Maintenance
Figure 5-3 SLA battery capacity while installed in a LIFEPAK 500 AED for 3 months without recharging at 20°C (68°F)
To properly maintain SLA battery paks:
• Recharge after each use or once a month, whichever comes first. Maintain a battery recharge record.
• Use only the Physio-Control battery charger designed for use with the LIFEPAK 500 AED. Do not use
any other charger.
• Recharge until the battery charger charge LED is green. This indicates that the battery charger has
completed the fast-charge cycle. Undercharging can cause battery damage.
• Recharge only at temperatures between 15° and 35°C (59° and 95°F).
• Never expose battery paks to temperatures greater than 50°C (122°F).
• Battery paks are best when used and stored between 0° and 35°C (32° and 95°F). Higher
temperatures accelerate the loss of charge and wear out the battery pak sooner. Lower temperatures
reduce battery capacity.
• Do not allow electrical connection between the battery contacts.
WARNINGS!
Possible loss of power during patient care.
Stored batteries lose charge. Failure to charge a rechargeable battery before use may cause device
power failure without warning. Always charge a stored battery before placing it in active use.
Possible loss of power during patient care.
Using an improperly maintained battery to power the defibrillator may cause power failure without
warning. Use the LIFEPAK 500 battery charger to charge the rechargeable battery pak.
