During a charger test on sealed lead-acid batteries, what is the voltage per cell that should be observed?

• A. 1.75
• B. 1.95
• C. 2.10
• D. 2.30

Answer: (D)

During charging, each cell of a sealed lead-acid battery is driven toward a higher voltage, and the charger for a typical 12V battery is set to about 13.8V in total. Since a 12V pack has six cells, dividing 13.8V by six gives roughly 2.3V per cell. So the observed voltage per cell should be around 2.30 volts. Values much lower (like 1.75V or 1.95V) would indicate undercharging, while 2.10V is also below the typical charging target. 2.30V per cell corresponds to the proper charging voltage for these batteries.
