Panasonic Eneloop AAA and AA batteries redefine the concept of disposable batteries. High-quality products and engineering mean these batteries last as long as 2,100 charge cycles (so for those who charge and discharge them day-after-day, they’ll easily last six years).
Another advantage is that when charged, these batteries retain 70% charge for 10 years of storage, which provides improbable durability and means you will all the time have charged batteries able to use.
While I am unable to test the 10-year lifespan, I’ve had some of these batteries on my side for over a 12 months they usually’re still near being fully charged, which is superb.
Amazon reviews for these batteries are also good, with users satisfied with the capability and sturdiness of their batteries.
