Awesome Video ❤. I bought the same exact battery and centech charger. If my AGM is reading 12.2. Do I change the centech settings to Quick Charge or Trickle like the video did for 13.0 reading?? My apologies still i am learning all this
No reason to apologize we are all learning. I use the middle setting when that is complete I use trickle charge until the battery is full. Thanks for your comment.
1. Keep battery charged, especially before storage. Use Meter to test. Use charger. 2. Keep battery clean, including 3. Keep battery ventilated, especially when charging 4. Check battery regularly (monthly?) during Storage, best in cool area
Hiya Shoestring! I just put one of those Harbor Freight solar 12-volt batteries in my riding lawnmower. My external charger does have an AGM button on it but the mower charging system doesn't. Will that be okay when using the mower and the charging comes from the mower charging system? Great video!
I have a 100 watt solar panel, a 10 amp PMW charge controller and a 100 ah AGM battery. Is there anything to consider when keeping the system continually or always connected? Thank you very much for you informative videos.
AGM battery was given too me too look at? Friend removed plugs an flipped over too drain? What fluids are too be added an too what level? Or is anything added? First thing is youvmeasured current? Not levels?
From your description, it sounds like you have a Flooded Lead-Acid Battery (not an AGM). A flooded lead-acid battery has plugs which cover cells filled with water. Please use Distilled Water for the battery, not tap water. Look inside each cell and there will be a line which shows how much water to add. I have a video which explains how to use and take care of this type of battery (here: ruclips.net/video/LG8j32ATazM/видео.html). AGM batteries are sealed so you cannot drain or add water. If you are certain it is an AGM battery, then it has been damaged and please do not use it. Hope this helps. Thanks for your comment.
Hi Shoestring! Thanks for the video! A comment on a different video mentioned something to the effect: "If you don't use AGM batteries fairly frequently, then they go bad." Is their any truth to that? I've got the same battery and charged it with the little Centech float charger for 6hrs. My battery was 12.64vdc and after 6 hrs. It, initially, showed a 12.8vdc charge. Checked the battery a day later and it shows 12.6vdc. Yet again, I read on the internet that AGM batteries should not be charged for more than 3 hrs. Any advice you have would be appreciated! Thanks!
Hi, I hv seen many video to revive this type of AGM battery to add battery water, should we add some amount of batt water thru the years? Or how do we know tht the glass mat is completely dry? Thanks
Hi there i am getting all sorts of information about discharging i was told by 3 people that 11.8 volts switch off as thats 70% discharge i want to drain as low as possible 100ah i no it will shorter life was told 400 cycles at most
The lower you discharge an AGM battery (below 12.1) the more you will damage it. A lithium battery does not care how far you drain them. Thank you for your comment.
I’m assuming that you’re referring to the depth of discharge within the usable voltage range of lithium batteries, here. More specifically the usable voltage range of approx. 2.9v-4.2v/cell that constitutes “0%” to “100%” capacity of each cell. Every battery chemistry absolutely does have a voltage cutoff point for over-discharging and over-charging. Charging or draining lithium cells to levels outside of the stable operating thresholds of the cell’s chemistry causes permanent, irreversible damage to the cell’s capacity, and ability to sustain its rated current-draw. I understand that you’re likely referring to the DOD in applications with internal lithium battery cells (or other-voltage series packs) that have BMS monitoring and automatic high/low V cutoff, such as a cell phone battery, and notify the user of the current usable percentage remaining to “0%” (2.9v).
Very clear and informative. No introductory waffle. Thank you. Didn't realise that one could store these type of batteries on their side.
Thanks for the kind words and comment.
What if my riding mower has an AGM? Mowers dont have alternators, so what keeps the battery charged? How often do I charge it up ?
My riding mower also has an AGM. It came with a battery charger included. I charge it back up after each use. Thanks for your comment.
Video was to helpful everybody knows how to maintain a battery I thought you was going to tell her something we didn't know about AGM
Thanks for your comment.

It would depend on how high the mower will charge the battery. Don't overcharge it. Thanks for the comment.

That combination should work well connected together all the time. Thanks for your comment
Would you recommend keeping AGMs hooked up to the trickle charger all the time while in storage in my shed during the cold, Michigan winter months?
Yes I would, try to keep lead acid batteries charged all you can
Thanks for your comment.

So it is essential to test and charge even a new battery before installing in your vehicle .
I also test and charge a battery before I use it. Thanks for your comment.

I keep all my AGM batteries charged all the time. They will lose a charge if they are left uncharge for a period of time. Thanks for the comment
I have destroyed many batteries not doing these things
Always take care of your batteries. Thanks for your comment.

Do not try to add water to an AGM battery. They will not need water. Thanks for your comment
@@shoestringprep if they don't need water. Wat then do we need to do wen they no longer hold power..?
@@obaroaluya3762 when the AGM battery no longer holds any power you simply replace it. Thanks for your comment.
@@shoestringprep wat about deep cycle batteries AGM..?
@@obaroaluya3762 AGM batteries of any types do not need water. Thanks for your comment.

How can I keep my flooded battery alive
Keep the battery charged and don't let the voltage drop to low. Thanks for your comment.
