battery capacity over 5 years while installed in a LIFEPAK 500 AED at 20°C (68°F)
A new lithium battery pak has a shelf life of 5 years if stored at the proper temperature. Although a
lithium battery may be stored for up to 5 years, it self-discharges over time. Therefore, when the battery
is eventually placed in the AED, its useful life will be reduced depending on how long it “sat on the
shelf.”
To properly maintain nonrechargeable lithium battery paks:
• Do not attempt to recharge (lithium battery paks cannot be connected to the battery charger used to
recharge the rechargeable SLA battery paks).
• Do not use beyond the expiration date marked on the battery label.
• Do not expose to temperatures greater than 50°C (122°F).
• Do not allow electrical connection between the battery contacts.
WARNING!
Possible explosion, fire, or noxious gas.
Attempting to recharge a LIFEPAK 500 nonrechargeable lithium battery pak can cause an explosion or
fire or release noxious gas. Dispose of expired or depleted lithium battery paks as described in these
Operating Instructions.
CAUTION!
Possible battery damage.
Electrical connection between battery contacts can blow an internal fuse and permanently disable the
battery.
