Date code?

I bought a 5 pack of 2430 batteries, there is no date on the battery or the package. There is JC printed on the back of each tear off which I'm assuming is a date code (my previous package had WI). What would the manufacturing date be and how long do these batteries last if unused? Why are the dates coded, we consumers look for these details when buying batteries?
thanks

Answer: 

It sounds like you purchased a pack of batteries packaged for our professional customers. Most of our professional packaging does not contain any reference to code date, with exception to the ink print on the back of the cell itself. For the item you're referring to, it has an expiration date of Oct 2018. With that said, on any of our current packaging at retail outlets you should be able to find the code date on the front of the package, typically in the bottom left-hand corner.

Hope this helps.

Answer: 

Unfortunately, we do not provide this information in our datasheets for any of our Coin Lithium types, but for the 2430 and 2450 batteries, they will perform in extreme temperatures from -22ºF ~ 140ºF or -30ºC ~ +60ºC.

How long before the voltage goes below 2.8 with a continuous 12uA draw?

We have an OEM application where the CR2430 is responsible for maintaining a real-time clock which pulls 12uA.

How is this impacted at the temperature extremes. The battery will be exposed to ambient temperatures at 130F.

Thanks!
