Defibtech AED Batteries

Defibtech replacement batteries for the Lifeline AED series give you flexibility on lifespan — and keep your device on its full self-testing schedule between uses. The standard Lifeline offers two battery options: a five-year pack and a high-capacity seven-year pack, both using a 9V lithium battery with a simple click-to-replace installation. For the Lifeline VIEW, a four-year replacement battery pack keeps the device powered and running its full self-testing schedule. All batteries support the Lifeline's daily, weekly, and monthly self-tests, and each provides audio and visual low-battery indicators so you know well in advance when a replacement is due.

Battery lifespan ranges from four to seven years depending on the model you choose. Matching the right battery to your device ensures your AED stays on its self-testing schedule and is never caught off guard by an unexpected power failure.
