The Philips HeartStart defibrillator battery carries a 4-year Standby life (life while installed in the AED and in standby mode) and 5-year shelf life (new and uninstalled in AED).
The Philips HeartStart M5070a defibrillator battery has the capacity to deliver a minimum of 200 shocks or 4 hours of patient monitoring.
The battery typically lasts 4 years after installation keeping your Philips AED in "ready to use" condition as well as running mission-critical self-tests. Note that using the AED in the course of an emergency rescue or training activity will place a greater drain on the battery and lessen the install life.
