Panasonic Eneloop AAA and AA rechargeable batteries features: 16-pack AAA batteries | 12-pack AA batteries | Recharge up to 2,100 times | Maintain up to 70% of their charge after 10 years (when not in use) | Up to 800mAh type, 750mAh min, AAA Ni-MH batteries
The Panasonic Eneloop AAA and AA rechargeable batteries redefine the idea of disposable batteries. Quality products and engineering mean that these batteries are good for 2,100 recharge cycles (so if you charged and discharged them daily, they’d easily last for six years).
Another plus side is that after you’ve charged them, these batteries will hold 70% of their charge for 10 years when stored, which is fantastic shelf life and means that you’ll always have charged batteries ready to go.
While I can’t test the 10 year claim, I’ve had some of these batteries on the side for over a year and they’re still close to being fully charged, which is excellent.
Amazon reviews for these batteries are also strong, with users happy with the capacity and longevity of their batteries.
