Panasonic BK-3HCCE/4BN Eneloop (Up to 2550 mAH) Pro AA high Capacity Ni-MH Pre-Charged Rechargeable Batteries, 4-Battery Pack (packing may vary)

These are some of those stuffs that you buy only once and use it like forever until you've lost it. I've had bought these batteries for my xbox S controllers. IT WORKS WONDERSS!!! I'm an occassional player who only plays on weekends and these batteries have performed so great that it lated for two months on single charge. Once I played constantly it still lasted a week. I'm imply amazed by the longetivity, quality, charging speed and overall functionality of thee batteries. I'd say these are the bet AA rechargeable batteries on earth tthat you could buy. A litle expensive for sure but frr, it's 100% WORTH IT! NOTE:- Please use official panasonic eneloope charger only to charge these for the best performace and longetivity.

This review will answer some of the questions you might be having or at least I had while ordering the Eneloop Pro AA batteries.I ordered on Mid July, 2020 from the seller Appario Retail and got "Made in Japan" batteries from June-2019 (Hence the 1 star reduced in the review). So, if anyone wants a recent stock, I would suggest purchasing offline from a Panasonic Store or trusted electronics store. This is not a major issue for me since I am more concerned about getting original Eneloop Pros vs fake ones. They will last years anyway.Also, side note, if you're worried about choosing Eneloop regular or Eneloop Pro, I would suggest going with the Pro as it has two big benefits, higher capacity and more power. These really do matter. I would not worry about 2100 cycles in regular Eneloops vs 500 cycles in Eneloop Pros because basic maths will tell you even if you charge 2 batteries weekly twice every week the Pros will last about 5 years. I got a pack of 4 for the same device so I am good for about 10 years, provided they are genuine. Honestly, I don't believe even my device will last that long. Also, Eneloop Pros have less fakes in the market than regular Eneloops.I had purchased an Xbox One controller and needed rechargeable AA batteries for that and Eneloops had overwhelmingly positive reviews on reddit and pretty good reviews on YouTube. Suffice to say, it's the people's choice due to longevity and quality. And hence, I ordered these batteries.Now coming to the genuineness of the batteries, the major concern I had while ordering Eneloops was whether they would be genuine since there a lot of fakes in the market and if I am investing Rs. 1060/- I should get a genuine product. I can only do tests that are not very technical in nature and more of what a common person can do.Fortunately the batteries so far seem genuine to me. I had looked at some indications to tell if the Eneloops are fake, a quick search on YouTube and Google should make things clear if you want to find them out. Although those videos and articles are a bit outdated, you will get an idea of what to check. I have attached a pic of the backside, that's the one I got.The packaging was fine, it arrived bubble wrapped. The batteries had no sign of damage. The individual batteries weigh precisely 30 grams as they should. The package has no spelling mistakes, line spacing mistakes, color change. So all good from first glance. The real test is the charge retention. The batteries that came with Xbox one controller lasted 5-6 days on medium to heavy gaming with vibration. Those batteries were of the same capacity as Eneloop Pros. Eneloop Pro batteries hold upto 85% charge in a year, and since these batteries are manufactured a year back, I should be able to play for at least 4 days. Less than 3 days would not be acceptable at all.Another test I would be doing is that I'm using only two batteries on the controller. Two are left in the pack itself. I'm getting the Eneloop Advanced charger in a couple of days. I will charge those two batteries which are left in the pack and I will discharge the ones I put in the controller completely and charge them, I will note the time difference.I will update the review once I have done that.Edit: Two of the batteries were fine, but the other two were defective. They didn't hold charge. I have ordered replacement.

They are good battery but any toys which needs rxact 1.5 v will not support these like nerf gel blaster whoch have 8 battery did not operate with that . But its not a battery problem they working fine in other toys.

Very nice

Durable batteries, Fast Charging. Value for money.

Good product

Rs-1641 (it was on discount) (For 3*4=12) (AAA 800 mah)Capacity doesn't mattered for me so I bought normal one instead of pro as pro have less no of rechargeable lifeBought -10 May 2025Received-13May 2025Review -18 May 2025These are the best rechargeable on the market so no problem with them(will update if any battery have some problem , Heard they have lasted 10 years for some people so I am excited,I hope I never have to update this review )Product packaging of one was damage but no damage to the battery

Not recommended for heavy duty use. Cells have life of only 3 recharges. Don't waste money. Charging speed is okay but battery drains very fast. Not functioning as claim. Appearance is not matching it's working
