What buyers say about LiCB CR1620 3V Lithium Battery CR 1620 10-Pack
I gave the 5 star rating on good faith, but I can't say for certain if the battery life will last or not, but I know this battery works well for a jewelers loupe.
Good quality and fast shipping, less expensive than other brands, and last as long as I want, if not longer, I am happy with the quality and longevity of the batteries.
I bought these for my phone and they seem to work well, even though I use the phone a lot.
If you can't find them in the store, you'll get them for twice the price, which is the best price around.
The batteries are packaged and fresh, which is worth the money compared to going to the store.
