![]() ![]() These devices mean an initial investment that might seem greatly inflated, especially as they necessitate the purchase of a charging unit as well. Their price does make them an illogical choice for many purposes, though.įinally we have the category of rechargeable AA batteries. ![]() Lithium AA batteries are also lighter in weight and have an impressive shelf-stable life measured not in years, but in decades. While notably more expensive than alkaline AAs, these batteries offer much more potential energy than their alkaline counterparts, even running certain electronics for nearly ten times longer than alkaline units. These leaks are not particularly dangerous, though they can be dirty to clean and can damage electronics and hardware.Įver more common these days are Lithium AA batteries. Alkaline batteries are also notorious for leaking "battery acid," which is ironic, for indeed the fluid they may leak is aqueous potassium hydroxide, a basic solution. Many alkaline batteries are only suited for low drain devices like a clock or remote control, for example. Despite their many obvious benefits, including the aforementioned low cost and their reliable long shelf life, such batteries do have drawbacks. Alkaline AA batteries produce a 1.5 volt output that, under most circumstances, will remain steady until the battery's stored energy is depleted. Trusted for decades, these batteries are affordable and effective, readily powering devices ranging from flashlights to cameras to music players and beyond. The first is well-known to all: the single-use disposable alkaline AA battery. From then on, it was only a matter of refining the internal workings of these compact, common sources of energy, and today the modern consumer has three major categories of AA battery from which to choose. By the middle of the 20th Century, the AA size we use today had been fully standardized. But this slender cylinder would prove to be one of the most popular battery sizes ever created. It was only the latest iteration of dry cell battery technology, which had been refined over the course of the 19th Century. The AA battery was first introduced well over a hundred years ago. We were especially pleased to find the cleverly designed Hitrends Rechargeables, which you can quickly juice up from any USB port. Alkaline units cost less in the short run, but rechargeable cells have closed the capacity and shelf-life gap with their alkaline cousins, so our selections include samples of both. The former two are offered in high-quantity packages consider a top-notch battery case to go with them, which will make storing such large quantities much easier.ĪA batteries have become the workhorses of our digital age, powering everything from mice to keyboards to cameras to game controllers, and it is now necessary to have a supply of them on hand. The Survival Frog batteries seem to have a slight edge over the Hitrends model when it comes to durability.įinally, if it's simple alkaline batteries you seek, look to the Rayovac High Energy or the AmazonBasics Performance Alkaline, if the budget is tight, or the Duracell Quantum Alkaline, which are better quality but more expensive. But we've replaced the Hitrends Rechargeables with the Survival Frog EasyPower, a USB choice that's similar to the former. Outside of Panasonic, there remain plenty of other great rechargeable choices, including the perennially popular Energizer Recharge Universal and the wallet-friendly AmazonBasics High-Capacity Rechargeables. Both are available for purchase with or without a charger, and both also come in AAA versions. You should choose the Pro version, then, when high-powered performance is crucial, even if you expect to have to replace them sooner. ![]() The Pro version has a 2,550-mAh capacity to the Eneloop's 2,000-mAh capacity however, the Pro version offers 500 charge cycles, whereas the Eneloop can be recharged up to 2,100 times. Thanks to their reliability, value for the cost, and long-lasting power, the Panasonic Eneloop still come out on top, and we've added the Panasonic Eneloop Pro, as well. ![]()
