verdict: Worth a look

The GP ReCyko 2100mAh rechargeable AA batteries are recommended for 500 cycles – but do they hold on to their capacity, and do they have the stamina to keep your devices running for a decent length of time? We tested them to find out. Read the full review for our verdict.

Pros
  • Hold their capacity over the long-term
  • Relatively quick to charge (271 minutes)
  • Good life per cycle for a rechargeable battery
Cons
  • Lose their charge quite quickly when unused
Although these aren’t Best Buy batteries – partly because they’re quick to lose their charge when left unused – they’re both long-lasting per charge and maintain capacity over hundreds of cycles. Because of this, we recommend them, especially for devices you use frequently. But it’s worth checking out our higher-scoring rechargeable batteries too.

 verdict: Long lifespan

GP recommends its ReCyko Pro 2000mAh AA rechargeable batteries for up to 1,500 charges. We tested these batteries in our lab to find out if they’re better than rival rechargeables from brands such as Duracell and Panasonic. Read our review to see our findings.

Pros
  • Maintain capacity over the long-term
  • Charge in just 257 minutes
Cons
  • Disappointing duration on a single charge
  • Don’t hold on to charge well if unused for a few weeks
These rechargeable batteries don’t last particularly long on a single charge; they’ll run a high-drain device for just under three and a half hours. But they do last, maintaining their capacity very well over 200 cycles. We’ve found superior rechargeable batteries, but if you’re keen on using the same set for half a decade, these are worth a look as their endurance is very good.

 verdict: Good for long term use

Energizer says its Recharge Power Plus AAAs are a ‘world’s first’ because their make-up includes 4% recycled batteries. These 700mAh batteries claim to give 2.5 hours of device activity on one charge, and that they can be charged 100s of times. However, on paper these are some of the lowest-capacity batteries we’ve tested. Find out in our full tests if these batteries can maintain their battery life over hundreds of uses and how long they’ll last in your high-drain devices.

Pros
  • Will power your gadgets hundreds of times before power drops
  • Retain charge well if they’re not used
Cons
  • Battery life on a single charge is only acceptable at just over three hours
  • Charging time is rated poor taking around 3hrs 25min

 verdict: Top of the table, the best AA rechargeables we’ve tested

Panasonic describes the Eneloop Pro batteries as the best of both worlds, combining the performance of a disposable battery with the cost-efficiency of a rechargeable. So we put them to the test to uncover how well they maintain their charge after multiple uses, and how long they’ll last on a single charge. See our finding in the full test results.

Pros
  • Exceptional battery life with long-term use
  • Good at retaining a charge when not in use
  • Excellent lifespan from a single charge
Cons
  • One of the most expensive batteries on test
  • Don’t retain their charge for as long as other Best Buys
Panasonic’s Eneloop Pro AA batteries live up to our expectations as a reliable energy source for your devices. Our testing found that they do a superb job of recharging to 80% capacity, even after hundreds of uses. Life from a single charge is also stellar, providing plenty of power for your high-drain devices, such as a digital camera. A fantastic Best Buy battery.

 verdict: A-star AAAs.

You can recharge the Philips Ready To Use 1000mAh batteries 1,000 times, according to the Philips, negating the need to buy disposables for a long time. But are these rechargeables the frugal option you should go with? Read our review to see our verdict.

Pros
  • Last a long time on a single charge
  • Maintain capacity over hundreds of charges
  • Hold on to charge when not used for a while
Cons
  • Nothing significant
These batteries are the best AAA rechargeables on test as of 2021, and it’s no surprise: they last for nearly four hours on a single charge, and maintain their capacity over many more cycles than standard rechargeable AAAs. They were reformulated recently, so if you bought some before and weren’t impressed, they’re well worth another try.

 verdict: A good long-term investment

GP’s ReCyko Pro 800mAh batteries promise 1,500 cycles over their lifetime. We tested them to find out whether they’re the best ones to invest in. Read our review for our verdict.

Pros
  • Maintains capacity well over hundreds of cycles
  • Decent duration in high-drain devices
Cons
  • Trades charge time for longevity
These Best Buy AAA batteries last three and a half hours in high-drain devices like baby monitors, and their capacity dwindles slowly, which makes them a good long-term investment. They’re ideal if you’re an highly frequent battery user, saving you lots of money and hassle. We wouldn’t hesitate to recommend them.

 verdict: Best Buy AAA rechargeables

These Panasonic batteries have previously done well in our tests. Panasonic says they’re ready to use straight from the packet, since they’re pre-charged. But for how long do they power your devices? And do they power them consistently well over multiple uses? Our full lab test results reveal all.

Pros
  • Among the best AAAs on test for withstanding long-term use
  • The best at staying charged when not in use
  • Great value
Cons
  • Other batteries last longer on a single charge
If you’re looking for great-value, reliable AAA rechargeable batteries, then look no further. Even after hundreds of recharges, these Panasonic batteries still maintain their capacity, so you won’t be left in the dark. Although other batteries last longer between charges, these won’t lose charge when you’re not using them.

 verdict: Powerful

Ansmann claim its AA Max high-capacity 2500mAH batteries can be recharged up to 1,000 times, promising to power your high-power devices time and again. They’re also claimed to recharge super quickly. We’ve tested them to find out whether they truly have a very low self-discharge, and whether they’re the right battery for continued use. Read our full results below to see what we found.

Pros
  • Good for long-term use
  • Really impressive battery life on a single charge
Cons
  • Drop to 60% capacity after fewer cycles than others
  • Not brilliant at retaining charge when not in use
The Ansmann AA Max 2500mAh will give you plenty of power on a single charge, and in this area they’re really impressive, earning them a Best Buy recommendation. They also last for a great number of cycles before they drop down to 80% capacity, although they do drop to 60% in fewer cycles than other Best Buy batteries we’ve tested. That said, they’re still good for long-term use. It’s also worth noting they’re only average at retaining charge when you’re not using them.
