Batteries for NX-458 Wireless sensors

[hawhoo]

I am running about 15-20 GE-NX-458Wireless sensors with my ELK m1 System and it has been working very well.
Now (after about 3-4 years the batteries are failing.
Is there a source for buying replacement batteries?
I do not see why I could not solder new batteries in place.

I also noticed the the advertisement for the NX-458 claims a battery live of 15 years.
I believe it did not claim that when I bought mine.
Is That a newer model? If (So I would not mind getting new NX-458s)

Thanks

Ps This is a re-post I used the wrong number 454 before..

I suspect shelf life has a lot to do with it. A lot of mine are failing too, I have decided to start slowly replacing with wired sensors.
