How we selected the best rechargeable batteries

In order to select the best rechargeable batteries, we looked at several different scenarios and concerns, and examined impressions from both professional and personal users. The methodology strived to identify products designed to be the longest-lasting with the most minimal impact on the environment. We worked to identify batteries that could spring into action even when stored in a drawer for years, as well as options that come equipped with the latest conveniences, like USB charging that can be done directly to the battery with any compatible cable instead of using a more inconvenient apparatus.

What to consider when shopping for the best rechargeable batteries

When you’re considering what the best rechargeable batteries for your needs will be, take a moment to think practically about what sizes and quantities you should have for all the battery-powered gear that you keep around the house, in the garage, in the car, etc. Note how many charge cycles are associated with the product you want to purchase. You may also think about if you want to get a small or large charger to go with your rechargeable batteries, depending on how many you need at once, or if you want to just buy a brand of rechargeables that have USB ports right on the batteries, so you can use any USB charger to give them a jolt.

Do rechargeable batteries come already charged and ready to use?

Some rechargeable batteries come pre-charged, while others need to be charged before using for the first time. Pre-charged rechargeable batteries are usually labeled as such on the package. If you don’t pick up pre-charged batteries, consider whether you have an appropriate charger at home or whether you should pick up a starter kit that includes one.

Can I mix single-use and rechargeable batteries in the same device?

While you might get a device to technically work with a mix of single-use and rechargeable batteries, it’s better to avoid mixing and matching these different kinds of batteries. Regular batteries and rechargeables output slightly different volts of energy—the former uses 1.5 volts, while the latter uses 1.2 volts. There’s another key difference between the two: regular batteries start outputting at 1.5 volts and that number decreases until the battery dies, while rechargeable batteries stay consistent at 1.2 volts throughout the hundreds or even thousands of charge cycles until it will no longer hold a charge.

Should I recycle my old batteries?

Please recycle your rechargeable batteries—and your regular batteries, too! In some states, like California, if you throw them away, they’re actually considered to be hazardous waste. Batteries are accepted at select recycling centers (including nonprofits) and drop-off locations, including some organic groceries, Best Buy locations, and participating battery retailers, among others.

The best rechargeable batteries:

While regular batteries drain over time until they’re bricks, rechargeable batteries are much more energy-efficient and hold a consistent charge throughout the battery lifespan. Using rechargeable batteries keeps more in your wallet and less in landfills, so making the switch can make a difference in your household and beyond. Not sure where to start? We’ve got you.

They are made to retain up to 90-percent power after one year’s time and come with micro-USB ports built right into the batteries, so you don’t need to pop them into an external charger (nor do you always have to worry where said charger may actually be hiding in your house).

    The longest-lasting battery can basically transcend eras. Our picks for best rechargeable batteries include the Panasonic eneloop AAA Batteries, which can retain up to 70-percent charge even after being stored for a decade.

    Q: How many times can rechargeable batteries be recharged?

    The life of a rechargeable battery varies from manufacturer to manufacturer but, in general, you won’t have to think about replacing them for a long, long time. Some products can be charged hundreds of times, while others can go through more than 1,000 cycles before they’re done.

    Q: Do rechargeable batteries go bad if not used?

    Yes, rechargeable batteries go bad if not used. While it’s not a bad idea to keep rechargeable batteries around, it is a bad idea not to use them once in a while. Chemicals within the batteries react together when unused and start reducing stored charge. Even if many rechargeable batteries can hold charge for long periods, they will self-discharge if you don’t take advantage of it.
