Very good value for non chinese battery and Expiration date 09/2027
Measured 1.60V on all three batteries. The Expiration date is 09/2027 and production code is :49 which i assume to be September 2024. I got these batteries to replace the dead battery in a vintage (1980's ?) Casio FX-115M.

Seiko watch battery
Apparently, some Seiko watches Prefer this battery over the 395 battery, and , this battery is slightly smaller than a 395 battery

Battery
The installation was easy, I still don’t know what to expect for the battery life because it’s to soon but last time I bought them last for 1 1/2 years so nothing impressive, for the money and the availability to have it soon I will potentially ordered them once again

Works great, nice value
Needed to replace batteries in 2 watches but singles pretty much cost as much as this 3 pack. Bought these in April 2022. Both watches are still working (as of early December 2022) so this is a pretty good value.Paid $4 with free shipping at time of purchase. Looks like its gone up by 90 cents since then but still good value.
