From our initial tests, they’re quick to charge and very effective in some devices, but you might still want to wait for the technology to mature. The biggest manufacturers – Panasonic, Duracell, EverReady, Varta – don’t seem to be in any rush to put Lithium products out there, so it means taking a punt on a smaller brand. However, they come with a steep price premium and require their own chargers, while the running times with high-voltage devices isn’t usually up there with the best AAs. Lithium batteries are even better at maintaining a consistent voltage, and they are now available at AA sizes. The voltage of Alkaline batteries tends to taper off while they’re being used.īest battery charger 2023: Recharge your AA, AAA and 9V batteries ![]() They’ll also do so more efficiently because the voltage of a NiMH battery is maintained at 1.2V for most of its operating time. These batteries cost only a few pounds more to buy than disposable alkalines and yet they’ll power most devices for longer. Most of the batteries featured here are of the nickel-metal hydride variety, or NiMH.

What’s more, the old memory effect, where failing to use a battery's full capacity before recharging it would see that capacity reduced, is no longer an issue. High capacity rechargeables are increasingly the norm, and they can now hold a charge for a year or more in storage. Whether you’re powering a camera, a torch, a toy, a console controller or remote-control car, a decent set of rechargeables is easily the most efficient way to do it. What’s more, even the upfront cost is now pretty low. Modern rechargeables are reliable, hold their charge and are faster to recharge than ever. Some of these companies make perfectly serviceable cells as well, and others appear to be prone to outright intentional misrepresentation, such as absurdly (and impossibly) inflated capacity ratings and advertised-but-missing features like protection circuits.Low costs and recycling schemes can make disposable batteries attractive, but rechargeables are still the way to go if you want to keep costs down while reducing your environmental impact. This list includes names like GTF, GTL, TrustFire, and Efest. The names on this list might be familiar to anyone who's shopped for high-drain 18650 cells in the past, but all of these also produce batteries in the AA form factor. They don't come close to the ratings, and they show incredibly steep capacity drop-offs even at the smallest loads. These rechargeables are often rated as high-drain with high (often fraudulently so) Ah capacity ratings. Rather than listing a bunch of low-profile brands (like UltraFire) with the same set of problems, we're grouping these together as well. ![]() Those two things are functionally equivalent. The 14500 is a whole class of batteries, and dozens of brands, that are either terrible or are counterfeited so frequently that attempting to buy one leaves you with a terrible battery. ![]()
