What is the date on my AED Battery?

The date shown on an AED battery can be: 

  • A manufactured date
  • An install-by date
  • or an expiration date.

Batteries that contain an expiration date should be used and properly disposed of on or before the expiration date listed.

Batteries that contain a manufactured or install-by date should provide power to your AED for a specific number of years (which varies by brand) from the date the battery was installed in your device.

Helpful hint: For batteries that use a manufactured date or install by date, use a permanent marker to write the date when you installed the battery into the AED. Doing this will allow you to later cross-reference the estimated expiration date and not be forced to remember when you installed the battery years after the fact. Contact us to learn more about how we can use software to help track all of the important expiration dates for your AED program or if you’d like to get answers to your unique situation.

Hello there,
Our Phillips AED 502861 equipped with spare battery showing Install-by date Oct 2020,
Would it consider expired if we do not install it before Oct 2020?
What if we install it before Oct 2020, for instance we install on 15th Sep 2020, should we replace again on Oct 2020 or battery still good until the flash light become weak?

Hello Rendra!
Philips HeartStart defibrillator batteries (M5070a) include a 4-year warranty and 5-year shelf life. The battery typically lasts 4 years from the time it is installed. If you install it on or before October 2020, it should last 4 years (Until October 2024) provided the AED remains well maintained and unused. Batteries should generally be replaced in the event it is used in a rescue.

I was in charge of keep all our companies AED’s accounted for and inspected on a monthly basis.
This was a couple of years ago and I have since been tasked once again with monitoring the AED program.
We currently have about 55 AED’s at 3 different locations. All of our AED’s were previously registered on your program.
When I went to log in, (once again after a couple of years) in asked for my email and password. I did not remember my password and hit the forgot password button, but the program didn’t recognize my email.
Not sure where to go from here, but I could use some help.

I installed a Philips Heartstart battery in one of our defibrillators on February 15, 2022; it is showing a “Install before 2026-05” date and it has already gone bad and is constantly beeping. Who honors the four (4) year warranty? can you please advise?
