Reviving "AGM" batteries???

Does anyone have a procedure for reviving "AGM" batteries? The one in my camping trailer won't hold a charge, and it's from only 2017. I've tried regular lead-acid procedures, but not a lot of improvement. Are there special procedures for AGM-type batteries?

There are battery chargers with a "AGM" setting. A buddy of mine used to work at a recycling center and would hook the charger to a regular battery and hook that battery to the AGM battery. He said he revived many AGM batteries that way.

yup, you need to trick the automatic charger into seeing its normal battery characteristic that the AGM sometimes wont supply. Hook them up in parallel, or put the charger on full manual and monitor it. Sometimes that works for a stone dead battery too, just keep it charging in parallel for about a week.

Thanks guys for the replys. I can get the charger to charge it...it just won't hold a charge for more than a day or 2.

Interesting facts on batteries in general:
>Only 30% of batteries sold today reach the 48-month mark.
>80% of all battery failure is related to sulfation build-up,
>A new fully charged battery left sitting 24 hours a day at 110°F for 30 days would most likely not start an engine.
>Low electrolyte level. Battery plates exposed to air will immediately sulfate.
>Don't add new electrolyte (acid), only add distilled water to a low battery
>Don't use unregulated, high-output battery chargers to charge batteries, they can be used but you need to monitor and amp down the amperage after ~80% charge.
>electronic pulse chargera/conditioners claim to knock sulfation off the plates by blasting them with an opposite charge cycle.

Hello,
Just some interesting information on batteries in general.
Has lots of links to information on all types of batteries.
