PKCELL CR1632 3V Lithium Coin Cell Battery 120mAh 16 x 3.2mm

3V Lithium Coin Cell for Watches and Remotes

The PKCELL CR1632 battery is a 3V lithium manganese dioxide coin cell for watches, car remotes, key fobs and CMOS backup. It measures 16.0 mm in diameter and 3.2 mm in height, and the rated capacity sits at 120 mAh. A nickel-plated stainless housing and a sealed crimp hold the electrolyte inside through years of storage.

Nominal voltage is 3.0 V, and the discharge curve stays flat until the 2.0 V cut-off. Manganese dioxide chemistry gives low self-discharge, so a cell left in a drawer still works after five years. Internal resistance remains low enough to deliver the pulse current that remote keyless entry and wireless sensors demand. The compact 1632 footprint fits holders built for this size.

Operating range spans -20°C to 60°C, which covers vehicle interiors, unheated stores and outdoor sensor housings. The cell contains no mercury or cadmium. PKCELL rates storage life at up to 10 years and quotes 3–5 years of shelf life under normal retail conditions. Certification covers UN38.3, UL, CB, KC, PSE and MSDS for transport and retail compliance.

What’s in the Box

• CR1632 3V lithium coin cell battery

Why Choose the CR1632 Cell

• The flat discharge plateau keeps voltage steady for watches and CMOS memory through the service interval.

• 120 mAh capacity supports key fobs and wireless sensors that draw short current pulses.

• The sealed crimp and nickel-plated case limit leakage risk in drawers and service vans.

• Mercury-free construction simplifies disposal and meets RoHS and UN38.3 shipping rules.

• The 16.0 x 3.2 mm format drops into standard CR1632 holders without adapters.

• Low self-discharge means stock held over several seasons still reaches rated voltage.
