A 7.4V lithium battery has a nominal voltage of 7.4 volts. It’s commonly used in devices requiring more power than a single cell can provide. These batteries are typically made up of two 3.7V cells connected in series.

The voltage of a 7.4 V lithium battery will change under different conditions.

The voltage range of a 7.4 V lithium battery is generally as follows:

• Nominal voltage: 7.4V. This is the voltage output by the battery under ideal conditions, usually marked on the battery.
• Full voltage: about 8.4V. When the battery is fully charged, the voltage will reach its highest value, generally around 8.4V.
• Low voltage: about 6V. When the battery is exhausted, the voltage will drop to its lowest value, generally around 6V.
