AED Batteries

Between 4 and 7 years depending on brand and model. Defibtech's high-capacity Lifeline pack is the longest at 7 years; most others run 4 to 5.

Always go by the printed expiration date on your specific battery rather than a general figure.

We stock genuine OEM batteries only. Manufacturer warranties generally depend on using OEM parts, and an AED battery is not a component worth economizing on.

An underperforming battery may still pass a self-test yet lack the capacity to deliver a full rescue.

Yes. It runs on ten 123A lithium cells, the same type sold for cameras and flashlights, rather than a proprietary sealed pack.

No other AED brand we stock does this. Always use fresh, in-date cells. See the ZOLL AED Plus.

HeartSine builds the battery and electrodes into a single Pad-Pak cartridge with one expiration date, so you replace both together every four years.

For a program managing several devices, that halves the number of dates you are tracking.

The Defibtech Lifeline 7-year high-capacity pack, rated for 300 shocks or 16 hours of operation.

The standard Defibtech pack runs 5 years, and most competing brands run 4 to 5.

Yes, along with the pads, regardless of the printed expiration date. A rescue draws significant capacity and the remaining charge cannot be reliably assessed.

Replacement AED pads are single-use and must be replaced after any deployment.

TSO certification qualifies equipment for use aboard commercial aircraft. Both Cardiac Science and HeartSine offer TSO-certified options.

Standard batteries do not carry that certification. If your AED flies, you need the certified version.

Most modern AEDs run automatic self-tests and show a visible status indicator or audible alert when battery capacity drops.

Treat that as a backstop, not a plan. Track the printed expiration date and replace on schedule instead of waiting for an alert.
