AED Electrode Pad Frequently Asked Questions

How do I dispose of my AED electrode pads when they expire or have been used?

AED electrode pads are non-toxic and can be disposed of in regular trash receptacles.

Where are adult AED electrode pads placed?

Two-piece adult electrode pads are placed with one pad on the upper right chest and one pad on the lower left rib cage. All AED electrode pads have a visual representation on the pads themselves to show you where to place them.

The ZOLL AED CPR-D-padz: ZOLL Medical has a one-piece adult electrode pad which uses a cross-hair center piece to help you align the pads properly. This center piece also gives real-time CPR feedback on compression depth.

Where are AED electrode pads placed on a child or infant?

For children under 55 lbs, pediatric electrode pads are recommended. In most cases, one electrode pad would be placed in the middle of the child’s chest, and the other in the middle of the child’s back. Apply according to the visual representation on the pediatric electrode pad packaging.

If your AED has an infant/child key, insert this key in the AED and use the normal electrode pads as instructed.

Do AED electrode pads expire? If so, why?

Yes, all AED electrode pads expire. Electrode pads contain an adhesive, a conducting gel, and a metal electrode. These components can break down over time and manufacturers cannot guarantee the pads will function properly in an emergency past the expiration dates listed on the packaging. It is important to be sure the electrode pads stored with your AED have not exceeded their expiration date.

Expiration dates are found on the AED electrode pad packaging and are intentionally made easy to identify.

What is the shelf life of AED electrode pads?           

The shelf life of AED electrode pads varies by make and model. Shelf life ranges between two and five years. Check your owner’s manual or download our Ultimate Buyer’s Guide and review the Comparison Chart, which lists each AED and its unique attributes such as electrode pad and battery lifespans.

How much do AED electrode pads cost?

Adult electrode pads are priced anywhere from $38 to $225 per set, and pediatric electrode pads cost between $95 and $209. Cost depends on the AED make and model. Pediatric pads are more expensive because they typically contain an attenuator to adjust the energy levels down to those safe for children under 55 lbs.

Should I have more than one set of AED electrode pads with my AED? If so, why?

Keeping a spare set of electrode pads on hand with the device is recommended for two reasons:

  1. If the electrode pads accidentally get compromised during a rescue: The adhesive on AED electrode pads is exceptionally strong, and if the pads slip or are dropped, they may pick up lint after getting stuck to clothing or carpet, pick up dirt and debris from the chest or ground, or there may be a large amount of hair on the patient. This could lead to the electrode pads not adhering to the chest enough to work properly. Since mistakes understandably happen in high-stress situations, having a spare set ensures there is a backup should one of these scenarios occur.
  1. If another rescue needs to take place before the first set of electrode pads has been replaced, having a backup set of electrode pads will allow the rescue to proceed.

AED Battery Frequently Asked Questions

How much do replacement AED batteries cost?

Replacement AED batteries cost between $35.95 and $427, depending on the make and model of your AED.  

What kind of batteries does my AED take?              

Most AEDs use manufacturer- and model-specific lithium batteries. To determine which battery your AED needs, visit our AED Accessories page and select your AED make and model. The manufacturer-approved batteries are listed with the devices.  

One exception is the ZOLL AED Plus, which uses ten consumer lithium 123A batteries. These batteries can be purchased online or at most major retail outlets who carry batteries. All ten batteries should be replaced at the same time. ZOLL also specifies the use of Duracell, Sanyo, or Varta batteries only. AED Superstore also sells these batteries.

In the case of the Physio-Control LIFEPAK CR® Plus and Physio-Control LIFEPAK EXPRESS® AEDs, these devices have an internal battery which is trickle-charged using a CHARGE-PAK charging unit that’s sold together with new electrode pads.

Should I have a spare battery? If so, why?

Having a spare battery gives peace of mind your AED will be able to function during a rescue in the event of a cardiac incident. The worst time to discover your battery has expired or is depleted is in the middle of a rescue. Storing a spare battery with your AED ensures you can quickly insert the replacement and continue the rescue with little interruption.  

How do I dispose of my AED battery when it expires or has been depleted in use?

Most AED batteries contain lithium and must be disposed of properly and in accordance with the customer’s local regulations for disposal of hazardous materials. Some municipalities may have a hazardous material recycling center or have a special hazardous material disposal day for the community.

