Defibrillator Accessories: Choosing AED Electrodes and Batteries
- 4 min reading time
Four accessories determine whether an AED is ready for use: model-specific defibrillation electrodes for adults, paediatric electrodes or a child key where needed, a battery that has not expired, and clearly visible storage. Electrodes and batteries are manufacturer-specific and have expiry dates. Buyers should therefore know the exact model designation of the device before every order.
An AED is only reliably ready for use when its accessories are current and compatible. This article shows what to consider when selecting, reordering and storing defibrillator accessories. The instructions for use and the specifications of your device's manufacturer always take precedence.
Defibrillation electrodes: adults and children
Defibrillation electrodes, often called pads, are single-use products. They are replaced after every use and, even if unused, no later than the printed expiry date. Connectors, cables and gel coating differ between manufacturers, so electrodes usually only fit certain device models.
For children, there are different solutions depending on the device:
- Separate paediatric electrodes: dedicated pads connected instead of the adult electrodes.
- Universal electrodes with child mode: one set of pads for all age groups, with the mode switched via a button or key.
The manufacturer specifies in the instructions for use which age group or body weight the paediatric solution is intended for. If children belong to the group of people who may need it, for example in paediatric practices, schools or sports clubs, order the matching solution at the same time.
Batteries: standby life, expiry date and storage
AEDs mostly use non-rechargeable lithium batteries built specifically for each model. Manufacturers state two values: the standby life and the capacity in shocks or minutes of use. Automatic self-tests also consume energy. The device's status indicator shows when the battery needs to be replaced.
On some models, battery and electrodes are combined in a single cartridge. This simplifies replacement, because both components share the same expiry date. Store spare batteries dry, in their original packaging and within the temperature range specified by the manufacturer.
Standard batteries, for example for alarmed wall cabinets or other practice devices, can be found in the batteries category. The AED battery itself, by contrast, is ordered model-specifically from the defibrillator accessories.

Compatibility and reordering: how to avoid wrong orders
The most common cause of wrong orders is an imprecise model designation. Many manufacturers sell several device generations with similar names whose electrodes and batteries are not interchangeable. Always use only accessories that the manufacturer has approved for your model.
Reordering checklist:
- Manufacturer and exact model designation noted from the type plate
- Article numbers of the previous electrodes and battery at hand
- Expiry dates of all components recorded in a maintenance plan
- Need for paediatric electrodes or child key checked
- Several devices of the same type combined in one order
- Date for the next replacement scheduled with enough lead time

Storage, wall bracket and carry bag
An AED should be quick to find and easy to reach. A wall bracket or wall cabinet marks the fixed location, and alarmed cabinets signal when the device is removed. For outdoor areas there are weatherproof cabinets, some with heating. A sign according to ISO 7010 (symbol E010) marks the location in a standard way.
For mobile use, for example on home visits or in vehicles, a carry bag protects the device. Suitable bags and backpacks can be found under emergency bags and backpacks, and CPR masks complete the rescue kit. How to choose the device itself is explained in our AED buying guide.

Frequently asked questions
How long do AED electrodes last?
The expiry date is printed on the packaging and is usually several years, depending on the manufacturer. After every use, the electrodes are replaced regardless of the date.
How long does an AED battery last?
According to manufacturers, the standby life is usually several years. It depends on self-tests, uses and storage conditions, among other things, and the status indicator shows when replacement is due.
Are special paediatric electrodes needed?
Many devices provide separate paediatric electrodes or a child mode. Which solution applies to your model, and for which age group, is stated in the instructions for use.
Do electrodes from other manufacturers fit?
Usually not. Only use electrodes and batteries that the manufacturer has approved for your exact model.
