Battery Guard

Avoid excessive discharge of your battery

Battery guards, also called battery protect, help to extend the lifespan of your batteries.

Although they were designed for it, it is possible to discharge so-called deep cycle batteries too much. For all lead-acid batteries the lifetime depends on the depth of discharge (D.O.D.). Although batteries for cyclic use – a cycle is a single charge and discharge – do more cycles than other batteries, the maximum number of cycles is influenced significantly by the D.O.D. The only way to maximize the number of cycles, thus the life of your battery, is to limit the battery voltage. The battery is then discharged until it reaches the battery voltage set. This is called low voltage protection. This so-called under voltage protection can be achieved by using a battery guard.

The Cellpower Battery Guard protects your battery

A Cellpower Battery Guard (or Battery Protect) switches the current of your battery to the power consumer off, when a set battery voltage is reached. There are battery guards for battery sets of 12V or 24V. Larger Cellpower Battery Guards are equipped with an alarm contact which can send a signal to, for example, a warning light.
