Two-pack automatic charger

This package contains two automatic battery chargers that handle both 6 V and 12 V lead-acid and LiFePO4 batteries. Each unit delivers up to 4 A and includes selectable modes for charging, maintenance, reconditioning, supply and winter storage. The microprocessor-controlled programme prevents overcharging and suits cars, motorcycles, ATVs, boats and lawn equipment.

Replaces manual trickle units

The smart chargers replace basic trickle or manual chargers that lack voltage selection or desulfation. The jump is worth it when you maintain several seasonal vehicles or need a maintainer that can revive sulphated batteries without supervision. Alligator clips and ring terminals are supplied for quick or permanent connection.

Check battery chemistry and voltage

Verify that every battery you plan to charge is 6 V or 12 V and is a wet, AGM, gel, VRLA, SLA or LiFePO4 lead-acid type. Confirm the charger’s IP65-rated case is suitable for the mounting location and that the 4 A output matches the battery’s recommended charge current.
