What is a Lead-Acid Battery? | Haynes Publishing

The voltage should typically be around 12.6 volts when the battery is fully charged, and refers to how much energy is stored in the battery. Think of voltage as the battery''s potential to flow electricity. Whereas the current, measured in amps, is the rate at which the electricity flows. Batteries used in cars are lead-acid batteries. They

Battery Specific Gravity Temperature Correction
