Selected User Reviews For Energizer 9V Lithium Batteries, Ultimate Lithium 9 Volt Batteries (1 Battery Count)

Due to the 10 year rating of the Ultimate, I feel safer using it, but I do test the smoke detectors once a month when my wife takes our dogs to the groomers
3/5

The alarms go off, and they shake as a result.

3/5

I'm not sure how long it will last but hard to get into tight fitting holders, won't fit some items.

There is no battery life on this device
3/5

The battery was low on voltage right out of the box. It's important to know that these are still fully charged because they do not have dates. When it comes to product quality, Amazon may not be the best.

Is not expected to last very long
3/5

The smoke detectors are hardwired, and I bought 7 of them for my whole house. This means that the smoke detectors are powered by the electrical system of the house and not by batteries. Because they cost so much and are claimed to last so long, I expected them to last for many years. It is unfortunate that all of them failed after exactly 3 years.

Batteries last the same amount of time as regular batteries
3/5

As a result, I was surprised when my CO2 detector's 9-volt lithium battery died. I love it! The batteries I bought last time have run out, so I will buy another. The Energizer one cost a little less than six bucks, so I assumed they were all That doesn't seem to be the case. The battery from the other maker lasted for a longer period, but this one barely lasted a year. To January 2018, there was no school. The battery this was replaced with could have given the same amount of life and I could have gotten two for the price of It could be that the Energizer was already low on power when I installed it, or it may have been an old one. In my previous post, I mentioned the other brand that can also be.

The product works, but its durability is questionable
4/5

It was for a single reason that I bought it We make the claim that an alarm clock can provide 10 years of backup power (using this technique). As soon as I received my battery however, I noticed the manufacture date was 8- There is a use by date of 12 months and the age is 18 It would appear that older shares below the 10-year mark are in danger of devaluing Marks for each year of the year are on sale. As long as it lasts 8 years, I'll be happy with the purchase, although I'd like it if the page reflected old stock being offered for sale.

This document has not been date-coded
3/5

These are the batteries I bought for smoke detectors mounted in high places. I bought them so I wouldn't have to change them as frequently as alkaline batteries. As these batteries are not date-coded, there is no way to know whether they are new or have been sitting on a shelf for a very long time. I went ahead and installed them, but won't know for a few years whether they are new or not.
