Compatible with far more devices than other brands

These batteries are great for people suffering from Xbox battery issues of having to buy tons of batteries. They also charge fast but the value I didn't really get. I guess now it's a bit more. Don't go out if you are looking for 4 batteries for this price because these are really good.

Great price for nice batteries

I bought 16 of these batteries. It's a perfect set. These batteries are so much better than the typical alkaline AA batteries for some devices. I mostly use these in a few wireless keyboards and mice. These batteries give a constant 1.5 volts. But an alkaline AA battery will slowly lose voltage until it's completely gone over its life. So far they work great.

Nice product!

I like these Cool Gadget Rechargeable Batteries. Compared with single-used batteries, this kind of battery is built to be charged repeatedly. More expensive upfront cost than single-use batteries but cheaper in the long term. (the more you use them, the cheaper they get). Highly recommended!

Really amazing!!!

I bought these batteries out of curiosity, and I didn't expect them to be so nice!!! I have a lot of devices that need batteries, but when they are out of power, I have to throw them away. I realize this kind of action harms the environment, because the traditional battery pollutes the water especially.
When I got this box, I was excited to find out the combo has 4 batteries and the cable can charge them at the same time. Excellent stuff! I like it a lot!

FAQ

What is the aa battery voltage?
For example, an alkaline battery, like an AA or AAA, has a nominal voltage of about 1.5V, while the voltage of a LiPo battery will usually be around 3.7V.
Can I use a 1.5-volt battery in place of a 1.2-volt battery?
Yes, most definitely. Using 1.2 V rechargeable batteries will have no effect on the use of the equipment. In fact, an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge.
What are 1.5 batteries used for?
1.5V batteries are one of the most common portable single-cell power sources available and are generally used in small electronic devices such as games, toys, torches, and remote controls. They come in a wide range of types and pack sizes to suit all needs.
Can you use AA charger for AAA?
Yes. Each slot is completely independent, so you can put either AA or AAA in any slot.
