The flipside is that the maximum number of times you can recharge the batteries over its lifetime is rated at 500, compared with 2100 times for regular Eneloop batteries. They’re therefore ideally suited to power-hungry devices with a hefty current drain.
Compared with regular ENELOOP batteries, they have a higher capacity of 2500mAh compared with 1900mAh, outstripping alkaline batteries as well as many rechargeable options. Indeed, the batteries are rated to work in temperatures from -20 to +50° C (-4° to 122° F).Īs with most recent NiMH batteries, they come pre-charged (using solar power, no less) and are ready to use, straight out of the box.
#Duracell rechargeable batteries lifespan pro#
At Digital Camera World, we’ve been using Eneloop Pro batteries for years and have enjoyed 100 per cent reliability, even in the harshest conditions. That can be really frustrating if you go to use them, only to find they’ve gone flat.įor photographers using batteries in their flashguns and anyone who needs to be able to trust their kit in critical situations, reliability is a key factor. Even so, early versions and many that are still available today tend to discharge over a few weeks after being fully charged, even if they’re just sat in a box doing nothing. They don’t suffer from a memory effect and enable higher electrical capacities, so last for longer between charges. Since the 1990s, NiMH (Nickel-Metal Hydride) batteries have been a much more popular choice for popular battery sizes like AA.
Cadmium is also toxic, and its use was banned in many world regions in the early 2000s. Nicad (Nickel Cadmium) batteries were invented all the way back in 1899 and were still popular in the 1990s but they suffered from the dreaded ‘memory effect’, so you’d typically need to discharge them completely before recharging them. But they haven’t been without their problems. Rechargeable batteries have been available for years, as a viable alternative to alkaline cells that typify the ‘throwaway culture’.
