2. Amazon Basics AA High-Capacity Rechargeable Batteries

One of the best things about AmazonBasics is its high-quality components. Its top safety features provide safe operation for both the device and the user.

Besides, if overworked or used in the wrong way, the short circuit preventive washer (SPW) can protect self-discharging and short-circuiting. Further, it has two small holes to prevent bursting or heat build-up. It is the ideal option for anyone looking for a reliable and safe-to-use battery.

Apart from the high-quality components and huge battery capacity, it can provide a long-lasting shelf life of up to ten years. The battery locks in power and uses the new zinc composition, improved anti-corrosion, and two crimp design to prevent leakages. It is also designed in a well-built liquid-tight seal and a well-built battery’s air to store power, making it an excellent option for anyone looking to use them in an emergency.

3. Duracell-CopperTop AA Alkaline Batteries

While many modern tech gadgets tout sophisticated charging methods (e.g., using solar power), alkaline batteries remain a staple power source for most electronics. Duracell’s CopperTop AA alkaline battery-pack particularly stands out due to its unique construction and long life.

Since it is an alkaline battery rated at 9V, it provides dependable and long-lasting power for high-draining and low-draining devices, including flashlights, toys, remotes, and smoke detectors. On average, alkaline batteries provide 10 for continuous use.

This means a low power device like a wireless keyboard, trackball, or mouse can use the batteries for nine or more months before needing replacement. However, for a single battery LED flashlight, the battery provides a reasonable 1.5 hours of juice.

On the same note, Duracell is all about upholding the safety of your electronic devices by guaranteeing the batteries against defects in craft and material. As such, if any of your gadgets is damaged due to a battery defect, the company repairs or replaces it. And the good news is that the guarantee extends to ten years.

4. Energizer Ultimate Lithium

If you’re looking for a battery that can go the distance no matter the drain, look no further than the Energizer Ultimate Lithium. While 33% lighter than the equivalent alkaline battery, each one packs in a whole lot of charge; even after powering our 500 lumens test torch for 90 minutes they could still deliver 1.48V, keeping it at maximum brightness long after other batteries allowed the light to fade. After a further 90 minutes, we still had nearly 1V on our test meter.

That’s one impressive performance and, with a 20-year storage lifespan and the ability to work in temperatures from -40°C to 60°C, they won’t let you down. Needless to say, you pay for that kind of stamina, with each battery working out at over £1.50.

5. Energizer Alkaline Power

Most of us don’t buy batteries in advance but grab them when we need them, in which case the Energizer Alkaline Power batteries are ideal for everyday use.

They’re often cheap both in supermarkets and online stores, and you can pick them up for around 40p per battery if you buy in bulk. This might lead you to expect sub-par stamina, but the Energizers could surprise you: they were the top alkaline battery at the 60 and 90 minute marks in our tests, although they struggled further on with the voltage falling to just 0.75V after three hours of use, leaving the torch looking visibly near-drained.

Not your first choice, then, for high-drain devices, but if you’re looking to keep a wide range of gadgets in power, this is a great, cheap way to do so.

How to choose the best AA batteries for you

For some purposes – when you’re powering low-drain devices such as a clock or remote control – the differences aren’t that important, but with high-drain devices like a camera, game controller or anything with a lamp, screen or motor, you could see huge differences in lifespan and reliability.

Today’s disposable batteries break down into three basic types:
Zinc chloride: This used to be the general-purpose battery of choice, but alkaline batteries are now so cheap that you don’t often see them. They’re cheap as chips when bought in bulk and fine for low-drain gadgets such as a remote control, but you’ll go through them quickly on anything more demanding.

Alkaline: The mainstream battery technology for high-drain devices. They’re cheap and very easy to find, and last much longer than the old zinc chloride batteries. Technical advances have also seen the major problems – a short shelf life and a propensity to leak – reduced or even fixed.

Lithium: Lithium batteries work even better than alkalines. They last much longer, have an epic shelf life, don’t discharge as much power when not in use and can cope with extreme temperatures. While normal alkaline AAs struggle below 0°C, lithium batteries will operate down to -40°C. They can also be up to 9g lighter than the equivalent alkaline AA battery, which counts when you have something powered by four AAs. The only negative? They’re significantly more expensive.

Generally speaking, you should go for alkalines for most of your battery needs but opt for lithiums for digital cameras or other high-drain products where you need a reliable high charge for as long as possible.


AA batteries are the cream of the crop when it comes to batteries. And although we are in an age where built-in batteries are the modern trend, these batteries are not going anywhere. But as noted, they are not made equal. There several factors to consider when picking which batteries are the best for your unique needs.

The above article is a valuable reference for you to choose a suitable AA battery.
