### ⭐⭐⭐⭐⭐ They work on my Grandfathers Pentax Spotmatic
*by B***E on September 18, 2024*

What's to dislike!!! They work and at a GOOD price !!!

### ⭐⭐⭐⭐⭐ Battery NOT dead
*by K***S on August 9, 2024*

People who keep saying it arrives dead need to look closer at their battery tester. The BOTTOM bar is for button cell battery... Shows this battery is GOOD. The TOP signal bar is for OTHER batteries (shows dead).Good customer service as well... Gave fast refund when I received the wrong battery. Then shipped the right one fast.

### ⭐⭐⭐⭐⭐ Bought to replace a battery in a 1960's Accutron
*by J***T on April 23, 2020*

My Dad has an Accutron watch that my Mom bought for him back in the 1960's. He hasn't been able to find a battery that would replace the one he put in back in the early 2000's. After some research, I found this battery and it came with the spacer ring needed to retro fit into his Accutron. A little slow on shipping, but I expected it with all that is going on right now. Works perfectly and very reasonably priced.
