This battery maintainer enables the auxiliary battery bank to remain topped up by using charge from the primary battery, only when the primary battery is connected to a battery charger, wind generator, solar cell, etc. The maintainer is activated when the primary battery reaches about 13.3V and allows excess power to be transferred to the auxiliary battery. The auxiliary battery will then be charged at low current, 1 or 3A, depending on model. It then maintains the charge on the auxiliary battery. If the primary battery's voltage drops below 12.9V the device switches to standby.
