Oxon Power has introduced a new heavy-duty truck starting system designed to separate engine starting from hotel loads, a move the company says can improve starting reliability, reduce downtime, and extend battery life.

The HyperStart system replaces one conventional Group 31 battery in three- or four-battery truck configurations. Rather than relying on all batteries to handle both engine cranking and auxiliary electrical loads, HyperStart is dedicated to starting the engine while the remaining lead-acid or AGM batteries continue powering hotel loads.

“In most heavy-duty trucks, Group 31 batteries are typically connected in parallel for starting and hotel loads,” said Paul Menig, board advisor at Oxon Power. “Technology has advanced to where a single HyperStart assembly can ensure starting power while the remaining batteries continue to support hotel loads and can be discharged more deeply since they don’t have to start the engine.”

Menig said the approach can help owner-operators avoid costly no-start situations that can result in missed deliveries, roadside service calls, and lost revenue. Fleets, meanwhile, may benefit from fewer roadside events, lower maintenance costs, reduced battery replacements, and improved equipment uptime.

The company says separating starting duties from hotel loads can extend the service life of conventional batteries to as much as five to seven years, depending on factors such as battery quality, charging practices, and depth of discharge.

HyperStart is designed as a drop-in replacement, connecting to existing battery cables without rewiring. Oxon says installation can be completed in about 10 minutes and the system operates automatically without driver intervention.

The 18.5-lb. unit also incorporates an internal heater and battery-management controls to maintain starting capability in temperatures as low as -40 C.
