How many cells does a 24-volt lead-acid battery have?

A 24-volt lead-acid battery typically consists of 12 cells connected in series. Each lead-acid cell has a nominal voltage of approximately 2 volts. When you multiply the number of cells (12) by the voltage of each cell (2 volts), the total voltage adds up to 24 volts. This standard configuration is common in many applications, particularly in aviation, where reliable and consistent battery performance is crucial.

Understanding the structure of lead-acid batteries is important for aviation mechanics, as it relates to battery maintenance, replacement, and troubleshooting. Other configurations or types of batteries may exist, but for a standard 24-volt lead-acid battery, the number of cells is specifically 12.
