Equipment features.

Product information:

  • For charging or charge conservation of conventional lead acid, lead calcium/silver batteries, or those of the sealant type (AGM, MF), as well as maintenance-free lead GEL batteries
  • Batteries of various types, with different levels of charge, can be charged simultaneously
  • Each individual charging circuit can be used for testing and charging
  • Indication of battery charge status using bar charts in the display
  • Charging of deeply discharged batteries possible
  • Compact design thanks to primary switched mode power electronics
  • Based on Active Inverter Technology, all processes are microprocessor-controlled
  • Simple wall-mounting


  • Charging: The ACCTIVA Multicharger charges batteries fully automatically and gently until they reach their maximum capacity. After charging, the charger automatically switches over to conservation charging in order to avoid self-discharge.
  • Testing: The ACCTIVA Multicharger uses the measured open circuit voltage to determine the level of charge and the startability of the battery.
  • Replacing: If the vehicle’s battery is removed or replaced, stored data (e.g. radio, clock, etc) is retained. The Acctiva Multicharger temporarily replaces the battery as the power supply unit.

Protective features:

  • Electronic reverse polarity protection
  • Thermal overload protection
  • Safety cut-out
  • Electronically safe
  • Short-circuit protection
