Use the power supply to recharge the battery from an AC power source. This
takes a maximum of 14 hours when monitoring simultaneously, or eight hours if
no monitoring occurs. Typical times are 11 hours if you are monitoring
simultaneously, or 4.75 hours if no monitoring occurs.
A stored battery loses capacity over time. To minimize loss of capacity, recharge
the battery at least every six months. A battery typically has three to five years
shelf life.
The only preventive maintenance task required for the monitor is battery
exchange. Life expectancy of a battery depends on the frequency and duration of
use. The battery should be replaced every two years.
