Philips HeartStart Defibrillator Battery

The long-life lithium battery typically lasts 4 years installed, keeping your Philips AED in a "ready to use" condition as well as running mission critical self-tests. Using the AED during an emergency rescue or training activity will place a greater drain on any HeartStart AED battery, lessening the install life. This AED battery has the capacity to deliver a minimum of 200 shocks or 4 hours of patient monitoring. Philips HeartStart defibrillator replacement batteries include a 4 year warranty and 5 year shelf life. Philips, No Substitute.
