You can check the current charge status of a HeartStart XL+ Lithium Ion battery by:
Pushing the fuel gauge button on the battery to illuminate the fuel gauge (see
on page 14). Each light represents approximately 20% of capacity.
Turning the Therapy knob to any position and observing the battery power indicators displayed in
the Status Area (see
Battery capacity diminishes with use and age. Battery calibration ensures the fuel gauge provides accurate
estimates of the charge remaining and it also checks to see if the battery is nearing the end of its useful life
and should be discarded.
Calibrate your battery when the
whichever comes first.
NOTE: Battery calibration can only be done while the battery is installed in the HeartStart XL+ and while in
Service Mode. See the HeartStart XL+ Service Manual for more details. After successfully calibrating your
battery, perform an Operational Check.
Batteries should be rotated regularly to ensure even usage. When storing batteries, make sure the battery
terminals do not come in contact with metallic objects.
If storing batteries for an extended period of time, it is recommended they are stored between
15°C- 35° C (59-95° F). Storing batteries at a higher temperature significantly reduces the battery's life
expectancy. Stored batteries should be charged every 2 months to 20-40% of their full capacity. They
should be charged to full capacity before being put into use.
CAUTION: Do not store batteries in the HeartStart XL+ if the device is out of service for an extended period of time.
Batteries should be discarded if there are visual signs of damage or if they fail calibration. They should be
discarded in an environmentally safe manner.
WARNINGS: Properly dispose of or recycle batteries according to local regulations. Do not puncture, disassemble or
Be careful not to short the battery terminals because this could result in a fire hazard.
