GutAlkaLi CR2032 Lithium 3V Battery, Electronic Coin Cell Button for Toys Calculators Watches (40 Pcs)

I was very satisfied with these batteries. I need them for my fairy lights and the price was fair. I'm pretty sure they last 72 hours per battery and the ease of installation was fairly easy.

These batteries are great for the little Christmas candles. They last for a long time

The major brand "might" last a few hours longer than these but.... ONE of these costs four times less than the major brand. I don't mind changing them a bit more often when I'm saving more money.

Luckily I purchased several packages of 5 batteries, I purchased extra because, 1. I thought it was a better value and 2. I thought that I received enough batteries to last the holiday season, (I have several strands of “fairy” lights), but I was wrong. The batteries only lasted maybe 15 hours and I wanted them to go around our wreathes in the house and on the front doors. So I would turn the lights on, (they have an on off button which is good), when I got home for the day around 5:30pm and turned them off when I went to bed so they stayed on around 5 or 6 hrs pr day. So, I had to change the batteries every 3 days or more depending on when I returned home and when I went to bed and, obviously, if I forgot to turn them off before bed I needed to replace the batteries everyday. Each strand of “fairy” lights take two batteries that looked like the batteries you use in most watches but they are about nickel size and I have many watches that take “flat” batteries and I can wear my watches for over a year, or more, before I have to change them and they are working 24/7. I think that these light batteries should work throughout the Christmas season at least which is, for me, the 1stt week of December till the 1st week in January or around 29 days. I don’t know if the batteries or the “fairy” light strands are the issue but one of them has to be at fault, so I can’t really tell you which item is the issue. However, the light strands, when they’re 1st turned on are very pretty and bright.

Perfect, as described and I went through 3 packs the day I bought them filling up my fairy lights that I used in a bunch of projects I had just finished and had bought the WRONG batteries for the first time at Dollar Tree! These came the NEXT DAY when I ordered them so that was perfect! All 3 packs that I opened and tested worked fine, no duds! I do sell the projects I use them in, so I only make sure they work and stick them in my booth, so I do not know how long they last, but I did have a set on for a couple hours, so I know they last that long! These batteries in general do not last forever anyways and the projects they are in are meant to be turned off and on as needed! Hope this helps, Id def buy them again!

This is a whole heck of a lot of batteries for the money. Don’t let the pseudo electrical engineers lecture you about this or that battery having a half life as great as strontium 238. These are awesome and work great. Trust me (I didn’t say “Believe me”, that’s different), buy these and you’ll be really happy. I am. I just hope I live long enough to use them all. It’s not looking like a good bet. I’ll take the other side. It’s like playing the “Don’t Pass” line. Psychologically difficult, but smart.

This a great find. I have small battery operated candles that i use ALL the time and buying these in bulk saves me money.

I needed these to replace the battery in a led light strand on a holiday tree that I wanted to leave on for extended periods of time. After the battery died out almost immediately I grabbed a two pack at the grocery store and they too, didn’t last very long. I needed a much cheaper option! Ordered this bulk pack and was so impressed. Lasted longer than the Duracells I picked up at a local store AND were so much more inexpensive to order here.
