Supply Battery

A battery that enables a self-sufficient power supply, i.e. it stores energy for later, grid-independent, permanent use.

Typical application is the supply of electrical consumers on boats, in mobile homes or buses, where they are installed as an additional battery in order not to overburden the starter battery. In standby applications they take over the power supply if the main power source fails. And they serve as a buffer storage for solar and wind power plants.

A battery for these applications must be particularly cycle resistant.

Apart from this, there are supply batteries in almost all battery classes. As these are mostly stationary applications, wet batteries are also used, especially in the hobby sector and for smaller solar applications.
