Energizer Ultimate Lithium AA Batteries (4 Pack), Double A Batteries

I have an electric toothbrush that was using two regular AA batteries about every week and a half! I bought these lithium batteries, and have rarely had to change out the batteries. And, when I do have to change them in the toothbrush, they're still very strong and I use them in my clocks.

These batteries are great from wireless surveillance indoor and outdoor cameras. They last a very long time and are also recommended by many security camera manufacturers. So don’t try the off brand and stick with something that really works and doesn’t break the bank.

For those unfamiliar with battery chemistry here it is. Most alkaline batteries start out providing 1.5V of energy for a short while and then begin to drop down until they are so low on voltage they do not work. Lithium ultimates stay at a full 1.5V until completely dead. You get full use from new to dead. That is the advantage and why they are expensive.

Like them so well that we switched everything over to the lithium (long life) batteries in our home and office.

Lithium batteries are expensive but they definitely last longer than standard batteries. I buy them for my cameras.

OVERPRICED GARBAGE: 2 Months to Death ☠️ I keep notes about installation dates and death dates of Lithium Batteries. Literally, 2 months worth of juice is in these batteries that die when it's time to go bed. This happened at Amazon and Walmart. So, I know it's Energizer is trash quality. Do not buy. I've learned my lesson. Never again!!!!!!!! 🤬

I have Blink, unfortunately these are the only batteries one can use. I'm replacing batteries every two days! This is ridiculous! These are not cheap. They should last longer than 2 days. Energizier needs to get it together. They sure don't keep going and going!

Not a single one of the batteries worked on any thing. Threw many away before I realized all the batteries were no good. Bink system says use only these. Well obviously if the new batteries don't work then just can't use them. Will never buy again.

These batteries do not expire until 2028 so what’s the problem? They didn’t even last a month! I’m so tired of the price of everything rising but the quality of the product being put out, decreasing. Nothing is made to last, definitely not these batteries.

I put these batteries in my device February 6th today is February 21st and I just got a notification that my batteries are depleted! battery should last a lot longer than 15 days very disappointed!
