Pack of 5 Maxell SR626SW 377 Silver Oxide Watch Batteries Review

I tried different brands of watch batteries, these turned out to be optimal in terms of price / quality ratio. And for dozens of batteries at once, the price is just great!

Bought to replace the battery in the FreeStyle Libre 1 sensors for monitoring blood sugar. They work out stably for 14 days, but it is not always possible to restart after the expiration of 14 days

Has pros: Batteries outwardly look original, but have not yet been used in work . Some cons: There are no expiration dates on the individual battery packs or on the box.

Got pros: The silver battery is good because the clock turns off immediately, and does not start to lag behind like with other cheap batteries. Some cons: Batteries last for a maximum of 1.5-2 years. But the manufacturer claims that the service life is longer.

This battery was a replacement for my Timex day and date watch battery. This is a small tuff watch that works well when you have to work wet and dirty. I bought batteries and a watch kit to replace for less when my jeweler wanted to replace the battery. Changing the battery and closing the watch only took 7 minutes.

I don't yet know how to judge the durability as these are the first ones I've bought. The price was amazing - the best price I've ever found! They are opaque rather than transparent, which is why this category in the rating system confuses me. I installed them in the five hours I had and four of them worked right away as expected. The fifth had a different problem unrelated to the battery. I'm happy!

Works well in three different watches (also from different manufacturers) that were waiting for a battery change, so I assume a relatively common size is required. Got 5 batteries with plenty of time to expire (2022 I think) for about the same price as one bought locally. So far, all three clocks show a time of about 8 months. If batteries need replacing sooner than expected I will update my review. Arrived exactly as pictured.
