I Got the Power! Your AED and Defibrillator Battery Guide

aed and defibrillator battery guide

The first defibrillators used in hospitals were large, bulky machines that could not be easily transported from room to room. Today, AEDs are small enough to fit in a large first aid kit, and defibrillators can be easily carried with EMT equipment or from one hospital room to another. Powered by rechargeable batteries, these devices must be regularly serviced to keep them in working order when you need them.

How Long do Defibrillator Batteries Last?

The defibrillator battery life depends on the brand of device you are using and how often you use it. Some batteries last as long as four years with regular charging while others can last up to five years before they need to be changed out. However, since defibrillators are typically used more than their AED counterparts, many batteries only last two years with regular use. Some defibrillator batteries are even designed to last a certain number of shocks before they need to be charged or replaced while others are designed to be plugged into a wall and trickle charged when they are used for patient monitoring.

How Long do AED Batteries Last?

Since an AED is typically held in reserve rather than used on a regular basis, one of the biggest challenges is making sure it is ready when you need it. AED batteries are designed to last four years with regular maintenance and thorough inspection. Some AED brands last as long as five years. Many even automatically perform regular battery checks that charge the battery and alert users when a battery needs to be replaced. Others rely on a human to test the battery according to manufacturers instructions.

AED Battery Replacement

Replacing a battery on an AED is designed to be a simple process. Depending on the brand, the battery pack is generally located on the back or bottom of the AED and can be removed by pressing a button or removing a clip. Once the battery is removed from the device, simply replace it with a new battery and return the original for recycling or disposal. An AED battery will typically cost between $100 and $300, depending on the brand and can be ordered through Foremost Medical Equipment.

Defibrillator Battery Replacement

Replacing a defibrillator battery is just as easy as replacing an AED battery. The main difference is that defibrillator batteries are typically charged after every use rather than daily or weekly. Many hospitals, clinics, and medical centers have spare defibrillator batteries charged and ready to use in case another defibrillator battery begins to run low during an emergency. Since defibrillators in these settings are typically used more often, their batteries tend to be replaced more regularly than AEDs that standby in case of an emergency.
