jump mode it will light up bad battery.
I have an old Schumacher charger from the 90's. It still works fine but not sure how long. I'm seriously considering buying this bad boy ☺
I bought a Schumacher SC1281 Battery Charger, earlier today. It's charging my husband's van battery. Thank you for the video.
I just purchased from Amazon....thank you for this video. It came today and I hooked it up to my Escape (dead battery due to not being driven because of this virus) My battery is only 18 months old...ugh. Lost my husband 2 years ago, don't want to constantly bother my son every time I have a problem, so I'm learning! Thank You....I was a bit nervous and this video certainly helped :-)
I'm glad you found it useful. It's probably the best and easiest charger I've ever owned, and I've had a few in my days. You will easily be able to charge your battery and impress your son. I have an Escape also. Don't you love it?
@@jasonfixedit4100 I do, and I have an F-150 as well.... 👍🏻🙂
responsible for a neighbors car...drove it weekly and then the battery was dead. Neighbor had more serious issues to deal with. Purchased this on Amazon, hooked it up and several hours later, battery charged and working fine. I didn't test the jump start ability because I didn't need to, but impressed with how easy to hook up and monitor the charging. Thanks for doing this.
I'm getting ready to order one of these chargers too.
On a different note. i tell all my friends about the milwaukee tire inflator from home depot. It is so convenient for adding air to your tires. Happy Holidays!!😁
Great video thanks for sharing.🙏
Great Video!
The connection error indicator feature was designed with women in mind, particularly those who are likely to encounter a serial killer or get caught in a blizzard. Mr. Shumacker told me himself
Good info on the video....I'm getting me one on Amazon right now...We are staying at home because of the virus but now my car has a dead battery so we are really stuck
Thanks for the comment. You will really like this charger. Smart chargers are the way to go these days. A lot better than the old "buzz box". Good luck and stay well.
@@jasonfixedit4100 I remember the old dumb chargers, if you didn't check them with a voltmeter you could easily overcharge the battery. Good video!! 👍
Thank you very much for video
Your welcome. Thank you for your support
I just got mines, it did the same thing on a battery that was on 7.6 volts, since the bad battery light dint go on I left it it went on and off it keeped doing that till it brought up the percentage to 12, after that it was strait charging, the battery is now at 12.6 and it says 85%, and is still charging it, this was a battery that we had ready to throw out, it saved it, I say 85% as of now it's pretty good
My charger does the same thing even on new batteries. I just leave it sit there. It will cycle between on and off for a while then it charges the battery. I primarily use it for my trolling motor batteries which I drain down pretty low before I charge them
This is an important point. The charger has AI and a desulfating mode which attempts to revitalize a dead battery. Don't jump to conclusions. It may be able to revive a 'dead' battery if left on for a period of time. Read your instructions!
You did not follow the directions. The charger should not be plugged into the wall socket until AFTER you connect the cables to the battery. You plugged it into the wall socket BEFORE you connected the cables. Once plugged into the wall socket, if you don't hit the Start/Stop button within 30 seconds , the charger will turn itself on automatically. So by the time you attached the cables to the battery, the charger was already "On" and the charger was reading the correct (low) voltage. Then you hit the Start/Stop button which turned the charger "Off". When you turned it back "ON" , the LED read zero, you assumed the battery was BAD. But when you started to take off the first cable, the LED read 10.2. Why? Because when you touched the cable, it re-established good contact with the post and the charger was working again. Had you simply re-attached both cables, the charger would have gone to work on the battery.
And yes, as another commenter noted: when charging a battery outside of the vehicle (not hooked up under the hood), special precautions should be taken. Again, you did not follow directions.
Where quality and price cross. Im about to buy one instead of the Harbor Freight Viking. Thanks and good video!
I have the same charger it also has an additional feature it’s the desulfation feature it can detect excess sulfate on a battery and start desulfation and it will continue for up to 10hrs to remove sulfate from battery 👍
I bought the same exact Schumacker battery charger shown here. According to its manual, it says before charging, you must connect a battery cable of at least 2 feet in length (to keep yourself as far away from the battery when connecting the battery to the charger) to the negative battery post of the dead battery and then connect the free end of the the battery cable to the negatvie battery clip of the charger then turn on the charger. I noticed on this video you did not do this, so is it safe to not connect a battery cable to the negative battery post of the dead battery in order to charge the battery? I'm just asking because these are the instructions on the manual; maybe it is just a precaution in case the battery explodes or ignites from fumes from the dead battery.
