Button Lithium Battery MAXELL CR1632 3V — Coin Cell for Watches, Key Fobs, Calculators

MAXELL CR1632 is a 3V lithium coin cell designed for small electronic devices that require a compact, reliable power source. The battery delivers a stable nominal voltage of 3 volts and is intended for applications where long shelf life, low self-discharge and consistent performance are important. Its compact diameter and thin profile make it suitable for use in watches, key fobs, calculators and other portable electronics that accept the CR1632 size and 3V rating.

Advantages

This MAXELL CR1632 battery offers stable voltage output throughout most of its usable life and features low self-discharge for extended storage. The lithium chemistry provides higher energy density compared with alkaline or silver-oxide alternatives of similar size, resulting in longer runtime in low-drain and intermittent-use devices. The coin cell format ensures a compact fit and straightforward replacement in devices designed for this size.

Suitable for

• Wristwatches and digital timepieces
• Remote key fobs and car remotes
• Calculators and small handheld electronics
• Fitness trackers and small medical devices (where CR1632 and 3V are specified)
• Backup power for memory circuits and CMOS in compact electronics

Key specifications

• Nominal voltage: 3 V
• Chemistry: Lithium manganese dioxide (Li-MnO2) coin cell
• Cell format: Coin / button
• Typical use: Low-drain and intermittent-load devices
• Physical profile: Thin, compact diameter suitable for CR1632 compartments
• Storage characteristics: Low self-discharge for long shelf life

How to use

Install the battery with the correct polarity indicated in your device: the positive (+) side typically faces outward and the negative (−) side contacts the spring or holder inside the battery compartment. Ensure the device is powered off before replacing the cell, and handle the battery with dry hands or use non-conductive tools to avoid shorting. After installation, verify device operation and properly close the battery compartment. Dispose of used cells according to local battery recycling and hazardous-waste regulations.

Usage recommendations

Store unused MAXELL CR1632 cells in a cool, dry place away from direct heat and sunlight. Do not attempt to recharge, heat, puncture or disassemble the battery. Keep out of reach of children — coin cells can pose a swallowing hazard. For best device performance, replace batteries when device indicators show low power or when device behavior becomes erratic.
