No Sew Cr2032 20-pack 3 V lithium standard battery

20-pack 3 V lithium coin cells

This pack contains twenty CR2032 coin cells rated at 3 volts and 240 mAh each. They use lithium metal chemistry with a low self-discharge design and a 5-year shelf life. The cells measure 20 mm by 3.2 mm and weigh 0.61 g. They are non-rechargeable and built with a leak-resistant seal.

Ideal for watches, calculators and medical devices

These cells suit devices that require a single CR2032 button battery such as watches, calculators, key fobs and small medical instruments. The 20-count pack covers multiple replacements or spares. Buyers who need rechargeable cells, higher capacity formats or larger cylindrical batteries should look at other chemistries and sizes.

240 mAh capacity per cell

Each cell delivers 240 mAh at 3 volts, which determines how long it will power a given device before replacement. The manufacturer states an energy density increase of 10 % and a monomer capacity increase of 20 % versus a normal cell, plus up to 50 % longer run time than basic alkaline in demanding devices.
