Piece of junk lasted 1 year!!!!!
Piece of junk lasted 1 year!!!!!! It says lasts "up to 10 years!" Lasted one year in hard wired smoke detector and paid a small fortune for it!
Would not buy again!

Lasted only six months
Last fall the regular battery in our smoke detector went dead after one year. I bought an Energizer Advanced Lithium battery with the thoughts that it would last several years, especially since it was twice the cost of regular batteries. Six months later the battery charge is gone. Last only 1/2 the life of a regular battery for twice the cost. Last one I buy.

Lasted About a Year
Like many other reviewers that had issues, I am another one of them. I bought the Lithium battery for a smoke detector, in hopes of lasting the same 10 year lifespan of the smoke detector. Yet, here I am replacing the battery after a year, but at 3 times the cost of a alkaline battery.

I purchased 12 of these for a client's safety edge that required a lithium battery ... 5 days later the devices are beeping because the batteries are low again. These are totally worthless!!!

Only lasted 3 1/2 months...
These batteries are suppose to last up to 10 years...ha...they didn't even last 4 months. I think a regular 9V battery lasts longer than these. Don't spend $10 on these batteries.

Advanced Lithium Longevity
I used this battery for all my smoke detectors. Now I do not have to worry about changing it every year or battery acid leakage. Saves money in the long run.

Great for Wireless Mics
As a music teacher i know how important our wireless miss are. We used to use the Duracell Procell botteries until in one performance one went flat on us so we changed and now i am confidente in using these batteries and that they will not go flat half way through a performance.

Bought this less than a year ago
This battery does not last longer than your regular 9v battery. I don't see how they can put "up to 10 year back-up battery" on a battery that last less than a year. I used the battery for my AC powered smoke detector. I purchased two so lets cross fingers that this one last longer than a year.
