Rechargeable
Battery Pak
The rechargeable SLA battery pak requires more maintenance than a lithium
battery pak because it must be recharged periodically. The SLA battery pak
should be recharged monthly or after each use, whichever comes first. SLA
battery paks are most appropriate when the LIFEPAK 500 AED is used on a
frequent basis and for operators who use the AED with a simulator for training.
With an SLA battery pak installed, the LIFEPAK 500 AED automatically turns on
and tests the battery once a week as part of the test. To check the battery level,
turn on the AED and check for battery fault indications. Do not check the status
of more than 3 batteries within a 5-minute period. The AED may not
accommodate more frequent battery checks.
Note: (LIFEPAK 500 Biphasic AED with Readiness Display only) The OK
indication on the Readiness Display is equivalent to BATTERY OK on the AED.
SLA battery paks should be replaced every 2 years or after 200 charge cycles,
whichever comes first. At room temperature (+20°C or +68°F), a new, fully
charged SLA battery pak can deliver approximately 59 discharges at 360 joules,
with a minimum of approximately 43 discharges at 360 joules.
To properly maintain SLA battery paks:
■ Recharge after each use or once a month, whichever comes first.
■ Use only the Physio-Control battery charger designed for use with the
LIFEPAK 500 AED. Do not use any other charger.
