The sealed lead acid battery (SLAB) is also a 24 vdc 9.5 amp hour, sealed battery.
The battery is charged by the battery-charging relay. A battery low sensing relay will
cause the BATT LOW CHARGE caution light to illuminate when the battery charge
reaches 23 volts. The battery will not be disconnected from the dc essential bus. No
internal monitoring of the battery is possible, and the BATT FAULT caution light cannot
illuminate. For a battery at 80% charged, battery life will be approximately 38 minutes
day, and 24 minutes night. If the battery is left ON the battery will completely discharge