Very good and informative video, would have been Perfect if it gets to start charging so we could see how it process . thank you much !
Thanks for the comment. Yeah, that would have been good. But really, it's a smart charger, so nothing really to see. The display with switch back and forth from voltage to percentage about every 15 seconds. When it's done, the charging light goes out and it switches to "maintaining" untill you come back to disconnect it. It's a great charger.
Read the Amazon reviews for this model. Over 300 one star reviews for problems ranging from melting the cables, melting the charger, stopped working after 2-3 uses, and the main one, it charges at maximum 30 amps without tapering down or stopping. There are probably over 100 users that complained that it melted their new automotive or golf cart battery, and no one is able to get a response from the manufacturer. My first one wouldn't stop charging, the replacement one reads out totally erroneous numbers.Don't say I didn't warn you.
NOT buying based on this. Thanks for the warning 🙂
Lol, it's a great charger. People just don't know how to use tools and always think they know it all. Of course they will melt if you have it on boost for way too long while you're trying to start it at the same time. Instructions are for these 1 star reviewers.
@@rticul8862 Isn't it supposed to be a smart charger?
@Scott Bond it is, to an extent. "Smart chargers" have limits. Still using mine daily with no issues.
I have had two, first one quit all together after 6 months, second one comes on but wont register battery volts and when turn u it on it cuts right back off, i have had it 3 months
Great video! The model I've gotten is the sc1280. Yet this video has the sc1281. ? Curious though as I have an interstate battery 12a and have no idea what category it falls under for charging. I was told to do a slow charge. What's your opinion on the slow charge? Safer for longevity of a battery?
Yes. Ive heard that many people. The slow charge is better for the battery is what they tell me. If your battery is just a normal car battery, choose the normal mode. Its not AGM.
Thank you! I trust your sound opinion.
The battery might be good. How? Smart chargers will not start to charge a battery if it is to low. A regular charger will, and once you get the battery charging for awhile then the smart charger will work if it is a good battery. Just something that I found out about the smart chargers limits.
My experience exactly.
Does it have to be plugged in to use or is it a power bank too?
I just bought this charger also. My question is, with this charger can you precharge it first or do you have to plug into a cord always
Nope, this is just a charger
how do you know if you have an agm battery or something different? my diehard silver 34/78-4 doesn't say on the label
I just bought one and put it on my truck out of the box.
Can it work right away without changing?
If it reads extremely low, select boost and run it for 5 minutes, then switch to trickle it retest and will show 12 volts....that's the "smart chip" weakness, it detects too low a voltage to attempt a trickle charge.
If its bad SUL will light up.
I have this one and it cut off telling me my battery was bad. I put my old Schumacher on it and it charged it enough for my truck to start.
The problem with these microprocessor battery chargers is that if your battery is too dead it will not try to charge it. You could have a battery that's a week old that's dead in your car and if it drops below a certain voltage, it wont charge it. I found a way to trick it, if you have an old school battery charger, one that you can make spark if you touch the two clips together, hook that up and then hook one of these smart chargers up and run it for a minute and then you can unclip the old charger, then this one will keep charging it.
Schumacher says to use AGM mode when charging deep-cycle/marine batteries. That isn't in the manual, but they said it in an Amazon answer to a question.
It is in the manual, under what defines a standard battery. States standard battery's are not deep cycle battery's and under AGM it states deep-cycle.
How do you into de-sulphate mode?
Good video! Is here a creative way to make this battery portable somehow in my car?🤔
Its a battery charger drrrrrr . Not a portable battery powered booster
Could I charge a similar marine battery using this charger connected to a 1000W Pure Sine Wave power inverter hooked to a standard vehicle battery? Of course the vehicle would be running during the charge. My situation is I travel for work as an escort vehicle for oversize semi loads. Sometimes we sit at job sites waiting to unload for hours at a time. I'm planning on using the inverter and a stand alone marine battery to be able to run some small electronics in the back of the SUV (seats removed etc.) When the battery gets drained after a few hours, I'm wondering if I can charge it using the running vehicle, inverter and this charger here?
