The $10 here, $15 there that you’d spend on disposables really adds up. But the truth is, you can recharge batteries hundreds if not thousands of times. 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.
