Panasonic - eneloop Charger and 4 AA Batteries Kit - White

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 was going through AA batteries like crazy for my xbox one and wii controllers, so I purchased a 4 pack of these and all I can say is wow! I'm not having controllers die mid game nearly as often and it really feels like these last forever.

While they are not inexpensive to buy at first, they will save you money over time as you are not throwing away batteries over and over.Panasonic Eneloop are the best rechargeable batteries I have ever had, they hold a charge even when just sitting, I use these in everything and will be buying more.

This is a great charger/battery pack for use in toys, remotes, or video game controllers (Xbox/Wii). This pack contains 4x AA batteries, but the charger can also accept AAA. It has one of the best Low Self Discharge rechargeable batteries. The batteries are Made in Japan, so they're of the best quality. The charger is of the smart variety and it uses a trickle/pulse method. It charges and senses each individual battery's level, so no need to charge in pairs. You can charge as few or as many as you want at a time, and mix&match sizes, too. There's a small green light under each battery that shows when it's charging, and automatically turns off when it's done. The downside is it's a bit slow as it takes about 7 hours to fully charge a completely depleted battery. Although, slow charging is good to extend the life of a battery.

These Eneloop rechargeable batteries are awesome. I bought this kit to use in my XBOX ONE Elite Controller. I have been using for a few weeks and still on my initial charge. I would highly recommend them!

Does just as the description says! Very good product!

Good (not great) smart charger. It has separate charging circuits so you can mix AA and AAA and charge 1, 2, 3, or 4 batteries at a time. 7 hours to charge a battery is OK since fast charging is a great way to kill batteries. There are four hidden green LEDs which indicate the state of charge. 2 issues: - Instructions say when first plugged in LED will flash and then go steady as it charges. WRONG! LED glows solid initially. If a battery is "defective" it flashes. LED does go out when battery is fully charged. - LEDs are not under the battery to which they refer so its not easy to determine which battery is fully charged and which one is still being charged. It refused to charge batteries which the La Crosse BC-1000 could charge, but it costs about 1/2 as much.

These rechargeable batteries are the absolute best they hold a charge for an extremely long time and work flawlessly
