The engine of your AED: All about batteries and accumulators

The battery is essentially the engine of your AED; it needs to be on standby for years and deliver a massive amount of power within seconds at a crucial moment. Most modern AED batteries are made of lithium, which ensures a long lifespan and stable power output. Depending on the make and model, a battery typically lasts 2 to 7 years.

Automatic self-tests

Did you know your AED checks itself daily or weekly? During these self-tests, the battery status is also accurately measured. If the voltage becomes too low, the device emits a visual or audible signal (such as a beep or a flashing red light). This is the time to take immediate action. Some models even use a separate, small battery for these tests, so the main battery is completely spared for actual use.

Replacement and security

You can almost always easily replace an AED battery yourself by simply clicking out the old one and sliding in the new one. After installation, the device usually performs a self-test automatically.
