2.5.2 Battery Maintenance

Conditioning a Battery

A battery should be conditioned before it is used for the first time. A battery conditioning cycle is

one uninterrupted charge of the battery, followed by an uninterrupted battery discharge and

charge. . Batteries should be conditioned regularly to maintain their useful life.

NOTE

z Condition a battery once when it is used or stored for 3 months, or when its

operating time becomes noticeably shorter.

z The actual battery capacity will decrease over time with use of batteries. When a

monitor operates on batteries that have been used before, the full capacity battery

symbol does not indicate the capacity and operating time of this battery can still

fulfill battery specifications in the operator’s manual. When conditioning a

battery, please replace the battery if its operating time is significantly lower than

the specified time.

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 slot of the monitor, and leave the

other slot empty if your monitor has two slots.

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

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

5. Apply AC power again to the monitor and allow the battery to charge uninterrupted for 10

hours.

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

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 power to the monitor and allow the battery to charge uninterrupted for 10 hours.

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

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

If your monitor has two battery slots, you can check two batteries at the same time. Please

replace the battery or contact with the maintenance personnel if its operating time is significantly

lower than the specified time.
