Two compact black rectangular chargers with LED display and IP65 rating

BatteryJack inc. 2-pack 6V 12V 2A smart charger maintainer IP65

SKU CH-QGKB-ERDRJ

Two smart chargers maintain 6 V and 12 V lead-acid and LiFePO4 batteries up to 120 Ah with IP65 protection

  • Battery TypeAGM
  • Dual 2 A units charge two batteries simultaneously
  • Smart 6 V / 12 V detection matches voltage automatically
  • IP65 sealed housing resists dust, oil and moisture
  • LED display shows mode, charge level and errors
  • Microprocessor control revives 4–120 Ah batteries without overcharging

Two-pack smart charger for 6 V and 12 V batteries

This two-pack supplies two identical smart chargers that handle both 6 V and 12 V lead-acid and LiFePO4 batteries. Each unit is rated IP65 for dust and moisture resistance and carries CE certification. Microprocessor control prevents overcharging while maintaining batteries from 4 Ah up to 120 Ah.

Replaces separate 6 V and 12 V maintainers

A single charger covers both voltages, removing the need to keep two different maintainers on the shelf. The jump is worth it when you service motorcycles, cars, ATVs, boats, ride-on mowers or other equipment that mixes 6 V and 12 V systems. Interchangeable alligator clips and ring terminals speed up connection changes.

Suits owners with multiple small vehicles

Ideal for households or workshops that keep several seasonal batteries topped up without daily attention. Not for users who need rapid charging of deeply discharged high-capacity packs, or for anyone requiring a charger that supports chemistries beyond lead-acid and LiFePO4.
