2.4.1 Battery Maintenance

2.4.1.1 Conditioning a Battery

A battery needs at least two conditioning cycles when it is used for the first time. A battery

conditioning cycle is one uninterrupted charge of the battery, followed by an uninterrupted

discharge of the battery. Batteries should be conditioned regularly to maintain their useful

life. Condition a battery once when it is used or stored for two months, or when its run time

becomes noticeably shorter.

To condition a battery, follow this procedure:

1. Disconnect the monitor from the patient and stop all monitoring or measuring.

2. Insert the battery in need of conditioning in the battery compartment of the monitor.

3. Apply AC power to the monitor and allow the battery to charge uninterruptedly for 10

hours.

4. Remove AC power and allow the monitor to run on the battery until it shuts off.

5. Apply AC power again to the monitor and allow the battery to charge uninterruptedly

for 10 hours.

This battery is now conditioned and the monitor can be returned to service.

2.4.1.2 Checking a Battery

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 power to the monitor and allow the battery to charge uninterruptedly for 10

hours.

3. Remove AC power and allow the monitor to run on the battery until it shuts off.

4. The operating time of battery reflects its performance directly.

If the oprating time of the battery is noticeable shorter than that stated in the specifications,

replace it or contact your service personnel,
