Tianqiu AG8 391A SR1120 LR1120 LR55 SR55 L112 Button Cell Batteries [20-Pack]

The product was bought to fill a tray of small batteries, so I have no idea if they will last. I am optimistic, since my prior purchases have been reliable and long-lasting.

Probably won't last as long as name brand batteries but work just as well and for much less you get 20 not 2. I would definitely buy these again.

I received the order on April 10th and I had to replace one of the batteries I had put in my watch today, May 20th. The batteries are supposed to, and have in the past, last 1 year. So I've now put the second battery in the watch. I will post an update when I see how this second battery performs.

As I said, they did not directly replace my existing AG8 batteries. They are thinner, therefore in a stack of three they do not compress the spring well enough to make contact. Diameter and voltage are correct, but may have to make a conducting spacer in order for the laser gunsight to operate properly.

Good bargain
