Available for 6V,12V and 24V applications these chargers are powerful but compact enough to be kept in a toolkit so that a flat battery can be quickly charged when away from home. The charger provides an initial boost followed by top-up and maintenance cycles for batteries of up to 100Ah capacity. This compact charger uses clever circuitry to provide a three stage charging cycle that will bring any serviceable battery from a discharged state to full charge in hours, and then keep it ready to go.
