Battery Testing and Troubleshooting
A HeartStart XL+ battery is suspect if you do not know when it was last checked.
To test a suspect battery:
1 Check the battery's fuel gauge.
2 If fewer than two battery fuel gauge LEDs are on, then partially recharge the battery:
a Insert the suspect battery into the HeartStart XL+.
b Connect the HeartStart XL+ to an AC power source.
c On the HeartStart XL+, make sure the green AC Power indicator is on and the battery charging
indicator is flashing.
d Turn off the HeartStart XL+ and charge for 20 minutes.
3 Remove AC power and turn the HeartStart XL+ on.
If the HeartStart XL+ shuts down immediately or does not turn on, then the battery is faulty.
4 Attempt a shock using the Defibrillator Test Plug (Select the 150 J energy, charge, and shock).
If the HeartStart XL+ shuts down or restarts, then the battery is faulty.
5 Test the battery fuel gauge.
If at least one battery fuel gauge LED lights steady, then charge and use the battery as needed;
calibrate as soon as possible. Otherwise the battery is faulty.
Sometimes improper wiring inside the HeartStart XL+ box may cause a battery connection problem. If
you suspect a battery connection problem, inspect the battery connector in the battery compartment.
The pins must be clean and not bent, and the connector should sit comfortably in the opening and
“float” slightly when pressed sideways. If the connector is skewed to one side of the opening and does not
float, then check for pinched wires inside the Rear Case. See “Opening the Case” on page 87 and
“Closing the Case” on page 151.
Tab le 1 0 and Figure 33 on page 49 discuss the battery problems that can occur. The messages may
appear in the Technical Alarm or Battery Status area of the HeartStart XL+ screen, as shown in Figure 30
on page 43.
