Which header would you consult to learn about the characteristics of a Maintenance Free Battery?

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

Answer: (C)

The per-cell voltage used in the specifications defines the characteristics of a lead-acid battery, especially for a maintenance-free type. A maintenance-free, sealed VRLA battery is typically described at its fully charged state with a per-cell voltage of about 2.11 V. Since a 12 V battery consists of six cells, this corresponds to roughly 12.66 V when fully charged, which matches the common full-charge range you’d expect to see in practice. That’s why the header listing 2.11 V per cell is the place to learn about its characteristics. The other values fall outside the typical fully charged range: 2.0 V per cell would be closer to a discharged state, 2.2 V per cell is higher than the usual full-charge specification and can be outside standard maintenance-free ratings, and 1.9 V per cell is clearly well into discharge territory.
