I used to buy the “D” brand…. I started buying these and they last about 5-6 months longer. I can tell because I use them in my battery operated toothbrush. Worth it!!

I was tired of batteries corroding, ruining what they were installed in. As far as I know, these lithium do not corrode. These are a long lasting battery. Worth the extra cost.

I have battery powered shades in my home. Nothing but lithium batteries work and last due to daily operation of the shades. I get a couple of years out of each shade without changing batteries. For daily use this is the only type to use.

Great "Cold Weather" battery. My outdoor weather station stopped reporting with the recent cold weather. I shifted to lithium batteries, per direction from the weather station manufacture, and my station is working again.

Excellent value. Yes, there are a lot of batteries in this package, but I use them in my digital cameras & in the transmitters for my indoor/outdoor thermometers. Plus the extended shelf life makes them an even greater value!

The 18 Pack of Energizer Ultimate Lithium is a great deal. The date of expiration is a long time, so you have plenty of time to use them. I have never had a problem with this brand or kind. They work great in my camera!

Great battery in extreme weather temperatures. Alkaline batteries leak and damage electronics, not these batteries. I will never buy another alkaline battery, but only lithium batteries for me.

I use these batteries in devices where I need to have the batteries last a long time. They work well with cameras, battery operated lights, outdoor weather sensors, etc.

I have outside security cameras that are power by batteries. The ultimate lithium outlast the standard alkaline batteries 3to 1 allowing a much longer change out time. Worth the extra money.

In Emergency Storage. When I put Duracells in storage over half had leaked in the package before half way to expiration date. Duracells have leaked in almost every application I tried.
