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 3 to 7 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 put out 1.5 volts of energy, while NiMHs put out 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.
