Blue Power IP65 Charger with DC connector

Li-ion battery mode

A lead-acid battery that that has been insufficiently charged or has been left discharged during days or weeks will deteriorate due to sulfation. If caught in time, sulfation can sometimes be partially reversed by charging the battery with low current up to a higher voltage.

Spec sheet


With up to 95% efficiency, these chargers generate up to four times less heat when compared to the industry standard. And once the
battery is fully charged, power consumption reduces to 0,5 Watt, some five to ten times better than the industry standard.


  • Water, dust and chemical resistant
  • Seven step smart charge algorithm
  • Recovery of fully discharged ‘dead’ batteries
  • Automatic power supply function
  • Automatic compensation for high or low temperature
  • Several other battery life-enhancing features
  • Low power mode to charge smaller batteries
  • Li-ion battery mode
