What is the standard voltage rating for a lead acid battery?

The standard voltage rating for a lead-acid battery is 2.2 volts per cell. Lead-acid batteries are typically made up of multiple cells connected in series to increase the overall voltage. Each cell contributes approximately 2.2 volts, which leads to common configurations such as a 6-volt battery pack (comprising three cells) or a 12-volt battery pack (comprising six cells). This voltage rating is crucial for determining how the battery can be used in various applications, as it provides the baseline for understanding the electrical characteristics and performance of the battery.

The other voltage values presented do not correspond to the standard rating for a lead-acid cell and are generally associated with different types of batteries or configurations. Understanding this standard is essential for ensuring compatibility with devices and systems designed to operate within certain voltage ranges.
