How Do I Charge My Cars Battery With A Charger What Volts, What Settings

My hummer's battery is dead after not driving it for two weeks. I thought it was a bad battery but when i brought it to autozone they charged it for 4-5 hours and it was working perfectly again.

Definitely Alternator

Have been having problems with flickering lights (dash / headlights / interior lights) and lumpy performance through the revs. Checked voltage in Battery (which I recently replaced) and it's 12.5 volts with engine off, and 14.4 v engine on. If I turn everything on (all lights + main beams + a/c + heated front/rear screens + radio + blower), then voltage across battery reads 12.1->12.3 volts, if I rev engine it has negligible effect to the V. However, if I turn say two thirds ...

Why Do Two Car Batteries With Identical Voltage Readings Have Completely Different Carstarting Ability

My car battery was turning my car over too weakly. Its voltage reading was 12.8 volts with the car turned off after sitting a while after being driven. I bought a new battery and before installing it in the car, voltage tested it. It was also 12.8 volts, no doubt because it had been sitting on the store shelves for a period of time. I expected my car to initially start slowly, just like the old battery, ...