Battery stores such as Batteries Plus may be able to take a used lithium battery as well. Batteries Plus does not charge for recycling of a non-rechargeable lithium battery. This option is for the disposal of one or two batteries.

As an alternative, AED Superstore will recycle any AED/defibrillator batteries sent to us (whether they are rechargeable or non-rechargeable).You are responsible for any shipping charges related to sending the batteries to us, but we will cover all costs to recycle your batteries. For more information, visit our Battery Recycling page.

What is the shelf life of AED batteries?

The amount of time an AED battery will power your device in standby mode (i.e. without turning the AED on or using it during a rescue) varies by make and model but usually ranges between four and seven years. Check your owner’s manual or download our Ultimate Buyer’s Guide and review the Comparison Chart which lists each AED and their unique attributes such as electrode pads and battery lifespans.

What is the difference between an expiration date/install by date/manufacture date on the battery?

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

Batteries that have 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.

How do I know what kind of date is listed on my battery?

The following symbols can be found on the batteries themselves:

                                                                   

Manufacture Date –   

     

Install by Date –     

Expiration Date –   

How do I check my AED battery to make sure it’s still working? How often do I need to check?

Your AED will perform self-tests to ensure it’s in working order. Depending on the model, it may beep or do something else to alert you when it needs service. You don’t need to actively test or monitor the AED to make sure it’s working. Turning the AED on and off just to check it can drain the battery unnecessarily. Just be aware of when it’s giving a visual or audio alert that it needs maintenance.

How do I know when to replace my AED battery?

It depends on the model, but the AED will typically beep or have a status light or indicator that tells you when the battery is low and needs to be replaced. Your AED will also fail its self-checks.

Is my AED’s battery rechargeable, or can I get a rechargeable battery?

It depends on your make and model of AED whether a rechargeable battery is available. However, we suggest you read our article on rechargeable vs. non-rechargeable batteries. Unless you’re in an environment where your AED is going to get a lot of use, you’re probably better off with a long-life, non-rechargeable battery.

Hello
We have multiple of Cardiac Science AEDs in our Oil Xploration field and various process plants; most of the time we come to know about battery expiry in a short notice and it is difficult to ge the item shipped here as air freight is not possible. We would like to keep some spare batteries in stock so as to use them as and when required; kindly advise the shelf life of batteries( if un used)

Non-rechargeable Cardiac Science batteries have a shelf life of 5 years from the date of manufacture before installing in an AED. If the battery is then installed in the AED on or before the install by date the battery will last for its specific warranty period (warranty varies depending on battery part number and AED model).

How long can the AED pads be left on a patient or after how many shocks do they Ned to be replaced? Phillips heart start machine

The AED electrode pads should be left on the patient until they are removed by a medical professional (EMT, Paramedic, Nurse, Doctor). There is no limit to the number of shocks. However, the electrode pads will need to be replaced once the rescue attempt has concluded. It is a good idea to have an extra set of electrode pads on hand in the event the AED is needed before the replacement electrode pads arrive.

Are there any service providers that will maintain your “fleet” of AED devices? I’ve not been successful locating any. The closest I found is a primarily a tracking & reminder service.

AED maintenance is simple: You check the expiration date on the electrode pads and note the installation date of the battery. From there, you check the AED’s status indicator every couple weeks and make sure it is green (and not red), and that the AED is not chirping (which indicates a problem). A tracking/reminder service, like our ARCH Medical Direction (https://www.aedsuperstore.com/medical-direction-and-oversight.html) will help keep track of expiration dates and send you a reminder to check your AED and let you know when it is time to replace the electrode pads and/or battery.

I have a question on the Legal Liability. Is our Church liable if someone dies after using the AED?

Every state has “Good Samaritan” laws which will protect the user as long as the AED has been used in good faith. You will want to check your state’s Good Samaritan laws for the particulars, as some laws do require specific standards be met for compliance.

If the pads get opened before they are needed are the pads still good

When electrode pads are opened and exposed to the air the conductive gel inside the pads can dry out, rendering them unfit for use. Opening the package before they are needed could also have a negative impact on the adhesive on the pads, which is necessary to provide good contact with the skin. So, unfortunately, if the package has been opened, it will be necessary to replace them as soon as possible.
