These are definitely great for certain electronics where you need the lithium battery over rechargeable or alkaline. I use these in my wireless thermostat for my AC and it’s great. Before I was going through alkaline batteries like once a month and rechargeable just didn’t work. These last easily 6+ months Read more

As many reviewers say, it is important to use these for the right job. Simply putting these in a TV remote would be a complete waste of money due to thier price. However, when used in an apllication that requires increased performance, these batteries are completely worth the price you pay. 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. Read more

Good value. Lasts almost as long as Duracell but costs a little less. Some of the off brand batteries don’t last very long, so the appeal of low price goes away quickly. Read more

These batteries are NOT cheap. However, they are needed for my personal flashlight that could allow a 747 to land in the amazon jungle safely. Finding these online is always a trick but as they are needed, I will purchase again. Read more
