Cole Hersee Company introduces its new Smart Battery Isolator 48525 and 48530. Ideal for trucking applications, this product prevents loads on the auxiliary battery from draining the starting battery.

The isolator provides a more flexible system than traditional isolators, as it is not specific to an alternator type. Additionally, Cole Hersee's Smart Battery Isolator is smaller, lighter, and generates less heat. Because the smart battery isolator reduces charging system workload by not connecting to the auxiliary battery until the primary battery is charged to 13.2 volts, there is lower strain on charging components, extending the product life.

No diode efficiency losses occur when using Cole Hersee's isolator, and it also allows bi-directional charging from alternator or from other power chargers/converters. Easy to install, it also features an LED status indicator and operational start assist.

The Smart Battery Isolator is available in 85- and 200-amp versions. For more information, visit
