EnergizerCR2032 Replacement Batteries for Cayeye, Sigma, Knog, Planet Bike & Many Others, X 15

There seems to be no transparency as to the freshness or if these are firsts or seconds. I test every battery before installing in client's products, just about 8-10% are bad right out of package, reading below usable.I got through enough batteries to determine this is not a fluke.Energizer corporation, how about putting a production date on each individual pack ?

I needed batteries and these work

I've had this order for 3 months now and find that these batteries only last half as long as store-bought batteries but on the other hand, they only cost half as much, so its a wash. Next time i will just buy from a store.

Saved some $ over local stores. Working great so far.

Just what I needed..good price. Fast delivery

Works perfect and the price is reasonable.

Need more.

So far so good. based on two weeks use it appears the batteries are of good quality
