Challenge: Battery Charging in a third world country

[e1000]

Wow, that’s quite the wish-list…

I was always happy with “topping off” Pb-acid batteries with a cheapo float-charger. Its inherent internal resistance would be enough to control (more or less) the float-voltage to what the battery itself wants to draw.

Agree, I think he’s over-thinking it. Could probably get away with a cheapo car battery charger, but if he’s that worried, the nice ones (NOCO, CTEK) aren’t terribly more expensive.
