This battery is a replacement for Eveready ECR2012; Other SB-T15
These are replacement watch batteries and replacement small electronics batteries.
In use working fine.
The battery was specified for my wristwatch and fits perfectly.
They were great. Let me return a battery when I'd ordered the wrong one.
I could not find the battery locally (Phoenix area) and I received it at a fair price, several days after I ordered.
My watch is working great again.
These were batteries for my watch. They arrived in a timely manner and performed so far as expected. I had bought one from a big box store and it ran down in a matter of weeks. It should last around 9-12 months.I think that the fresher the battery the better it's service life Only time will tell.
