I've been having a nagging question for a while... I tried googling this and didn't get the answer. Let's say you have a dead battery and put it on a charger at say 10amps. The charger's amp draw needle swings over to 10. and the charging begins. As the battery is charging up,the amp draw lessens. With this, the charger is now pushing out less amps. So my question, does the battery draw the amps it needs dynamically, or does the charger somehow figure out what the battery needs and adjusts itself dymanically? (doesn't matter if it's a manual or automatic charger). I once had a completely dead battery, like 1 volt in it. I decided to waste time and put it on a 6amp charger. After 3 hours of the circuit breaker popping on and off, it finally stopped and battery was able to take a charge. THAT told me the battery was trying to draw more that the 6amps allotted (the charger was a 2/6amp) so the circuit breaker saw the attempt to overdraw 6amps and opened, the it closed a moment later, popped a few minutes after, and kept that cycle going. My guess till the battery had enough charge, it would be happy with the 6amps allowed. So me and a co-worker and going bonkers trying to figure this out. No real reason as to why we need to know this, just one of those.. "Hmmmm......." moments.
