Battery Information
4-16 Basic Operation
 Do not incinerate batteries or expose them to temperatures above 60
o
C
(140
o
F).
If a battery has been dropped or banged against a hard surface, whether
damage is visible externally or not:
 discontinue use.
 dispose of the battery in accordance with the disposal instructions.
Lithium-ion Rechargeable Battery Storage
When storing rechargeable batteries, make sure that the battery terminals
do not come into contact with metallic objects or other conductive
materials.
If batteries are stored for an extended period of time, they should be stored
in a cool, dry place, ideally at 15
o
C (60
o
F), with a state of charge of 20% to
90%. Storing batteries in a cool place slows the aging process.
The batteries should not be stored at a temperature outside the range of
-20
o
C (-4
o
F) to 50
o
C (122
o
F).
Stored batteries should be should be charged to at least 90% of their
capacity every 6 months. They should be charged to full capacity prior to
use.
Note — Storing batteries at temperatures above 38
o
C (100
o
F) for extended
periods of time could significantly reduce the batteries' life expectancy.
Inserting/Removing Batteries
Warning
Arrhythmia relearning is initiated whenever the MX40's batteries are
removed for one minute or longer. Be sure to check your patient’s
arrhythmia annotation for accuracy whenever relearn has occurred.
Caution
Remove the batteries before storing the MX40 for an extended period of
time.
