695 ratings

Key item features

  • Compact Powerhouse: This 1A 6V/12V smart charger is 35% smaller than its predecessor, the G750, yet delivers 35% more power, serving as an all-in-one battery charger, maintainer, trickle charger, and desulfator.
  • Versatile Compatibility: Designed for 6-volt and 12-volt sealed lead-acid batteries, including flooded, gel, AGM, SLA, VRLA, and maintenance-free types, as well as lithium-ion (LiFePO4) batteries, for various vehicles and equipment.
  • Intelligent Charging: Features an integrated digital thermal sensor that adjusts charging based on ambient temperature, preventing over-charging in hot conditions and under-charging in cold climates.
  • Dead Battery Revival: An intelligent start-voltage sensor can detect and charge batteries as low as 1-volt, with a Force Mode available to manually initiate charging for completely dead batteries (down to zero volts).
  • Battery Restoration: Utilizes an advanced repair mode with slow pulse reconditioner technology to automatically detect and address battery sulfation and acid stratification, restoring performance and extending battery life.
  • All-Weather Durability: Engineered for dual-purpose use, both indoors and outdoors, providing weatherproof and waterproof protection against external elements throughout the year.
