🔋 Duracell D389/390PK Silver Oxide Watch/Calculator Battery - Pack of 4 Review

The batteries fit well and got my calculator/watch working again. There are no issues with the packaging, or with the voltage (I measured it), or with an expiration date. The price was right.

I've ordered these many times for the lighted magnifying glass my mom uses for reading. I've always gotten 4 of these for the price and as far as I know never gotten a bad one. Usually I order from 12 pieces.

I use these batteries for my extinguishing knife which has an internal light. Although all phones have a flashlight, I always carry one because it has all the features, including ten pointing the stylus at the flashlight so you can write in the dark.
