- Reviewed in Canada on March 19, 2025Verified PurchaseI needed 3 LR932 button cell batteries and those are only available from limited number of sources at absolutely ridiculous prices. The cheapest I found would cost me US $30 for three button cell batteries. As some people may probably know, A23 battery is a dry-cell container that has 8 LR932 button cells wrapped inside. All you need to do to get them out is to carefully open A23 on the seam and get your LR932 button cell elements. I've got 8 LR932 batteries for CAD $4. All with voltage around 1.56-1.58V the way they should be. You need to be careful doing that and of course it's totally up to individual preferences but for me this was a super convenient and efficient solution.

- Reviewed in Canada on February 18, 2025Verified PurchaseWe have a very old garage door opener that came with the house & we have never used it before...until this winter with so many snowstorms we decided to put vehicle in garage.
This battery 2pk at stores where I live is almost $15 and generic brand, found these on 鶹 & they fit great, and now its easy to use the opener and not have to get out of vehicle to close garage door.

4.0 out of 5 stars This is difficult to review.
Verified PurchaseI ordered these batteries for a small crystal clock that had stopped. They’re definitely the exact ones needed but when I put them in, nothing happened.
Since I don’t have anything else that uses this size battery, I don’t really know if the batteries aren’t viable or if it’s the clock itself. So I hesitate to write a review since I obviously can’t give 5 stars but don’t want to disparage the product if it’s clock that has working issues. Therefore, reluctantly opted for not quite perfect but hopefully good.
