Energizer 40AA Ultimate Lithium Long Lasting Leakproof Batteries

We have one of those awful Nest smoke detectors. Any other type of battery has to be changed at least once a month. These are the ONLY batteries that last. We installed them about five months ago and they are still working. Yes they are more expensive, but they are also less frustrating. I'm sure we are saving money in the long run.

I had a slight problem with a few batteries and I contacted the seller and they immediately sent out replacements. Great customer service.

I bought these for our family room shades. They last a decent length of time and work to raise and lower the oversized shades. We use the shades daily and only have to replace the batteries about three times a year. They are rather costly but you definitely get a quality product if you pay a little more.

Long battery life and compatible with my security cameras.

I wish they lasted longer in our Blink Cameras. THe bitter cold is not helping but it is expensive upkeep to keep them going.

Good product. No problems.

These batteries are more expensive, but they last along time. We use the AA size most of the time , for outside cameras even in winter they last 6 to 8 weeks.

I've been using these batteries for sometime. I accidentally bought a whole package. The last battery I put in a clock lasted one week. Of the 20 batteries I purchased 10 of them have so far been totally worthless. They have not worked at all. I just used another battery two days ago in a clock. It's now dead after only two days. So far out of all these batteries 10 have failed.
