Customer Ratings & Reviews

4 NiCad batteries are around $15 without a charger. These cost me $10 on clearance so I bought two packs. They are lithium and charge from any USB port. Great deal and they work great too.

I used these to replace Duracell alkaline batteries my son was using for his Xbox controller. Duracell is probably the best alkaline battery available, at least longer lasting than any other I've tried (EveryReady, RayOVac, Radio Shack, Panasonic, Phillips, Kirkland). He was going through the Duracells like water. These cost about the same as the Duracell 40 pack at Costco. They recharge fairly quickly and last about as long as the individual Duracell AA's. They've lasted past a 40 pack, but I've only spent the $20 once. So, I'm in gravy mode at this point. So far so good, and worth the purchase. I plan to buy more for me and my daughter.

This is by far the best invention ever. Rechargeable without having to buy adapter

I love that i can just recharge these batteries via USB, makes them very convenient.

I bought these for my Apple mouse. The charge is done thru a USB port and it's complete in 2hrs

We bought these AA rechargeable Eco Cell batteries for our new camera we like how we can charge them in a USB port anywhere they are AWESOME

I placed my online order two days ago and it said it would be delivered within a week; but it arrived two days later, that’s just crazy perfect service, unbelievable.. I love it, keep it up BestBuy. And thank you so much.

I bought these to use in a mouse and keyboard combo that I use for work every day. The last about two weeks before they need to be recharged. I have since switched to putting them in remote controls for TV/cable box and they last much longer there, since they aren't in constant use.

Great price for batteries that will help my daughter keep taking pictures!

I bought some cheap knock off versions of USB rechargeable batteries online and found something I never thought to find in a battery - Electrical Noise! I couldn't believe it. After putting one of the cheap USB batteries in my headphones there was a very distinct and noticeable background hiss. I then took it out and put one of these in and the hiss was gone. Now, this issue might not apply to all situations where you use batteries but it is something to consider. These batteries don't have that problem.

I absolutely love these. The concept is fantastic. I use them regularly. I need to invest in more because I use them for my wireless computer mouse and wireless keyboard but wish I had some extra to swap out when my batteries go dead. They are so easy to use and to think I can just charge them up from my computer USB ports is pretty great. I usually just keep some regular batteries on hand in case I need to charge these up then I swap them back out once these are charged. I highly recommend these.

Charge in <2h, perform very well. Extremely Happy.

These batteries are great. The batteries died in my new Nikon B500 camera that I bought from Best Buy after about 3000 pictures, I was in the middle of shooting when the camera shut off. I had these batteries as back ups and charging in my car on the USB car charger. Popped them in and back to shooting in no time. These are great because I can charge them as I am driving to my shooting locations. I will always have charged batteries!

Best back up batteries. Best used for charging up your phones and other USB connections and other things that many my phone another quick connection that I can use USB connection

This is an unusual product as it uses Lithium Ion batteries packaged to perform as AA battery replacement. They are quite expensive to purchase. Currently using them to power Apple mouse and keyboard. Time between charges is longer than previously used conventional rechargeable batteries. They recharge via a USB port charger, and take about 45 minutes to reach full charge. So far am pleased, how long they last in service is the big factor.

Like the amount per pack. They are simple and very effect.

Save money using Rechargeable AA batteries. What's not to like. So far they seem to be holding out well as replacement batteries in my XBox One controller. Charge one set while using the second set. They've been through about six charging cycles so far and seem to give me comparable playing time as alkaline batteries that I was using. My only concern is the possibility of losing the cap that you have to remove to be able to recharge them. There's a magnet on the cap that allows them to be placed on the back end while charging but it doesn't take much to dislodge it and if I lose it then these batteries would be useless. Good value so far.

Save your money on buying regular batteries! Lasts longer and charges fast.

Very convenient, long lasting, fast charging no need for bulky chargers.

Ordinary rechargeable batteries won't last in my digital camera. Two or three charges and they're history. These lithium ion rechargeable ones last a long time, recharge quickly and hold their charge. After a month of non-use they're still fully charged. My NMH batteries would be dead as a mackerel long before now. They can be charged with a computer's USB cable.
