What is the per-cell voltage for a six-cell battery as listed?

• A. 2.11 volts per cell
• B. 2.0 volts per cell
• C. 1.9 volts per cell
• D. 2.2 volts per cell

Answer: (A)

In a series battery, the total pack voltage is the sum of each cell’s voltage, so the per-cell voltage is what you get when you divide the pack voltage by the number of cells. For a six-cell lead-acid pack, a fully charged cell is typically about 2.11 volts, which means the full pack voltage is around 12.66 volts. That makes 2.11 volts per cell the best match to a fully charged six-cell pack. The other values would imply slightly different states of charge (roughly 12.0 V, 11.4 V, or 13.2 V for the pack), which aren’t the typical fully charged reading.
