A Submarine Battery is one of the crucial parts of a submarine and is essential to its efficient operation since underwater machinery requires a lot of electric power. While nuclear submarines can stay underwater for months or even years, diesel submarines must surface after a set amount of time in order to renew their batteries.

A Submarine Battery enables it to operate while requiring less frequent recharging and to remain submerged for extended periods of time. Along with greater energy density, enhanced charge and discharge dynamics, and longer operational lives, it also provides. It helps with running the nuclear submarine and fixing issues with the reactor and generator.

A submarine's power source when submerged and rising to the surface is a submarine battery. While the submarine is traveling to the sea, it is located in the sub's flooded bottom and runs on the onboard Submarine Battery charger. To prevent negative environmental effects, it is developed without the use of cobalt, nickel, and other heavy metals.