That sounds like that would work
that is a round about way of doing it, you could just connect the semi battery to the inverter battery. at least your not using solar as all this converting from 12vdc tp 120vac back to 12vdc wastes watts that would be given off as heat.
Is the schumacher battery charger attached to a wall socket itself?? Can you answer that question please, or does it store charge and you use that charge to charge the battery?
Plugs in wall
Can you jump start the battery? I just need it to quick start, not charge, so I can go drive to get a new battery. My current battery is completely dead.
Connect it to your battery, choose battery type, then change rate selector to "100A Engine Start" and press the start button. Then start your car. Or, do the 30A Boost for a fast charge (about an hour) then go get a new battery
Can you use this if your battery goes dead while you’re on the road? Or does it always have to be plugged in if you’re going to use it?
It's not a battery unit, so it needs to be plugged into a US outlet to work unfortunately.
I bought this charger 3mo ago and now it wont turn on at all...😞
can i use it for ecu programming sir , i mean while using autel maxisys car scanner for ecu programmig i need more than 12.6 v sometimes .
this device can be used as a voltage stabilizer ?
im waiting for your reply thanks
I have no idea. I doubt it's meant to be used as a power supply. Its a battery charger
As long as you have a car battery in the circuit it should be fine, but there are power supplies available to do this kind of work. I would think a purpose built supply would be much better.
My car has a 100amp battery. Can this bad boy charge it?
Does anyone know where the fuse is located?
Some battery chargers will not start to charge until it’s at a certain voltage.
Correct, thanks for bringing that up!
Yes, this is the reason why many people don't like "smart" chargers. Since the "bad battery" LED isn't lighting up, I can assume that this is the likely source of the issue. It's likely that he could have started a charge by using the engine start or boost modes, but it's uncertain if doing so would be able to revive a dead battery that had been drained to about 3.5 volts.
You need to hammer a beyond dead battery in manual mode first, use 30a boost on this charger, get it past 10.5 first. This charger has an actual 'dead battery' LED - not saying it's accurate. Always check and fill that battery up with distilled water before charging!!
Why does the cables get hot?
I just purchased this because out car has been having issues with the battery and can't get it into the shop until after the weekend... How do I charge the unit before using it??
Good question I'm trying to figure it out too
This is not a portable charging pack. This one need to be plugged in to use.
You don't charge the unit, you simply plug it in and that charges the battery.
@@0311cmc are you sure?
@@blessflomo2336 yes
Does it have to be plugged in to use ? I’m arguing with my mom about this right now lol it’s cold outside……In order to use this to jump my car do I have to plug it into something ?
Yes.
So you can't revive a battery with it? Like repair/desulfation mode?
No.
Yeah you can I just got mines in the mail. Charged and it desulfated a battery that was sitting for 3 years and fired the van right up
@@moistmuffinlover873 May I ask how did you do it? Did you start it on 30amp? What was the voltage of this battery before you charge it?
If it's a bad battery why didn't the "bad battery" light come on on the charger?
Now that I cant answer. A little while later after that I tested another battery and the bad battery light came on. But every tested that same battery in the video it did the same thing.
Hi! I just bought this to start my car. Does this need to be plugged in while charging and starting the car? If I need to start the alternator is the process the same?
No, it runs on the same magic gas you're huffing
@@Cacheola Your comment is highly unintelligent and shows your complete lack of understanding in the questions asked. Keep your negativity to yourself. It isn't tolerated here. Puff on that magic ass.
Have u found the answer ? Cause I’m stuck on the same boat
Smh damn I’m stuck too never got to use it jus brought it around the pandemic Lol smfh today I’m stuck
It doesn't do anything if it's not plugged in. There are some portable batteries for charging or starting--this is NOT one of those.
The bottom right indicator "BAD BATTERY" should have come on(?)
You'd think.
