Do AED Batteries and Pads Expire?

Yes they do, but how long do AED batteries last?

  1. Fortunately, most AED batteries last anywhere from two to five years in standby mode.
  2. For the most accurate information regarding your AED model, refer to your user manual.
  3. Expiration dates can also be found on the back of your AED battery.
  4. Typically, an AED battery will have three dates printed on it: 1. a manufactured-by date, 2. an install-by date, and 3. an expiration date.
  5. An AED battery should be used within five to seven years of its manufacturer date.
  6. The install-by dates indicate that the battery should be installed in an AED no later than the specified date.

The expiration date indicates when the battery will no longer function.

We recommend having a replacement battery ready and accessible at all times.

Some AED batteries will need to be replaced after use, others are capable of handling multiple rescues. Refer to your owner’s manual for more detailed information.

Like AED batteries, the shelf life of AED pads varies. Most pads, however, have a shelf life of two to four years. The water-based electrolyte gel that sticks to the chest of the victim and conducts electricity dry out over time, so both the pads that are attached to the AED, as well as the backup pads, should be routinely checked and replaced as indicated.

Pads should always be replaced after use.

If you’re concerned about keeping track of expiration dates, consider a compliance management program Like the U-Tech Medical Compliance Management System.
