Energizer AA Batteries, Ultimate Lithium, 4 Pack Double A Battery Pack

Product Information

No one else tests like Which? – our independent lab tests simulate the way you really use batteries, so you can be confident that our Best Buy AA batteries will power your devices for longer.

We’ve compared Energizer, Duracell and Panasonic batteries with supermarket own-brand batteries, such as Aldi, Morrisons, Lidl and Sainsbury's, to find the very best. Best Buy AA batteries on test For high-drain devices, low-cost batteries may only be fractionally cheaper per hour of intensive use than some of our Best Buys. When the latter will last longer, is the extra hassle of buying, replacing and recycling them more often worth such a small saving? Best AA batteries for 2023In many cases, yes. rechargeables don’t deliver as much voltage as disposables (typically 1.25V rather than 1.5V), but they normally maintain the same level for longer and can just be recharged when they run dry. You pay more upfront for the batteries and the charger (if you need one), but you’ll recoup the difference within a couple of uses – and AA batteries cost so little to recharge that it’s barely worth thinking about. Factor in the clear environmental issues and it’s a no-brainer, although many local councils and some supermarkets now offer free recycling. 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. Leak-resistant and boasting a shelf life of as long as ten years at room temperature, Ultimate AA/LR6 Energizer cells deliver reliable power. They continue working in extreme heat and cold: the manufacturer-recommended temperature limits are -40°C (minimum) and 60 degrees Centigrade (maximum). Especially useful in portable appliances, the battery weight of 100 grammes is around 30 per cent less than typical alkaline cells. Our Best Buy AAA batteries last an hour and a half longer than the worst batteries on test in high-drain devices and four hours longer in medium-drain devices, like a games console. 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. Should I buy rechargeables instead?

It's not just disposable batteries that be thrown away like this. If you have a lithium-ion battery for a phone, computer, or other electronic device, it can go in the same bin. If it fits in your hand, it's probably fine to go in a shop's battery bin. Shop around for AA and AAA batteries and the main types you’ll find are alkaline and lithium disposable batteries. Each LR6/AA cylindrical cell measures 51 millimetres (height) by 15 millimetres (diameter). Ultimate AA batteries are direct replacements for size codes AM3, E91, FR6, L91, KAA, MIGNON, MN1500, ND62S, R6, UM3 and 4006.We’ve tested batteries from Aldi and Lidl – which can cost as little as 26p per battery – alongside big brands Duracell and Energizer to see how they match up. Only our tests reveal whether buying cheaper batteries will save you money and hassle.

Any shop that sells a certain amount of batteries per year (and the threshold is low) is obliged to have a collection point for old batteries. From here, they will be recycled and the useful chemicals will be extracted.Rechargeable batteries can run for hundreds of cycles, meaning you don't have to buy and dispose of huge quantities of disposable batteries. This is much cheaper and it's better for the environment as well since battery disposal and recycling can be a carbon-intense process. Our tough lab tests have uncovered big differences between the best AA batteries and the worst. Use our results to make sure you don't waste your money. When your batteries are out of juice, the best thing to do is to take them to your local shop and put them in the battery bin there.
