Power Supplies - 20Ah Battery Pack
Battery Pack

The RLH 24V 20Ah battery pack consists of two 12 volt maintenance free sealed lead acid AGM batteries and is contained within a powder coated steel housing with a hinged door and thumb screws. These battery packs are commonly used with AC/DC power supplies and a charge controller to provide uninterrupted backup power in the event of a power outage.

The battery pack is designed to be easily mounted, using a quick-mount plate, that is first attached to the wall, then the battery pack is hung and then secured to the mounting plate. It is designed to be used indoors or in a weatherproof enclosure.

The life expectancy of the internal batteries is up to 5 years. Excessive hot or cold temperatures will decrease battery power and life. Depleted batteries may be replaced in the field by qualified personnel.
