Does anyone know what would cause corrosion at the negative battery terminal of a 7 amp/hour sealed lead acid battery?
There is a picture at
This unit is in a protected place - maybe too protected as the box may be getting too hot.
Is this caused by overcharging?
On a related note, I'm looking for some sort of modular battery charger that can charge these batteries. It should be able to take 24V DC input, and output whatever is needed to trickle charge the above battery. Anyone have any sources for this kind of product? I'm going to need at least 10 of them. Ideally they will be quite small (matchbox size or smaller) and rugged.
