Lead-Acid Battery Basics

When the battery provides current, there is a voltage drop across R S, and the terminal voltage v < v s. To charge the battery, a voltage v > v s. must be applied to the battery terminals. A real battery consists of a constant voltage source with voltage v s = 12.7 V and an internal resistance R s = 0.1 Ω.

Lead–acid battery

Overcharging with high charging voltages generates oxygen and hydrogen gas by electrolysis of water, which bubbles out and is lost. The design of some types of lead–acid battery (eg "flooded", but not VRLA (AGM or gel)) allows the electrolyte level to be inspected and topped up with pure water to replace any that has been lost this way.
