New or recertified defibrillator: is it really worth buying a refurbished AED?

You are shopping for a defibrillator for your company and you come across two devices of the same brand. One is new and costs over $2,000. The other is recertified and sells for much less.

The difference is attractive, especially if your budget is limited.

But a doubt sets in: is a defibrillator that has already been used really reliable? What is its remaining lifespan? And why does it cost so much less?

These are very relevant questions. After all, you don't buy a defibrillator the way you buy a computer or office furniture. You want to be certain you can count on it when an emergency occurs.

So, let’s look at what really distinguishes a new device from a recertified model.

What is a recertified defibrillator?

A recertified AED is a device that has already been in circulation and has undergone inspections before being put back on sale.

It may come from an organization that has renewed its equipment or from another trade-in program.

Depending on the supplier, the process may include functional testing, verification of the device's general condition, and the replacement of certain components.

But be careful: the term "recertified" does not guarantee that all sellers apply the same procedures.

Before buying, you must therefore ask what has actually been checked and what warranties come with the device.

A recertified defibrillator is not necessarily a device refurbished by the manufacturer itself.

Is a recertified AED as reliable as a new AED?

A recertified AED that has been properly checked can be a valid option.

On the other hand, it would be misleading to claim that it automatically offers the same remaining lifespan, the same warranty, and the same conditions as a new device.

Let's take an example.

Two companies each buy a defibrillator.

The first chooses a new model with a manufacturer's warranty. The second chooses a recertified device at a significantly lower price.

Both devices may be functional and meet the needs of their users. But the second one could have a shorter remaining usage life and a different warranty.

This is why price should never be compared without taking into account the age of the AED, its condition, and the terms of sale.

What are the differences between a new AED and a recertified AED?

How much can you save with a recertified defibrillator?

The savings depend on the model.

For example, Cardio Choc lists a Philips HeartStart OnSite HS1 Encore Series at $999. An equivalent new device can cost considerably more.

For a small business or community organization, this difference can make purchasing an AED much more accessible.

But before concluding it's the best deal, you must check the included accessories.

Are the electrodes new? What is their expiration date? How many years are left on the battery? What warranty comes with the device?

A lower-priced defibrillator might require replacing consumables sooner.

This is not necessarily a problem, as long as these costs are known in advance.

What are the risks of buying a used AED?

One must distinguish between a device recertified by a specialized supplier and an AED bought secondhand from an individual.

In the latter case, it can be difficult to obtain reliable information about its history.

For example, a device found on a classified ads platform might look attractive at $500. But do you know if it has already been used? If it has been dropped? If its components are still available?

You must also check if the model is authorized for sale in Canada and if it is subject to a recall or corrective action.

Before buying a used AED, ensure you can get clear answers about its condition and compliance.

Price should not be your only guarantee.

How to recognize a good recertified defibrillator?

Here is what we recommend you verify:

• The recertification process: what tests were performed?
• The age of the device: what is its manufacturing date and remaining service life?
• Consumables: what is the expiration date of the electrodes and the battery?
• The warranty: what does it cover and for how long?
• Accessories: does the device come with everything necessary for its use?
• After-sales service: will you be able to easily find replacement parts and obtain support?

A specialized supplier should be able to explain to you what is included and what is not.

When to choose a recertified defibrillator?

Recertified units can be particularly interesting for organizations with a limited budget.

Think of a community organization, a small business, or a sports association that wants to install an AED without having to invest several thousand dollars.

It can also be a solution to explore when an organization needs to equip multiple sites.

At Cardio Choc, the Encore Series includes various recertified devices from brands like Philips, ZOLL, HeartSine, and LIFEPAK.

Models and stock can vary, but this range offers an alternative to purchasing a new defibrillator.

When is it better to buy a new AED?

If your priority is obtaining the longest potential usage life, a full manufacturer's warranty, or the latest technologies, purchasing a new AED is worth prioritizing.

It is also an option to consider for organizations that wish to standardize their equipment with a specific model or that need particular functionalities.

However, one should not rule out a recertified device simply because it has already been in circulation.

What counts is knowing exactly the condition of the device you are buying.

A new defibrillator and a recertified defibrillator can both be good choices, provided that their characteristics, condition, and terms meet your needs.
