Lithium-ion Rechargeable Battery Care
Care of the rechargeable battery begins when you receive a new battery for
use and continues throughout the life of the battery. The table below lists
battery care activities and when they should be performed.
Activity
When to Perform
Perform a visual inspection.
Before inserting a battery in the MX40.
Charge the battery.
Upon receipt, after use, or if a low battery
state is indicated. To optimize
performance, a fully (or almost fully)
discharged battery should be charged as
soon as possible.
Clean the battery
At each patient discharge, or in cases
when the battery is exposed to
contaminants.
Charge stored batteries to at least 90% of
their capacity every six months.
When not in use for an extended period
of time.
Decommission the battery
When any of the following INOPs are
displayed on the MX40:
TELE SERVICE BATTERY
TELE BATTERY TEMP
Rechargeable batteries are charged using the IntelliVue CL Charging
Station. For information on charging station use, see Charging Li-ion
Rechargeable Batteries p. 14-8 .
Note — The battery capacity of re-chargeable batteries degrades over time
and number of recharge cycles. Toward the end of its useful life, the battery
capacity may be reduced by 25-30%. If this reduced battery life is
unacceptable based on your use model, Philips recommends replacing the
rechargeable battery sooner.
Lithium-ion Rechargeable Battery Handling Precautions
Lithium-ion batteries store a large amount of energy in a small package.
Use caution when handling the batteries; misuse or abuse could cause
bodily injury and/or equipment damage.
 Do not short circuit - take care that the terminals do not contact metal
(e.g. coins) or other conductive materials during transport and storage.
 Do not crush, drop or puncture - mechanical abuse can lead to internal
damage and internal short circuits that may not be visible externally.
 Do not apply reverse polarity.
