Probably a lot more than you'd be able to comprehend.
I just can't figure what you're talking about here with "how many amps its taking the battery to fire".
Mininum amp before battery is dead?
A battery doesn't need amp to fire, it either has contained power or doesn't, this isn't an engine that you need to turn over... electricity/energy is stored, touching a positive to a negative and boom, it's like magic, it works. It's like opening a water system that's under pressure (such as gravity), pop that valve open, and it'll flow, you don't need to use a secondary system to pump it. Like popping a balloon, a controlled hole and the air pushes itself out, a bad ....., and it pops.
What you know that you're talking about might be clear in your head (and only your head), but care to explain your question instead of being arrogant?
