LOOPACELL AG4 LR626 377 SR66 1.5V Alkaline Button Cell Watch Batteries 10 Pack

Batteries worked great.

They work great

The batteries are as advertised and work as expected. Got them in two days and the price was excellent.

I ordered 2 pkg of button cell watch batteries. I’ve opened one and 3 out if the 10 had green corrosion on the back… so I had to toss them

I got the batteries today, and installed one of them in a watch,which now works fine. Since I just got them I can't rate them for "Longevity" but they do work fine out of the package.

I didn’t need this many batteries for my watch but that’s the way they come. They fit well and seem to have good life. Now I have enough batteries to last a life time!

Worked for every watch I have

Upon arrival several of the batteries arrived already with corrosion noted. I needed 3 batteries for a laser. The first 2 appeared fine but the third was heavily corroded underneath which can not be seen without opening the package. Some of it wiped off but did not want to risk it damaging other batteries. I trashed the third battery and opended a 4th one. This is a 10 pack so no huge worries. The 4th battery also showed minor corrosing underneath. I wiped it away as well and laser functions fine. I will admit that I am concerned about the other six batteries however.
