Purkey’s Steady Charge: Top 10 of 2019

Posted: December 17, 2019

Trailer refrigeration and heating units rely on accessory batteries, but inactive batteries will naturally discharge over time. To compound matters, emerging trailer telematics systems can steadily drain power from starter batteries.

The Purkey’s SteadyCharge will maintain such batteries for months on end, without the risk of overcharging, and will run whenever the tractor is connected to the trailer.

No extra charging cables are needed, either. The system automatically recharges over the seven-way connector without interfering with other devices that rely on the auxiliary circuit.
