Battery Handling, Maintenance and Good Practices

This section provides some information on how to handle and maintain the battery in order to
get the best usage from it. Additionally, some good working practices are also given
regarding the correct disposal of the battery.

About the Battery

The rechargeable battery used in the Monitor is regarded as a Smart battery because it has
built-in circuitry. (This circuitry communicates battery-status information to the Monitor.)
If an unused battery does not communicate (the LEDs do not light), a MALFUNCTION
message will appear when it is inserted in a monitor. In this situation it means that the smart
battery is really empty and cannot communicate. Normally the battery is in good order and
the message will disappear after 5 to 10 minutes of charging.
To get the most out of a battery, observe the following guidelines:
• IMPORTANT! Leaving the battery in a monitor running on AC mains power will
shorten the life of the battery. ALWAYS remove the battery from the monitor when it
is not being used regularly as the main source of power for the monitor. Recharge the
battery every 3 to 4 months.
• The shelf-life of a fully charged battery is about 6 months.
• Once a battery has been activated, keep it charged. If it is not in use, recharge it every 3 to 4
• Condition the battery approximately every 50 recharge cycles.
• If the battery shows damage or signs of leakage, replace it immediately. Do not use a
faulty battery in the Monitor.
• Charging rate of the battery:
Monitor Off: 1.4 Amps.
Monitor On: 200 mAmps.
• Battery maintenance - We recommend you use the external Battery Charger and Condi-
tioner (M8043A) to maintain and condition your batteries.
• Battery disposal - Batteries should be disposed of in an environmentally-responsible man-
ner (see also page 115). Consult the hospital administrator or your local Philips representa-
tive for local arrangements.
Do not dispose of the battery in normal waste containers.

Checking the Battery Status

When the Monitor is connected to the AC mains power supply, the battery charges
automatically. The battery can be charged externally from the Monitor by using the Battery
Charger and Conditioner (M8043A).
Battery status (level of charge) is indicated several ways:
• LEDs on the front panel of the Monitor.
• Battery gauge.
• Battery status menu.
• INOP messages.
