battery generated output AC power in the event of an input power failure. For the
batteries to charge, input AC power must be present, the UPS/BATTERY switch must be
in the position, and the MAIN INPUT breaker must be ON.

Charging the batteries can take up to 14.5 hours for a 90% recharge. The recharge time
may be considerably less if the batteries are not fully discharged.
