CR2032 3V Lithium Coin Cell Battery (Micro Lithium Cell) — 240mAh | Lithium MnO₂ | 20mm × 3.2mm | –20°C to +85°C | 3-Year Leak-Free | Mercury-Free | Pack of 5

The CR2032 is the most widely used lithium coin cell in consumer electronics — standard for PC and laptop motherboard CMOS backup batteries (retaining BIOS settings and system clock when the computer is powered off), car key fobs and keyless entry remotes, digital watches, pocket calculators, personal organisers, small medical devices (glucose meters, thermometers), electronic toys, remote controls, fitness trackers, and scientific instruments. The 5-pack quantity suits home users, PC builders, IT technicians, and automotive service workshops requiring convenient batch replacement.

Lithium Manganese Dioxide (Li-MnO₂) chemistry provides a nominal 3V output with a flat, stable discharge curve — maintaining near-constant voltage through most of the battery’s life before a rapid drop at end-of-life, unlike alkaline batteries that decline gradually throughout use. The 240mAh typical capacity delivers reliable runtime for both continuous-use applications (car remotes, active medical devices) and low-drain standby applications (motherboard CMOS backup, watch timekeeping). Super Cell Technology ensures consistent internal resistance and voltage delivery across the full capacity for predictable device performance. The –20°C to +85°C operating temperature range covers all normal indoor and outdoor use environments — including cold weather car remote operation and warm ambient electronics enclosures. The 3-year leak-free shelf life ensures stored batteries retain reliability and will not damage devices during long-term installation. Mercury-free and environmentally responsible construction. The standard 20mm diameter × 3.2mm height (IEC CR2032) fits all devices specified for CR2032 batteries worldwide.
