AGM batteries - do they demand a minimum charge current?

[Roil]

But that is all theory. When the bible is silent on the subject, I think we need input from those with the latest edition or current experience.

, or maybe we just need a reader with better understand of what's written than me.

thanks for the answer.

I have search the different treads and found many statements of minimum current for FLA batteries, but none conserning a minimum current for AGM batteries.

Does this mean that there are no such minimum current?

I must admit i have read chapter 24 in the battery bible without finding the answer, that being said, it doesn't mean that the answer isn't there

Clarification is much appreciated

Since you should not need to worry about electrolyte stratification in an AGM, that would not set a minimum bulk stage current requirement.
But you should still have enough to recharge them as promptly as possible after use. I suspect that taking all week to recharge after a weekend would not be good in terms of sulphation, but it would only count as one cycle instead of 7 in terms of Depth of Discharge, so that part may work out!

I think that like FLAs, a constant trickle charge (above the Float voltage) with no discharge would tend to encourage growth of lead fingers from the plates, which could be a totally separate problem. Possibly the presence of the glass mat would keep that from being a concern.
