Customer Review: Lasts 3 years
Bought a few of these in 2004, two have started giving out, three years later.
Customer Review: Five-Year Worked Great, I’ll Trust the Ten-Year
I haven’t yet used the Ultralife 10-year battery but I can vouch for the 5-year version. I just pulled one from a smoke alarm and I had dated it July 13, 2003. So it lasted four years and four months, less than five years but it was also the smoke alarm closest to the kitchen, and thus was probably a bit drained by the fifty or so burnt cooking false alarms over the past four+ years.
Ultralife makes a truly great product so I gladly upgraded and ordered four of the 10-year batteries. The added safety and convenience makes them worth every cent.
I’ll update this review in 8-10 years when these batteries stop working. buy from here…