Any idea what the difference is between the models 1280 and 1281?
Schumacher SC1280 is smaller for smaller thing up to small cars and trucks
15A 6V/12V Fully Automatic Battery Charger and Maintainer for Motorcycle, Power Sport, Marine, and Automotive Batteries $46
Schumacher SC1281 is much stronger for everything up to 12 volt trucks and tractors
100 Amp 30 Amp 6V/12V Fully Automatic Smart Battery Charger 100A Engine Starter and 30A Boost Maintainer and Auto Desulfator Advanced Diagnostic Testing $80
@@goe1punk - Thanks alot, i was just about to buy the 81 but after reading your comment, i realize i really only need the 80. Thanks again. 👍
@@tambor76 Your very welcome
Both chargers will start most vehicles in average climates.
If you have a small 4 to 6 cylinder car or truck the SC1280 should be fine.
I was just watching videos on this because I just received the SC1281
and wanted to make sure I was running it correctly.
I have a 6 cylinder truck but wanted a charger with a strong 30amp start for COLD DAYS if I needed a jump on something.
Twice the price almost but every video I watched made it sound like the Schumacher charger was a good long lasting product if treated right.
Your Welcome again.
2 questions..... Do you have to have it plugged in socket? And 2nd whats the average apartment voltage rated at? Might be dumb questions but hell I don't know
Hi. Yes, it has to be plugged in. Bit I dont understand the second part of your question. Can you clarify?
IF YOU'RE FOOLISH ENOUGH TO CROSS CONNECT YOUR POSITIVE AND NEGATIVE SIDES OF YOUR BATTERY, THEN YOU SHOULD PROBABLY THINK TWICE ABOUT EVEN TRYING TO HOOK UP SOMETHING LIKE THIS!!!!
I'm pretty sure for charging you have to select 30 amp to charge. The selection you had it on is for trickle charge.
So I'm restoring car and have new battery. Got this to recharge while trying to get car started. Hooked up after battery died. Said 38% and charging. Ran for couple minutes and never changed %. Turned off unhooked, gave it a few seconds then hooked it back up. Jumped to 76%. Replaced it once because of this issue. It will show low % and not change. Then unhook and when i hook it back up it jumps rapidly. Anyone having similar problems?
Could be something called surface charge. Turning on your headlights for a few should discharge that.
When im charging i take the terminals off so its not tied into system
I got a brand new one and the cables get very hot. I see reviews of it catching on fire. the clamps are also very cheap and weak, so i dunno what your smokin. The case makes it seem high quality when its not. The bad battery light didnt even come on when you tried to charge it lol, how much you get paid to do this review?
What’s does 5ul mean or sul keeps coming up
SUL = it means "sulfated". Sometimes you can just keep charging and it will overcome that condition.
Does it mean is full? It says sul to all my car batteries
This is a good link that explains it.... www.google.com/amp/s/www.crownbattery.com/news/sulfation-and-battery-maintenance%3fhs_amp=true
Do I have to keep it plugged in to use it?
Yes, once the battery is charged unplug the charger and then remove the negative then the positive
@@lexbeltran1354 yes but does it have to be plugged in to use to jump start the car ?
@@Culley91 It has to be plugged in to do ANYTHING. It doesn't have a built-in battery. It's a CHARGER.
I have one and it is not simple to use
My battery charger is not working like this 888
just turning on and off doesn't tell me anything. If they call it a tester, it should give more info.
Didn’t really show how it works, or if it works.
2:08 12.6 lbs
Let's leave it on without shutting off the unit, not very safe.
The microprocessor board in this pile of crap is weak. Mine lasted a year and it died😢
Doesn't tell me what
I thought this was a jumper. Ugh 😩!
🙄 I'm a woman and know you used this wrong
Parent nothing
You really don't know anything about batteries, do you?
Your video is inaccurate, the battery was incorrectly connected. You must press the start button within 30sec when initially plugged in to charge. This is the reason the charger turn off after press “start” (it was plugged in more than 30 sec when you pressed the “start” button).
You press the Start button, then you have 30 seconds to start your car. That function is for jump starting a car, not for the charging function
