The gold standard for rechargeable batteries. If it were up to me, we as a society would have never switched over from AA/AAA batteries over to li-po or li-ion batteries.

First time using these, was looking for rechargeable batteries for Xbox controller. Very easy to use and you will get two extra batteries charged up and ready to use.

I got these batteries some time ago, but they are pretty good. Surprisingly haven't even needed to recharge them yet.

I bought this product to have rechargeable AA batteries for my xbox one controllers. I was flying through normal alkaline AA batteries and everyone knows that even alkaline batteries aren't that cheap. Buying and owning rechargeable batteries is an investment that will pay itself off ever time. The only inconvenience is remembering to charge the batteries. Comparing this version of the Eneloops to the Eneloops Pro, the main difference is how much charge it holds and how many times it can be recharged before seeing loss in performance; 2000mAh w/ 2100 recharges and 2550mAh w/ 500 recharges respectively. Doing the math: Reg. Eneloops..... 2000mAh x 2100 recharge = 4.2 million mAh effectively. Pro Eneloops..... 2550mAh x 500 recharge = 1.275 million mAh effectively. The xbox one controller draws 480 mA to operate meaning: Reg. Eneloop..... 4.2 million mAh / 480mA = 8,750 hours of use. Pro Eneloops.... 1.275 million mAh / 480mA = 2656.25 hours of use. The regular Eneloops has a lifetime operation approximately 3.3 times longer than the pro version. Normal AA alkaline batteries can range anywhere up to around 2600 mAh(sometimes even more) but the mAh is dependent on how much current(mA) is being drawn. Looking at a datasheet for energizer alkaline battery(E91), the effective mAh at a current draw of 480mA is a disappointing 1500 mAh. Honestly, don't waist your money on the pro version unless you absolutely need those extra 550mAh; the only sacrifice for a gamer would be another hour of use per charge. All in all though, great batteries and an excellent charger. Your future self will thank your past self for investing in these batteries.

I have so many eneloop batteries and the quality has been consistently great. They are not cheap but the investment is well worth it. Even after many years, these battery still hold a very good charge.
