The Energizer lithium batteries are more expensive, but they last much longer than Alkaline batteries. So the price sort of balances out, and I don't have change batteries as often.

I use these in equipment, flashlights, toys ... anywhere I need more power (i.e., longer use life) and NO LEAKS! Yeah. Beats the copper tops all the way around.

These Lithium batteries are Strong and long lasting. I use them in all my security cameras and they last a couple years each. Very Dependable. I got the best price possible at Sam’s Club.

Bought the lithium batteries as they were recommended to withstand the heat. So far so good as the heat has been over a 100 every day for awhile now. Still seem to be as fresh as they were when I bought them.

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.

I purchased these because my Nest fire alarm sensors will not allow rechargeables; I found these holding a great charge and that is why Nest requires them.

These are excellent long life batteries. They will go much longer than regular batteries. They are really the only batteries you can use in Blink cameras. As such I buy these batteries pretty frequent, and I've never been disappointed.

These batteries... I just dont know how I functioned day to day without These batteries! You simply put them in whatever it is that needs a battery, turn it on. Like magic the item works. Its magic I tell you, Magic

These batteries are used in security cameras and last a very long time even though they are subjected to all weather conditions. Definitely worth the price.

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.
