I've just bought a car and I need to buy a battery charger for maintenance and in case I leave the lights on overnight (it's happened before).
The existing battery is 750 CCA, and 100AH.
I'm aware that there are different qualities of chargers, and that a charger with more stages is strictly better. I'll be getting a good one.
My question is, is a small charger capable of charging a big battery from near dead flat? For instance, could you charge this battery from near flat (but still above 3V) to full on a 4A or 6A charger?
From reading the literature from battery charger makers, they recommend a 10 - 12 amp charger for a battery like this, and don't recommend a smaller charger, but I suspect that's just part of their upselling. The speed of charge isn't important to me.
