Charger, Maintainer, Cleaner & Tester 4-Pack – 50 Watt (6 & 12 Volt) (LCD) (8500)


With PULSE CLEANER Desulfation “Battery Extending” Technology!

The Battery Saver™ (8500) is a Multi-Pack bundle offering four of our more powerful units that work with Lithium Ion and Lead Acid batteries, with faster charging speeds, as well as being able to maintain more batteries in parallel and testing a battery’s health and condition. Each unit has built-in PULSE CLEANING technology to clean the plates inside the battery and extend that battery’s life.

In addition to all the Charging / Maintaining features these units provide, they also have a built-in LCD readout to display the charging voltage, AMP output and a lateral charging bar which graphically illustrates the percentage the battery is charged. The tester not only indicates the life left in a battery, but also checks the charging system in the vehicle while the engine is running.
