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 them. Additionally, some good working practices are also given regarding the correct
disposal of the batteries. This section only applies if you have the FM20/FM30 battery option #E25.
About the Battery
The rechargeable Lithium-Ion 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).
To get the most out of the batteries, observe the following guidelines:
•
Condition the battery only upon maintenance request prompt on display.
• If a battery shows damage or signs of leakage, replace it immediately. Do not use a faulty
battery in the monitor
.
NOTE
• Battery Disposal —The battery should be disposed of in an environmentally-responsible manner.
Consult the hospital administrator or your local Philips representative for local arrangements.
Do not dispose of the battery in normal waste containers.
• Battery Storage — The battery should be max. 50% charged for storage.
NOTE
The battery will discharge over time if it is stored inside the monitor without AC power connection.
The reported values “remaining capacity” and “runtime” will become less accurate when the battery is
stored inside the monitor without AC power connection for a longer period of time (i.e. several
weeks).
Checking the Battery Status
When the monitor is connected to the AC power supply, the battery charges automatically. The battery
can be charged remotely from the monitor by using the battery charger. Use only the 865432 Smart
battery conditioner.
Battery status (level of charge) is indicated in several ways:
•
LED on the front panel of the monitor
• Battery gauge
• Display of battery time below gauge
• Battery status window
• INOP messages
The AC power LED is only on when the power cord is connected and AC power is available to the
monitor. In this case, the battery can be either charging or is fully charged.
