AED Battery FAQ

How long do AED Batteries Last?

The amount of time an AED battery will power your device in standby mode (i.e. without turning the AED on or using it during a rescue) varies by make and model but usually ranges between four and seven years.

How do you check an AED Battery?
  • Check the active battery indicators. Look for a green blinking light or a specific "ready-to-use" symbol. If the light is red or the symbol isn't present, your battery is likely dead.
  • Listen for beeping. If an AED is beeping, it's a sign of a malfunction or low battery.
  • Check expiration dates. Expiration dates are commonly found on each device.
  • If the battery is dead, you can properly dispose of it here.
  • You can also order a replacement AED battery here.
