Customers like the battery life of the tools. They say the batteries are long-lasting, do not leak toxic oil, and have a long shelf life. They also say the lithium cells not only make their flashlights last longer, they increase the brightness, and do not spill. Customers also mention that the batteries outlast regular alkaline cells by multiple times. They hold up great, store for much longer, and are very good as battery backups for hard-wired smoke and CO detectors.

Mostly, I use them for flashlights for camping and other tasks around the house. They not only make my flashlights last longer, they increase the brightness and will not fail in freezing temperatures. I own some pretty expensive flashlights also. The lithiums are far less likely explode or leak like alkaline have been known to do. It has happened to me and ruined a flashlight on me. That being said, I recommend these for your high-end electronics like digital cameras or two-way radios and the like. They will perform better and will not be ruined by a battery malfunction.
The other great thing for the camping aspect is the lightweight of the batteries themselves. This allows me to pack them into my system and not worry about weight as they feel seemingly hollow, almost cheaply light.
I highly recommend the Powerpax battery caddy sold here on amazon for storage in camera bags or your camping system. They keep them from coliding with each other and getting damaged. You can seem my in-depth review on these items as well to gain an idea of how well they function.
You can also buy these in bulk as the shelf life is 15-16 years as advertised. I can not vouch for this personally but it is an intriguing idea for sure.
Also, I beleive the 12 packs sold in Sams Club are the best deal I've found as each battery came to be $1.67 a piece. However, sometimes the prices on amazon drop and they become a better deal and vice versa.
Overall, I highly recommend these batteries for those tasks that demand performance. They are worth the price and will keep your expensive electronics safer.
