Battery
Guidelines
To get the most out of the battery, observe the following guidelines:
• The shelf-life of a fully charged battery is about 6 months.
• After a battery has been activated, keep it charged. If it is not in use, recharge it every 3
to 4 months.
• Condition the battery approximately every 200 deep discharges.
• Remove the battery from the monitor if it is not being used regularly. (Leaving the
battery in a monitor that is not in regular use using the battery will shorten the life of
the battery).
• Battery Disposal - We recommend replacing the monitor’s sealed, lead-acid battery at 2
year intervals. Follow local governing ordinances and recycling plans regarding
disposal or recycling of batteries and other device components.
• Do not dispose of the battery in normal waste containers.
WarningWarning
If the battery shows signs of damage or signs of leakage, replace it immediately. Do not
use a faulty battery in the monitor.
Checking
the Battery
Status
When the monitor is connected to the AC (mains) power supply, the battery charges
automatically.
Battery status is indicated several ways:
• LEDs on the front panel of the monitor.
• Battery gauge on the monitor’s main monitoring screen.
• INOP messages
The AC LED is only on when the power cord is connected and the AC power is available to
the monitor. In this case, the battery can be either charging or fully charged.
