Why Replacing Defibrillator Batteries Matters
Like many battery-powered devices, Automated External Defibrillators (AEDs) require replacement batteries at regular intervals. Some AEDs feature rechargeable batteries that are charged using a compatible charger, but most models use non-rechargeable lithium-ion battery packs.
Replacing your defibrillator’s battery before it expires is a crucial part of defibrillator maintenance, ensuring your AED remains active and ready for use. Batteries have an expiry date printed on the unit and/or packaging, which indicates the replacement interval. This is usually 4–5 years depending on the model, unless your AED indicates a battery issue during a self-test.

How long do defibrillator batteries last?
Defibrillator batteries normally come with a 4-5 year expiration. This is because the battery capacity depletes over time, especially if the defibrillator is used in an emergency. It’s important to replace your defibrillator battery before the expiry date to avoid gaps in operational readiness, and keep your AED available for use 24/7.

Do I still need to replace the battery if the AED remains unused?
Yes. Replacing your AED’s battery is important regardless of whether or not it is deployed in an emergency. The battery capacity slowly declines over time, including when the defibrillator is left unused in storage. If your defibrillator’s battery is nearing its expiration date, it’s time to order a replacement.
