I have never for the life of me understood why vehicle/equipment electrical lsystems with 35 amp and up alternators don't boil batteries. Put a five amp charger on a battery and it will be boiling eventually. You can't tell me that charging systems are that sophisticated, especially older ones.
You would think that if you drained your battery and got it started with a 100 amp plus alternator, it would destroy the battery, but it doesn't.
Its simple.... IF charge "voltage" is to high it cooks battery, IF charge voltage is correct for battery, it last forever (well almost) ... Amperage has very little to do with it....
