Rated 5.0 out of 5.0 by Trevor Unbelievable similarity among all of the batteries
The most amazing product I think I have ever purchases. Literally every single battery, and there were 4, was the exact size and shape. It made fitting them into my small remote control duck a breeze. I did however have on hand an impact wrench and a small hammer just in case they would not fit in the duck easily. BUT to my surprise they did. THEN like magic they produced power. I couldn't see the power but I know it was there because the little feet on the duck whirled around endlessly. Even after putting the cover back on the duck I was able to still use the duck and the batteries seemed to power it for quite some time. Almost 3 months after the purchase and the magic continues. If you think you need batteries I highly recommend these funky inventions. You will probably be just as amazed at me at the relative simple use and ease of installation. I have not tried this product in everything I own, BUT I have no doubt if it fits it will probably provide the same results.

Lithium batteries are the only battery to use for any wireless device. They cost twice as much but last five times longer.

I bought these to use with an LED flashlight, and I was very surprised at how much brighter my flashlight was over how bright they were when using alkaline batteries.

These batteries last so much longer than the standard batteries and a well worth the extra price.

Rated 3.0 out of 5.0 by BoulderSnowman Good battery for high-drain devices, very expensive
This is a great battery for high-drain devices such as cameras or LED flashlights. However, it is far too expensive for what it provides.
Recommended, only if you need it for an emergency battery for high-drain devices; otherwise rechargeables are far better.
