The Maxell CR1220 3V Lithium Coin Cell is a high-density, long-lasting power source designed for small, precision electronics. At Electrapac, we supply genuine Maxell batteries because of their legendary leak resistance and stable voltage discharge, making them the top choice for critical backup memory and medical devices.

Product Overview

The CR1220 is a lithium manganese dioxide battery. The "CR" signifies its lithium chemistry, "12" represents the 12mm diameter, and "20" indicates a thickness of 2.0mm. These batteries are engineered to provide reliable power in a wide range of temperatures, from -20°C to +85°C.

Key Features for Electrapac Customers

• Superior Shelf Life: Maxell’s advanced sealing technology ensures a shelf life of up to 10 years, so you can keep spares in your drawer without worrying about them losing charge.

• Stable Discharge: Maintains a consistent 3V output throughout its life cycle, which is essential for digital watches and CMOS motherboard clocks.

• Leak-Proof Design: Built with high-quality stainless steel casing to prevent corrosion and leakage, protecting your expensive electronic circuits.

• Environmentally Conscious: Maxell coin cells are manufactured with 0% Mercury, making them safer for the environment.

• Compact High Energy: Despite its tiny footprint, it packs enough energy to power micro-displays and low-energy Bluetooth (BLE) transmitters.

Installation & Care Guide

To ensure your device from performs at its best:

1. Handling: Avoid touching the battery surfaces with bare fingers. Skin oils can create high resistance and drain the cell faster. Use plastic tweezers or a clean cloth.

2. Polarity: Ensure the "smooth" side (marked with + and the model number) is facing the positive contact of your device.

3. No Recharging: This is a primary (non-rechargeable) cell. Attempting to charge it may cause leakage or damage.

4. Storage: Store in a cool, dry place away from direct sunlight and metal objects to prevent accidental short-circuiting.

Primary Applications

• Watches & Jewelry: Used in many slim-profile digital and analog watches.

• Motherboard Backup: Powers the BIOS/CMOS memory in some specialized laptops and industrial PCs.

• Car Key Fobs: Common in remote entry systems for various vehicle brands.

• Medical Devices: Reliable power for digital thermometers, glucose meters, and heart rate monitors.

• Calculators & PDAs: Found in many Casio and Sharp scientific calculators.
