The sleep function disables the battery’s discharge current, turning off any connected load. It also minimizes any parasitic draining of the battery and enables maximum storage duration. To enable the sleep function, push the SoC button for three (3) seconds. This will turn off the battery discharging, shown via an illuminated power-down animation on the SoC indicator. To wake up the battery, push the SoC button for three (3) seconds. This will re-enable the discharging current, shown via an illuminated power-up animation on the SoC indicator. NOTE: While the Bosch LB24DP Dual Purpose Battery series will still accept charging current in Sleep Mode, this is not the case for the Bosch LB24DC Deep Cycle Battery series.
