If you recharged the batteries just once, you’d save money. One major brand, for instance, sells a pack of eight single-use batteries for $22 and rechargeables (with charger included) for $30. Price: Overall, rechargeable batteries are a better buy than disposables-and you start saving right away. Conversely, lithium batteries should be repowered in their manufacturer-specific chargers. Many have a flip-down AC jack that plugs directly into an AC power outlet. Lithium batteries have the slight edge on retaining power during multiple recharges, while NiMH batteries hold their charge longer when left unused.Ĭharger Considerations: You can typically use a NiMH AA/AAA charger with any brand of battery. Recharge Quality: Both types lose 20 to 30 percent of their might after several dozen recharges or when you don’t use them for a while. For quick turnaround, lithium wins hands down. Recharge Time: It takes three to seven hours to recharge a NiMH battery, while a lithium one fully recharges in an hour or two. Motorized products, from remote-control toys to electric toothbrushes, run better on lithium. Lithium batteries have the advantage in devices where power supply is key. Performance: Lithium batteries output 1.5 volts of energy, while NiMHs output 1.2 volts. That’s why they are perfect for TV remote controls, wireless keyboards, digital cameras and camera flashes, wall clocks, and video-game controllers. NiMHs also retain their power better when they’re sitting idle on a shelf. Longevity: NiMH batteries generally outlast lithium ones. In 2020, a handful of Chinese companies started selling a rechargeable version of lithium batteries. NiMH batteries are more popular and have been around a while. Rechargeable AA and AAA batteries come in two main types: nickel metal hydride (NiMH) and lithium. What to Look For With Rechargeable AA and AAA Batteries I have reviewed and used many rechargeable AA and AAA batteries over the years. I’m also a judge for the Consumer Technology Hall of Fame. News & World Report, CNET, Rolling Stone, and Sound & Vision. The Expert: For nearly 40 years, I've been reviewing consumer technology for publications including U.S. Best Large Capacity Battery Charger: Tenergy TN438 16-Bay NiMH/NiCAD AA/AAA Charger.Best AAA Batteries for Motorized Devices: AmpTorrent AAA Lithium Batteries with USB Charging Cable.Best AA Batteries for Motorized Devices: Tenavolt AA Lithium Batteries and Charger.Best AA Batteries for Video Game Controllers: Duracell Rechargeable NiMH AA Batteries.Best AA Batteries for Toys: Amazon Basics Charger and NiMH Batteries.Best AAA Batteries for Remote Controls: Deleepow AA/AAA LCD Smart Charger and NiMH Batteries.Best AA Batteries for Remote Controls: Energizer AA/AAA Recharge Pro Charger and NiMH Batteries.Longest-Lasting AAA Batteries: Panasonic eneloop AA/AAA NiMH Charger and Batteries.Longest-Lasting AA Batteries: Panasonic eneloop AA/AAA NiMH Charger and Batteries.Best Value Batteries: Tenergy Premium PRO NiMH AA/AAA Batteries.When it's time to get your gadgets going again, these are the rechargeable batteries worth your money. While there is a bigger cost initially, rechargeable AA and AAA batteries-depending on the brand-can be juiced up hundreds of times ultimately saving you money and saving Earth. If you opt for single-use disposable batteries there are two negatives: the cost of repeated replacement purchases and electronic waste-dead batteries ultimately end up in a landfill.Īn option that is more appealing for the environment and your wallet is rechargeable batteries. Sadly battery marketing is an evil game, with overstated capacity being the industry norm.Think about the household devices and tech gadgets you use on a daily, weekly, or even monthly basis that require AA or AAA batteries- TV remotes, video doorbells, alarm clocks, children's toys, game controllers, cordless phones, smoke detectors, blenders, electric salt and pepper mills, handheld mixers, and the list goes on. We guarantee our cells are true to their capacity! Normal NiMH batteries would lose nearly 100% of their charge over 12 months. In fact, these LSD batteries can stay charged for over a year without losing more than 30% of their charge. Low-Self-Discharge NiMH batteries are a new technology that prevents the battery from slowly losing its charge over time. Many battery applications are compatible with NiMH rechargeable batteries, however, they are best-suited for vehicles that require large amounts of energy and are frequently used. NiMH batteries are rechargeable and are fantastic for commonly-used or high-drain devices. Great for remote devices, camera, transmitters, or other low discharge electronics that you want to use over several months or years without having to recharge.
