Philips HeartStart FR2 and FR2+ Battery M3863A Benefits

  • Durable
  • Cost-effective

Every effective AED needs a dependable AED (automated external defibrillator) battery. The Philips HeartStart FR2 battery is just that- dependable- so you won’t be left with a dead battery during an incidence of Sudden Cardiac Arrest (SCA). The M3863A Philips battery is made to be the replacement battery for the Philips HeartStart FR2 AED and the Philips HeartStart FR2+ AED.


The Philips FR2+ battery has a 300 shock capacity, which equates to 12 hours of operating time. When the HeartStart AED is rescue ready, its battery will be operable for a minimum of 4 years and comes with a warranty. Rescue ready means that the AED battery is inside of the HeartStart FR2 AED on standby. The M3863A battery is rescue ready when its AED’s LCD screen flashes an hourglass symbol. The AED will indicate if the battery is low by flashing a red X. If the AED shows a solid red X, this means the battery is completely dead and needs to be replaced immediately.

Every AED defibrillator should remain rescue ready with its battery left inside of it to be prepared for a medical emergency. During SCA every second counts. That’s why it’s critical to maintain all components of an AED. It’s highly suggested to carry a replacement battery right beside every AED in case the primary battery malfunctions during a medical emergency. If the M3863 battery is left outside of the AED and used as a secondary battery it has a 5 year shelf life.

The FR2 battery can be manually tested by removing the battery from the AED and then reinserting it. Once the Philips M3836A battery has been reinserted, an LCD screen will appear. On the LCD screen, there will be a NEXT button. After pressing the NEXT button, choose BATTERY HISTORY.


The Philips HeartStart FR2+ battery is a cost effective solution to maintaining the safety of your Philips HeartStart AED. The M3863A battery comes with free shipping and a 30 day money back guarantee. If you’re not satisfied with our product, we want to know! Remember, AED electrode pads have expiration dates and also need to be replaced.
