A long life battery to make changing the battery in my not easily accessible smoke/fire detector as infrequent as possible. Very satisfied with the "Ultralife 9v lithium battery" which lasted approximately 4 1/2 years. Excellent!

One Ultralife 9v has powered my portable headphone amp for almost 40 hours and it's still going strong! This is normally a 10-hour stint with a regular 9v alkaline battery. Not cheap, but I can imagine 5x normal alkaline life with these lithium powerhouses in low-drain electronics.

1.0 out of 5 stars 50% failure rate for sealed batteries, August 15, 2011

This review is from: Ultralife 9v Long Life Lithium Battery (Electronics)

I've been using these batteries for over a decade. I usually buy 10 at a time. The last batch I purchased had a 50% failure rate. Opening the sealed package had batteries with leaks, discolored bodies and low voltage.

Several attempts at contacting the manufacturer, including filling out the RMA form have been 100% ignored. They even have section on the website dedicated for RMAs for the batteries, so it's clear that they know about the problems.

Won't ever touch anything with the Ultralife name on it.

There are now other choices such as Energizer for lithium 9V cells. At least they actually honor their warranty.
