21 Using Batteries
Storing a Battery
A battery should not remain inside the monitor or Battery Extension if it is not used for a longer
period of time. If batteries are stored for an extended period of time, they should be stored in a cool
place, ideally at 15°C (60°F), with a state of charge of 20% to 40%. Storing batteries in a cool place
slows the aging process. The batteries should not be stored at a temperature outside the range of -20°C
(-4°F) to 60°C (140°F).
Stored batteries should be partially charged to 20% to 40% of their capacity every 6 months. They
should be charged to full capacity prior to use.
Storing batteries at temperatures above 38°C (100°F) for extended periods of time could significantly
reduce the batteries' life expectancy.
The battery will discharge over time if it is stored inside the monitor or Battery Extension when not
connected to AC power via the external power supply (M8023A). The reported values for "remaining
capacity" and "runtime" will become less accurate when the battery is stored in this way for a longer
period of time (that is, several weeks).
Disposing of Used Batteries
Dispose of used batteries promptly and in an environmentally-responsible manner. Discharge the
batteries and insulate the terminals with tape before disposal. Do not dispose of the battery in normal
waste containers. Consult your hospital administrator to find out about local arrangements.
Battery Safety Information
Use only Philips batteries specified in the chapter on "Accessories". Use of a different battery may
present a risk of fire or explosion.
Do not open batteries, heat above 60°C (140°F), incinerate batteries, or cause them to short
circuit. They may ignite, explode, leak or heat up, causing personal injury.
If battery leakage should occur, use caution in removing the battery. Avoid contact with skin. Refer
to qualified service personnel.
Do not expose batteries to liquids.
Do not apply reverse polarity.
Do not crush, drop or puncture batteries - mechanical abuse can lead to internal damage and
internal short circuits which may not be visible externally.
If a battery has been dropped or banged against a hard surface, whether damage is visible
externally or not:
dispose of the battery in accordance with the disposal instructions above.
Keep batteries out of the reach of children
Keep batteries in their original package until you are ready to use them.
