Summary of Features

  • An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
  • Charge batteries as low as 1-volt, including flooded, gel, and AGM, as well as automotive, marine, and deep-cycle batteries.
  • It’s not a trickle charger, it’s an advanced battery maintainer. It monitors your battery 24/7, providing intuitive and safe maintenance charging with zero overcharge.
