what is a 1.5 volt battery

A 1.5 volt battery is an electrical power source that produces a voltage of 1.5 volts. It is a classic nominal voltage, and most AA, AAA, C, and D cells are 1.5 volts. The first zinc-carbon dry cells naturally produced 1.5 volts of energy, and this has remained the standard ever since. 1.5 volt batteries come in various sizes and types, including AA, AAA, AAAA, C, and D batteries. They are available in lithium-ion, alkaline, zinc-carbon, and silver oxide batteries. Alkaline and carbon zinc AA and AAA batteries are 1.5V batteries, but AA and AAA batteries may have a nominal voltage in the 1.2 to 3.7V range. A 1.5V battery is typically considered "dead" or depleted when its voltage drops below a certain threshold. For most non-rechargeable 1.5V batteries, a voltage of around 1.0 to 1.2 volts is often considered the cutoff point.
