With an Ansmann charger ( sold separately for nearly $80), expect the batteries to fully charge in 15 to 20 minutes. However, it does come at a steep price-a pack of eight is about double the cost of other rechargeable batteries on our list. Types Available: AA | Comes Pre-Charged: Yes | Number Included: 8, 12, 16, or 24 | Comes With Charger: No | Charge Cycles: 1000Ĭompared to other options, this is one of the best rechargeable batteries for devices that consume a lot of power, such as DSLRs, power tools, remote-controlled toys, and microphones. Keep in mind that several users found them slightly larger than your average AA batteries-they may be tough to get in and out of your devices. Overall, they have a shelf life of five years which is the maximum life expectancy estimated for a NiMH battery.įor this pick, no charger is included. The batteries have a low-self discharge rate (the rate at which a battery loses charge over time) and are able to maintain 80 percent of their capacity for up to two years. This means that you won’t be throwing them away as often, which in turn is better for the environment. You can recharge them up to 1000 times with minimal power loss. They are pre-charged and can be used immediately out of the box. The batteries have a 2000 mAh capacity, which guarantees that they will go the distance and last a while before recharging. Sold in packs of 8, 12, 16, and 24, they are priced at slightly under $2 a battery.

These batteries are best used in small devices like radios, lanterns, toys, wireless devices, and game controllers. In addition, the battery has an extremely low discharge rate (the amount of energy it releases over time) and is able to stay at 80 percent capacity after three years of non-use. The batteries have a lifespan of 1200 charge cycles which should last a few years, even with frequent use. These are NiMH batteries, meaning they stay charged for longer compared to alkaline batteries. You also get a hard plastic case to store the batteries when they’re not in use. We put them at the very top of our best rechargeable batteries list because they feature a patented technology that helps them reach their max capacity (2800 mAh-milliamps per hour) during the charging and recharging process. We also asked Kelso to explain important terms you should know when buying batteries, plus add some tips for shoppers. We researched the best rechargeable batteries and looked at factors such as the number of batteries in a pack, charge cycles and lifespans, capacity rating, and cost per battery. “Rechargeable batteries are a great way to always have power for your technology devices, and you are helping keep digital waste out of our landfills.” “It’s a great idea to have rechargeable batteries because you could spend a fortune purchasing new batteries for your tech devices,” says Burton Kelso, a consumer and business tech expert and cybersecurity keynote speaker.

Because they can be reused constantly, you don’t have to waste money buying a ton of batteries. Rechargeable batteries are a great alternative to alkaline batteries for running tech devices such as keyboards, mice, and smart TV remotes.
