I’ll have another 4 years, reliable use of my Nest Protect because I rely on Energizer Lithium batteries. A little pricy but very long service life and never leak other kinds of batteries.

when you are putting your homestead and occupant's life on the line every night, having a working smoke detector is worth the price. One of the sadest finding at a fire scene, is the smoke alarm dangling by its wires, having had the batteries taken out because the alarm kept beeping a "low battery" alert

Expensive but very good batteries, probably the best you can get

Great battery a little pricey. Good value if you're needing something to use power for a while.

Lithium batteries are the only batteries i can use in my cameras. I must say that they last a long time

Great brand and buy for the amount of batteries you get because they last a long time.

Long lasting for the price. This is the only batteries we buy.

These batteries really last a long time!!! I am pease with purchase Would recommend

The batteries are durable and are working well. The manager Dylan was able to assist me and to make sure all is well.

Superior shelf life and power, especially in cold temperatures, but expensive

I took my time to really think these were worth buying the past couple years. They are now more cost effective I still will use the standard AA in many other areas. But this is my first and only choice for cold weather usage. My trail cameras and outdoor weather sensitive equipment is such an important factor. The bottom line is lithium batteries are truly superior, performance voltage last so much longer!

Bought this for our friends, for their outdoor surveillance camera. They installed quick and easy, without any problems. Time will tell, but they are supposed to last a few months. All in all, they seem good quality. They were available at our local Best Buy.

Camera Ready, great brand long lasting battery life

The longest lasting no leak battery I have found and I tend to go through quite a few

If you use the blink camera, you know these batteries last the longest and gove you the best performance. There costly but worth the value.

Served their purpose. What more can I say about batteries????????????

These are the only batteries I will buy for my higher end devices and are definitely better than the regular AAA batteries. Yes, they cost more than standard batteries but the performance cannot be compared. They last longer and do not leak if you forgot about them being in the device, like regular batteries tend to do.

Always a product that I carry with me on the road. Never know when you might need them.

I LOVE THESE THEY LAST ABOUT FOUR TIMES AS LONG AS ANY BATTERY I HAVE USED IN THE PAST

Pricey but worth it. I use these for wireless lavalier Shure mic... the regular alkaline AAs just don't have enough juice to make it through a 2 hour broadcast without faltering. Tried other cheaper brands and will not try again... it seems that Ultimate Lithium holds PEAK power the best and mic doesn't falter.
