A few years ago, we discovered that AGM batteries fail if they are not fully charged frequently. Has this been resolved?

[john61ct]

That is true for all lead chemistries, where "damaged" means losing lifespan.

AGMs are more susceptible than FLA, Gel less so.

Firefly Oasis are unique in withstanding PSOC abuse, have a periodic routine to restore capacity.

LFP has no issue at all, in fact prefers to sit depleted.

I am not selling anything. I use Duracell EGC2 battery bank and I am well satisfied after two years. Duracell is a house brand of East Penn. The same as Deka. East Penn makes other labels on contract, and they could change. Such as West Marine, Diehard, and Napa.

Nope, not everything. Many things but not everything.

Bought a used truck once with 5 year guaranteed battery by an auto parts store like O'Reilly. Went through 2 that routinely died at 3 years and went with a good brand, Interstate. Still going 6 years later....

Could people please stop talking about **starter** batteries as if that is the same topic?

Apples and oranges, chalk and cheese.
