Great Product
I received my Energizer Ultimate Lithium 9V Battery just as my smoke detector started beeping needing a new battery, perfect timing. Or so I thought, though my smoke detector takes a 9V battery, the new Energizer battery did not fit my smoke detector, I was not aware that 9V batteries came in different sizes. I have purchased other Energizer batteries and they work great, so I know when I eventually find something that this battery fits in it will work just as great. Once I start unpacking my Christmas decorations, I have a couple of items that require 9V batteries. Can’t wait to put it to good use. Though I was not able to use the Energizer Ultimate Lithium 9V Battery for what I intended, I do highly recommend them, Energizer batteries are great batteries.

Top‑tier in terms of performance
Excellent longevity: they last far longer than standard alkaline batteries. Wide operating temperature range: (‑40 °F to 140 °F or about ‑40 °C to +60 °C), making them suitable for cold weather/outdoor use. Lightweight: As lithium primaries, they are lighter than comparable alkaline cells (useful if weight matters). But these batteries cost significantly more than standard alkaline batteries.

Works as expected
No surprises with this battery. Needed this size for one of my kid’s toys and I expect the battery will outlast the toy. I appreciate I could get just one and didn’t have to buy a giant pack since this isn’t a typical size.

The only battery I use
Energizer ultimate lithium batteries are all we use in our home. They last and they are so incredibly dependable. I use the 9volt batteries in our smoke detectors and I know that they are going to last and not die on us as soon as we put them in.

Great battery
I got this battery, and am using it in my smoke detector. I'm expecting the battery to last a while. As always, every six month a check will be conducted. It does have sharp squared shape to it unlike the others that are rounded of. It still worked and fits great.

Energizer Ultimate Lithium 9V battery
I was very excited to receive my 9V battery. It was packaged very similar to any other 9V you would get. My purpose for this battery is to put it in the control unit of my water softener. It is important that this battery stay strong for a very long time to hold the data for the water system. I have currently had it in my system for almost 2 weeks and it is going strong. I have always been an energizer supporter and this one continues to prove my loyalty. Go get you this battery and put it in your electronic that you rely on.

Great 9 volt battery
I needed a 9 volt battery for my smoke alarm and I chose Energizer. Such a trusted brand and I like that it is a lithium battery and will last for years. I also like that it has a 10 year shelf life so I can purchase a backup battery for when my smoke alarm needs a new one. The safety of my family is my priority and having an Energizer battery is the only brand that I will buy.

I sleep safer at night with Energizer!
After working all day, I like to come home, bath, eat a little dinner, and then spend some time talking and relaxing with my family before bedtime. I love my family so much and the house we live in must keep them safe and healthy! It's a single story nestled in a large grouping of pine trees with a little stream bubbling in the back yard with inlaid security and fire, smoke & motion detectors everywhere! Thanks to the dependable, long-lasting Energizer Ultimate Lithium 9V batteries that power most of these safety devices, I sleep really well at night knowing that my family is effectively protected from harm!!
