That’s a lot of time for devices used infrequently or with minimal power, like TV remotes or flashlights. If you aren’t using them immediately, they can maintain a storage charge for up to a year.Įach charge gives these batteries 5.5 to 8 hours of use.

These batteries are pre-charged and ready to use right out of the package and can be recharged about 1,000 times in their lifecycle, potentially replacing hundreds of single-use batteries.Įnergizer’s “Extended Life Composition” also promises up to five years of regular use before they need to be recycled.

They’re also made from 4% recycled batteries, making them more environmentally friendly. This set of eight AA batteries from Energizer is an excellent household pack for keeping remotes, cameras, and kids’ toys up and running year-round. That’s quite a slow-down over time and alkaline batteries tend to run flat after about 115 full-power flashes.Runs down somewhat quickly between charges On alkaline batteries, we tend to get a recycling speed of about 3 seconds after a full-power flash with fresh batteries, dropping to 6.5 seconds after 50 flashes, 9 seconds after 75 flashes, and 13 seconds after 100 flashes. The precharged batteries retain their charge well for a lengthy shelf life. To test the performance of AA batteries, we put a set of four into a Nikon Speedlight SB-700. These Panasonic eneloop BK-4HCCA8BA AAA batteries deliver 1.2V of reliable power to your household electronics and can be recharged up to 2100 times for long-lasting use.

Putting a fully charged EBL 1100mAh AAA battery into a high-power mini flashlight, we got 85 minutes of use, slightly more than the 80 minutes from the equivalent Powerowl Pro Goldtop, and about twice as long as when using an alkaline AAA battery. EBL also sell 2300mAh and 2500mAh AA batteries, as well as 800mAh AAA batteries. The 2800mAh AA and 1100mAh AAA batteries that we tested are at the top of the range for capacity. A nice touch is that the batteries are supplied in robust storage cases, taking up to eight AA or AAA batteries each. The design also features protection against over-charging, over-discharging, over-voltage, over-current and short-circuit. Safety features include a steel casing to resist over-pressure and avoid the risk of leakage. Like all NiMH (rather than older Nickel Cadmium) batteries, there’s no ‘memory effect’, so you don’t need to fully discharge them before recharging. These EBL batteries should last for longer overall, with a claimed maximum of 1200 charge/discharging cycles. For example, it’s stated as 500 times for Panasonic Eneloop Pro and around 400 times for some Duracell rechargeable batteries. Some of the best NiMH batteries on the market only have a relatively limited number of times you can use and recharge them over their lifetime. We’ll come back to that later in our ‘performance’ section. Better still, although they’re only 1.2V (Volts) rather than 1.5V to start with, NiMH batteries tend to hold a much more constant output voltage than alkaline batteries over their entire discharge period. With capacities of 2800mAh (milli-Amp hours) for AA and 1100mAh for AAA, these ones easily match or exceed the capacity of most alkaline batteries of the same size. It’s a bit of a fallacy that NiMH batteries don’t last as long as non-rechargeable alkaline batteries when in use.
