Purkeys SteadyCharge Accessory Battery Charger is designed to monitor and maintain an optimal charge level in accessory batteries, preventing battery depletion during periods of inactivity.

Purkeys’ SteadyCharge maintains accessory batteries during months of non-use without overcharging them, and is operational whenever a truck is connected to a trailer. It eliminates the need for extra charging cables and automatically charges using the trailer’s existing 7-way cable, and it won’t interfere with other devices on the auxiliary circuit, such as the trailer’s ABS system.

The durable, 10-pound SteadyCharge is engineered to meet SAE J1455 testing criteria and is IP66 rated for exterior mounting on the trailer body. The charging system’s logic controller includes a low voltage disconnect (LVD), which protects truck batteries and is programmable to any LVD setpoint. The SteadyCharge also features temperature-compensated charging that automatically optimizes its charging characteristics to match its operating climate.

The SteadyCharge is built to handle harsh road conditions and comes with a three-year warranty. LED status indicators assure users of proper functioning and alert them of any issues.
