Coin cell battery TESLA CR2430 — 3V lithium button cell, size CR2430

TESLA CR2430 is a 3V lithium coin (button) cell in CR2430 size designed for compact electronic devices. It provides a stable nominal voltage and reliable capacity for low-drain applications such as memory backup, real-time clocks, small remote controls and other portable electronics that require a thin, long-lasting battery in a compact form factor.

Advantages

The TESLA CR2430 delivers consistent voltage over its discharge curve and has low self-discharge typical for lithium chemistry, supporting long storage life before use. Its standardized CR2430 dimensions ensure compatibility with devices that accept this size, while the sealed metal can construction resists leakage under normal operating conditions. The cell’s compact diameter and slim profile make it suitable where space is limited and where a stable 3V source is required for intermittent or continuous low-current loads.

Suitable for

• Watch and clock backup power
• Motherboard CMOS / BIOS memory backup
• Key fobs and car remote controls
• Small calculators and portable measuring instruments
• LED indicators, sensors and other low-drain consumer electronics

Key specifications

• Nominal voltage: 3 V
• Chemistry: lithium manganese dioxide (Li–MnO2)
• Cell type: coin / button cell, CR2430 size
• Typical form factor: round, low-profile coin cell
• Intended use: low-drain and memory backup applications

How to use

Install the TESLA CR2430 in the device following the device manufacturer’s polarity markings, ensuring the correct orientation of the positive and negative terminals. Handle the cell with dry hands or appropriate tools to avoid shorting the terminals. Replace the battery when device indicators show low voltage or after the expected service life; discard used cells according to local regulations for battery recycling. Do not attempt to recharge, disassemble, heat above recommended temperatures, or expose to fire.

Usage recommendations

Store unused cells in a cool, dry place away from direct sunlight and metal objects that could cause short circuits. For devices with continuous memory backup needs, check device documentation for recommended replacement intervals and perform periodic checks to prevent data loss.
