FAQs About This Product

Ask a Question

  • The advertising seems to imply this charger can cure sulfated batteries. I this true? If so how long might that take.Can I leave it connected over the winter?

    I'm not sure "cure sulfated batteries" is the best way we would describe this charger. The Charge Master series (CM1A, CM6A and CM16A) are very good and reliable chargers. They are extremely good at bringing batteries with low voltage back to proper charge and do condition the battery by removing some sulfate buildup. However it is not a true frequency based pulse charger if that is what you are looking for.

    Yes it can be left connected over the winter.
