Panasonic Eneloop Pro AA High-Capacity 2550mAh Ni-MH Rechargeable Batteries (4-Pack) & AAA 800mAh Ni-MH Batteries (8-Pack) - 2100 Cycles for Digital Cameras, Game Controllers & Smart Home Devices

I've used the same AA and AAA Eneloop Pro batteries for almost 5 years. They are higher capacity and longer lasting than alkaline batteries I've used in their place. I have used them in remotes, wireless keyboards & mice, Xbox controllers, flashlights, and metal detectors. I paid a little more for these because they are made in Japan. They recharge as quick as you want but I typically charge at 300ma/h for AAA and 500ma/h for AA to maintain a balance between charge rate and charge cycles. So far, they are not showing any noticeable reduction in capacity or resistance. They are a little heavier and slightly larger diameter than alkalines but they still fit in anything I have.If you want to save money, stop buying disposable alkaline batteries and get these. I spent a fare amount of money on these batteries and a good charger but they have paid for themselves twice over in less than 5 years and they are still going.
