8.4 Conditioning the Lithium Ion Battery
A lithium ion 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 a complete, uninterrupted discharge of the battery. A lithium ion
battery should be conditioned regularly to maintain its 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 lithium ion battery, follow this procedure:
1. Disconnect the pulse oximeter from the animal and stop all monitoring and
measuring procedures.
2. Place the lithium ion battery in need of conditioning into the battery compartment
of the pulse oximeter
3. Place the pulse oximeter in the Charger stand and connect the AC mains. Allow the
battery to be charged uninterruptedly for above 2 hours.
4. Remove the AC mains and allow the pulse oximeter to run from the battery until it
shuts off.
5. Replace the pulse oximeter in the Charger stand and connect the AC mains. Allow
the battery to be charged uninterruptedly for above 2 hours.
Now, the battery is conditioned and the pulse oximeter can be returned to service.
