CMOS battery PKCELL CR2032 Lithium 3V CR2032

CMOS Battery PKCELL CR2032 Lithium 3V

The PKCELL CR2032 is a lithium manganese dioxide (Li/MnO2) coin cell with a nominal 3V and 210mAh capacity, 20 mm in diameter and 3.2 mm thick. It is the most common size for the CMOS battery on desktop and laptop motherboards.

When the CMOS battery runs low, the computer loses the time and BIOS settings every time it is unplugged. Replacing it with a fresh cell solves that. The battery also fits remote controls, watches, car keys, calculators, wireless sensors and small medical devices.

According to PKCELL, the cell has a self-discharge below 5% per year, a 5-year shelf life and an operating range of -20 to 60°C. It is mercury-free, has no memory effect and passes short-circuit, drop and vibration tests. Sold as a single piece.

Key features

• 3V and 210mAh - Nominal 3.0V and 210mAh capacity (15kΩ load to 2.0V cut-off), about 1100 hours of continuous discharge at this load.
• For CMOS/BIOS - The standard size of the motherboard backup battery that keeps the clock and BIOS settings while the PC is unplugged.
• Low self-discharge - Less than 5% capacity loss per year and a 5-year shelf life, so it can be kept as a spare.

• Safe and clean - Mercury-free with no memory effect. According to PKCELL, cells are tested for short circuit, drop and leakage with no fire, explosion or leaks.
• Many uses - Remote controls, watches, car keys, calculators, wireless sensors, electronic toys and small medical devices.
