How do I know when my AED’s battery needs to be replaced?

Your AED Battery may need to be replaced if any of the following occurs:

  • The AED beeps
  • The AED fails self-checks

Our fire department uses Zoll AED Plus’s. Last night we ran a full arrest and shocked the patient 4 times. Wondering if we need to replace batteries, don’t want to wait for an equipment failure.

Hi Bill, We’re sorry to hear the patient didn’t make it. If the indicator on the ZOLL AED is showing a green check-mark then your unit should be fully functional and able to rescue. There are many reasons a patient may not respond to a shock – most having to do with the physiology of the patient’s heart and time from drop to shock. If you feel you should change the batteries, that is done easily enough on the ZOLL AED Plus as it uses 10 consumer Duracell Lithium 123 batteries. They are available for purchase here.

How long does the LifePak 1000 AED batteries last? We’ve had it since 6/12/2019. Luckily we haven’t had to use it. The window indicator has 4 bars and reads OK. Will the bars go down one by one? Should they be replaced routinely?

Hi Sarah,

The LIFEPAK 1000 non-rechargeable battery should be good for 5 years if unused in your AED.
