How long do Energizer Ultimate Lithium 9V last?

Matt R November 15, 2021 0

Without intending to do an official product test, review or video, I put the Energizer Ultimate Lithium 9V into a few smoke detectors in my folks house during the summer of 2018.

Basically, the video speaks for itself: they lasted MUCH longer than I anticipated. A 9V in my experience lasts a little shy of a year, sometime longer, so double that was my thought, and not much more. Well, a full 40+ months longer…… well, it’s short so check out the video and leave your comments for me please!

What else should I test the lithium batteries in?

Have a great one and remember to ask your office supplier for info and volume pricing! ~TMG
