ENVIE® (AA2100RTU4PL) Infinite High-Capacity 2100 mAh AA Ni-MH Rechargeable Batteries with Low Self Discharge (Pack of 4)

A bunch of people who can't read specifications and don't really understand technology are buying this product without understanding the use case and writing negative reviews. They complaint the voltage is only upto 1.3 V even after charging for 24 hrs. This product is rated to provide 1.2 V only and that is so because it is supposed to work in cameras where 1.2 V is the requirement. And voltage has got nothing to do with charging time. Probably these guys never went to school. The product quality is top notch and the price is unbelievable. I checked the price of batteries from Sony for the same specs and they cost 4x. Now probably their quality will be a tad better but definitely not worth the price. I have used Sony batteries prior to this and I don't find any quality/performance issues with these new batteries.

I have ordered this rechargeable battery for my son's toy. I used this product on the charge it came with for 1 month for several times while I removed it for recharge I found that batteries were leaked. I contacted for warranty and it was smooth after providing the invoice and battery leakage pics in whatsapp. The replacement product is shipped in one day and yet to receive it. Overall I am not sure why the battery went out before first recharge, I should try out the replacement product to write review on the battery quality and life. Thanks.

If you are a photographer and want to use these batteries for your flash go for it. The value they provide for the price is just amazing. It's a cheaper alternative to Enloop batteries, but the performance is almost as good as Enloop. Definitely recommended product.

Initially sent product looked low quality/duplicate/used. Even the stickers on couple of batteries was partial. Contacts looked as if used ..dull & brownish. Got it replaced. Replacement looks like original will update after using for few eeeks

A full charge to the batteries' capacity of 2100 MaH makes it rather long in my cordless mics, I think as much as Duracell Alkaline batteries!

👍

These are very poor quality batteries in terms of build quality, performance and charge retention capacity. Doesn’t feel solid and heavy compared to other rechargeable batteries I used including Panasonic and Everedy. I noticed the battery casing bent inside at the negative terminal after it was inserted into the battery slot of appliances. It takes a lot of time to charge, never finishes charging and overheats the battery and charger. Instead of buying these cheap Chinese products, better pay up a little more and buy quality products from reputed brands.

This is my second order of buttery works well for kids toys
