Sterling Pro-Budget Digital 12v-10amp Battery Charger
3 Stage charger power packs - This new compact design, low cost, switch mode, 4 step, constant current, signal output battery charger range is designed for use where only a single battery bank is to be charged. After the battery is charged the unit drops to a safe float voltage and the unit will act as a power pack, safely delivering power to feed any on board power requirements up to the maximum current of the charger. (due to the reverse polarity protection of this unit, a battery must be connected to the charger with a minimal charger in the battery before the charger will activate, or become a power pack.
This charger is extremely compact, and is preset so it can be used for open lead acid, sealed lead acid, gel etc, or any battery where the charger voltage should not exceed 14.4 volts.
