5 Pcs CR1620 CR 1620 - 3V Eunicell Lithium Button Cell Battery Batteries - BRAND NEW IN FACTORY PACKAGING

I found this CR 1616 3-volt button cell battery in an old watch at home it could be found in calculators cameras whatever and I've always wondered if the store doesn't carry 16 16 battery can I replace this with another one that's different number but close in size so this is what I did to figure this one out I measured the battery's diameter it is just so happens to be an almost 16 millimeter battery and this happens to have a thickness of about 1.7 million meters something like that this is good 1.7 1.8 whatever something like that and if I throw it on a scale that's measuring this is a jewelers scale basically let's measure it in grams if I throw it on it it's 1.1 grams so in the store what I find sometimes instead of 16 16 years 16 20 I took it out of the package and it just happens to be the same diameter oops sorry the same almost 16 millimeter diameter and its thickness is 1.9 in
