No Sew CR2032 3V Lithium Battery 20 Pack

Pack Contents and Intended Use

This pack contains twenty CR2032 lithium manganese dioxide button cells, each rated at 3 volts and 210 milliampere-hours. They are designed for small electronic devices such as watches, calculators, car key fobs, computer motherboards and Bluetooth trackers. The individual blister packaging allows single batteries to be removed without exposing the rest. This product is not suited for applications that require rechargeable cells or higher capacity formats.

Storage Life and Leak Resistance

The chemistry provides a long shelf life with minimal self-discharge, so cells remain ready for occasional or seasonal use. PKNOVA states that extensive pre-release testing ensures leak-free operation under normal storage and operating conditions. The resistant blister pack adds a physical barrier against accidental ingestion. No thermal management or active cooling is relevant for these low-drain coin cells.

Sustained Low-Current Performance

Under the continuous microampere loads typical of CMOS memory backup or remote-entry circuits, the 210 milliampere-hour capacity delivers multi-year service intervals. Voltage remains stable throughout most of the discharge curve, avoiding the sudden drop-off seen in some alkaline alternatives. The pack is not intended for high-drain devices such as LED flashlights or motorised toys where rapid depletion would occur.
