Questions about this item

Does the 3-pack include any extra tools or holders, or just the three 303/357 cells?

The pack contains only the three silver-oxide 303/357 button cells; no tools, holders or adapters are supplied.

Should I choose the 303 or the 357 version for my watch or calculator?

Both numbers refer to the same 1.5 V silver-oxide coin cell, so either designation fits devices that call for a 303 or a 357.

Will the 1.5 V rating stay steady in a glucometer or car remote over time?

Silver-oxide chemistry delivers a stable 1.5 V output throughout most of the cell's life, which is why it is specified for glucometers, calculators and car remotes.
