AED's (Defibrillator) Batteries

Defibrillator Battery Replacement for AEDs

When do I need a defibrillator battery replacement?

A defibrillator battery needs replacement when your AED battery shows a low battery warning. AED batteries are designed to last for a set period, but they should still be checked regularly as part of your routine defibrillator maintenance.

If the battery is low or showing a warning, it should be replaced as soon as possible. Keeping a spare AED battery on site can help make sure your defibrillator stays ready for use, especially in schools, workplaces, sports clubs and community locations.

Which AED battery do I need?

AED batteries are usually model-specific. Before ordering, check the brand and model of your defibrillator, then match it to the compatible battery listed on the product page.

Using the wrong battery may stop the device from working correctly, so it is important to choose carefully. If you are unsure which AED battery fits your defibrillator, contact our team, and we will help you find the right match.
