I use this batteries for a device to give my self a boost of pain medication through a pain pump implanted in my body hooked to a catheter into my spinal cord up to 10 times a day and I used to get Duracell AAA and only lasted one month when I got this batteries I changed them and I been using them and no one single bar of the charge has dropped since I put them on. BIG DIFFERENCE.

- Energizer Ultimate lithium batteries cost about 3 times the cost of alkaline batteries; however, they are more cost-effective. - They never leak and destroy a device. - They hold the charge for about 10 years or more at room temperature, and, longer if stored in refrigerator. - You can put them in a flash light, store the flashlight for 10 years, pick it up and it will turn on. - Energizer Ultimate lithium batteries operate much better in cold climates and hot climates than alkaline batteries. - Energizer Ultimate lithium batteries are lighter in weight. - Energizer Ultimate lithium batteries have a useful charge (amp hours) of about 3 times that of an alkaline batteries. - They provide a higher voltage as the battery is used. - Energizer Ultimate lithium batteries save your time, because, you do not have to replace them as often and do not have to replace devices because of battery leak. - They are more dependable, because of the longer storage life, extreme hot and cold temperature capability, leak proof, and, larger storage capacity. - These Energizer Ultimate lithium batteries are the throw-a-way type, not, the rechargeable type. - These Energizer Ultimate lithium batteries have a voltage, when new, of about 1.7 volts, so, they will work with most any device that also works with an alkaline battery. - Summary: They cost more, but, they are more cost-effective when all factors are considered.

The Energizer Ultimate Lithium are at the top of the list for batteries that work in the cold. Nothing else works as well in the cold. WalMart has great accuracy for a battery order. Amazon messes up battery orders, but not WalMart.

Execelentcprod7ct, great price!!!

Doesn’t work with all products. I have found that the battery stays good but my product quits working. This includes the controller for my fireplace and the battery operated lights at Christmas. I won’t buy again.

Always great batteries. Just like most greedy manufacturers, the price is jacked up way too high.

Used them for 9 days to light up outside led wreaths. They all went dead. Advertised good to 40° below, couldn't handle 20°. Failed faster than regular Energizer batteries.

These batteries will leak sooner or later. Energizer will not help. Our batteries were terrible and leaked into our unit.

I bought 18 pack of these lithium batteries in December 2023, it is now April 2024 and half of them are dead? Not pleased with this purchase.
