Checking a Battery
The battery performance test must be performed every two years, before monitor repairs, or
whenever the battery is suspected as being the source of the problems. The performance of a
rechargeable battery may deteriorate over time. To check the performance of a battery,
follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring or measuring.
2. Apply AC/DC power to the monitor and allow the battery to charge uninterrupted for
10 hours.
3. Remove AC/DC power and allow the monitor to run from the battery until it shuts off.
4. The operating time of battery reflects its performance directly.
Please replace the battery or contact with the maintenance personnel if its operating time is
significantly lower than the specified time.
NOTE
z The battery might be damaged or malfunctioned if its operating time is too short
after being fully charged. The operating time depends on the configuration and
operation. For example, measuring NIBP more frequently will also shorten the
operating time.
z When a battery has visual signs of damage, or no longer holds a charge, it should
be replaced. Remove the old battery from the monitor and recycle it properly.
23.4 Battery Recycling

batteries, follow local laws for proper disposal.
WARNING
z Do not disassemble batteries, or dispose of them in fire, or cause them to short
circuit. They may ignite, explode, leak or heat up, causing personal injury.
