The Maxell CR2032 3V Lithium Coin Cell is the most widely used button battery in the world. At Electrapac, we supply genuine Maxell batteries because they provide the reliable, long-term power required for everything from computer motherboards to medical devices and car remotes.

Product Overview

The CR2032 is a high-energy density battery that excels in providing low-constant power over long periods. The name reveals its physical size: 20mm in diameter and 3.2mm in height. Maxell’s lithium chemistry is specifically designed to handle high-pulse discharge, making it perfect for wireless devices like Bluetooth trackers and keyless entry fobs.

Key Features for Electrapac Customers

• Exceptional Shelf Life: Thanks to the low self-discharge rate of lithium chemistry, these batteries can retain up to 90% of their capacity even after 10 years of storage.

• Stable Operating Voltage: Unlike alkaline batteries, the CR2032 maintains a flat discharge curve, ensuring your device operates at peak performance until the battery is nearly depleted.

• Anti-Leak Technology: Maxell uses a proprietary sealing process that prevents the leakage of electrolytes, protecting your sensitive electronic circuits from corrosion.

• High Reliability: Manufactured to strict quality standards, these cells are resistant to vibration and shock, making them ideal for automotive and industrial use.

• Zero Mercury: These batteries are environmentally friendly and comply with global safety and environmental regulations.

Safety & Usage Tips

To maximize the life of your batteries purchased from :

1. Keep Clean: Wipe the battery with a dry cloth before installation. Fingerprints can leave oils that increase resistance and drain the battery faster.

2. Avoid Stacking: Never store loose coin cells together in a bag or drawer; if they touch, they can short-circuit and leak or explode.

3. Check Polarity: The "+" sign is clearly marked on the flat, smooth side of the battery. This should almost always face toward the battery cover or the spring contact labeled (+).

Primary Applications

• Computer Motherboards: Standard backup battery for the CMOS/BIOS settings.

• Smart Home Devices: Used in Zigbee/Z-Wave motion sensors, door sensors, and temperature monitors.

• Automotive: The standard battery for 90% of modern car key fobs.

• Health & Fitness: Essential for digital scales, heart rate monitors, and pedometers.

• Calculators & Games: Found in Texas Instruments, Casio calculators, and handheld electronic toys.
