Comprises  a range of maintenance chargers that enter a sleep mode between charge pulses, during the sleep mode mains power is turned off. The length and and frequency of pulses is depended on battery recharge level. This cycle helps to minimises sulphation, provides a deep charge while minimising gassing, minimise power usage, and suits multiple battery bank installations.

The 24 volt chargers offer split bank charging, this allows each half of the battery bank to be independently charged. Allowing each battery to take a charge to suit its requirement, prolonging battery life as each has a optimum charge cycle. While allowing the battery bank still to supply intermittent loads even when on a charge cycle.
