I’m always running around trying to see what I can remove a battery from for the Grandkid’s toys. Now, I have plenty. Seems like the CR2025 is a popular voltage for a variety of items. I also use these for my tea, votive and pillar candles. I will admit the packaging needs to be better for each individual pack. Luckily, these were all put together in a ziplock type of plastic bag, and all the individual batteries were contained in the bag, otherwise it would have been a bad. I repackaged each one and secured it with tape because my husband said these can short out if touching. So better safe than sorry. Honestly, my husband gets a little perturbed whenever I tried to buy some of these, but he couldn’t argue with me on this deal. I got the thumbs up! Nothing much more to say other than they work, were delivered on time and I have had no issues other than the packaging.
