Motorcaravan Boosters

Booster WA 121545

When using an energy-saving charging alternator (Euro 6), using a booster is required because the charging voltage fluctuates very strongly (12,6V to 15V).

When using a conventional alternator, the living area battery charge can be improved by using a booster.

  • Charges 12V lead-acid, lead-gel, AGM and lithium batteries while driving, regardless of alternator voltage
  • For AGM batteries that require a charging voltage of 14,7V, using a booster is required
  • Charging characteristic curve: IUoU (current-dependent switchover to trickle charge)
  • Temperature compensation when a sensor is connected
  • Maximum charging current is adjustable in four increments: 45 A, 55 A, 63 A and 70 A
