23.2 Conditioning the Batteries
A battery needs at least two conditioning cycles when it is put into use for the first time. A
battery conditioning cycle is one complete, uninterrupted charge of the battery, followed by
an uninterrupted discharge of the battery. Batteries should be conditioned regularly to
maintain their useful life. Condition the batteries once when they are used or stored for two
months, or when their run time becomes noticeably shorter.
To condition the batteries, follow this procedure:
1. Disconnect the patient monitor from the patient and stop all monitoring and measuring
procedures.
2. Insert the two batteries in need of conditioning into the battery slots of the patient
monitor.
3. Apply AC power to the patient monitor and allow the batteries to charge uninterruptedly
for above 6 hours.
4. Remove AC power and allow the patient monitor to run from the batteries until it shuts
off.
5. Apply AC power again to the patient monitor and allow the batteries to charge
uninterruptedly for above 6 hours.
6. This battery is now conditioned and the patient monitor can be returned to service.
