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.

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.

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.

I was looking for rechargeable battery packs for my XBox One controllers and Eneloop rechargeable batteries kept coming up as a the best option. I have to say they were right. These batteries were very reasonably priced and each charge has lasted longer than I would've expected. The first charge lasted 8 days of moderate daily use, using it to navigate netflix, youtube and hulu during the day and about 3 hours of Forza/Call of Duty at night. Great batteries! I also love that the charger charges each one individually and turns off each one when its ready. I'm on the second recharge and I'd say they've paid for themselves already.

A thing I always worry about rechargeable batteries are that they tend to die more often than the non-rechargeable variant. However, I've had no problems with these I've actually bought these twice. I use them for my PowerA controllers which use batteries rather than charge. I tend to switch batteries on the charger about once a week. So far, haven't noticed any lower charge rate or any dead batteries.

I read reviews all over the internet before I bought my 1st set of these. From user reviews on here and amazon, to CNET and Consumers Reports. These batteries have a great combination of charge cycles and long lasting. I use 4 of them to swap out in my xbox one controller. Two always on charge ready to go, and they last longer then any other rechargable batteries I have tried in any controller over the years. I bought another set for my nephews Xbox and a third set for my girlfriend. They are both very happy with them as well.

When the rechargeable batteries from my two-way radios stopped holding a charge I came across this brand through a lot of great reviews. I am more satisfied with these compared to other brands like Energizer and Duracell. They hold a charge for a good while both when in use and in storage. I even bought an extra pack of 8 for a couple of wireless mice and TV remote and keep the spares in a drawer. The charge indicator is really helpful since it lets you know when to pull out the batteries once fully charged.

Everybody should have rechargeable batteries in the home. How many remote controls do you have in the house? My three Roku Ultras eat batteries and I'd be buying tons of AA batteries and tossing them in the trash when depleted if I didn't use rechargeable batteries and Panasonic Eneloop batteries are the best.
