When To Replace The Battery - Philips HeartStart Home Owner's Manual

WARNING: If you take out the battery and
put it back in more than once when you hear
a pattern of triple chirps, your HeartStart
might seem ready to use, even though there's
a chance it won't be ready to use in an
emergency. If you hear a pattern of triple
chirps from your HeartStart, please call Philips
immediately, unless you're in an emergency
and need to try to use your AED.

WHEN TO REPLACE THE BATTERY

The lithium battery used in the HeartStart
normally lasts for about four years in
standby mode. ("Standby mode" means the
HeartStart is ready for use, with the
battery installed and the green Ready light
22
blinking.) When the HeartStart is turned
on for use, a new battery normally lasts for
4 hours, or can give up to 200 shocks.
After you put the battery in the HeartStart,
the self-test checks it every day. When
battery power gets low, the HeartStart will
start chirping to alert you.
The battery is not rechargeable. Do not try
to open, crush, or burn it. After it is used
up, throw it away in household waste or
according to local regulations.
