Everything You Need to Know About the LR1130 Battery

The LR1130 battery is a small, coin-shaped alkaline battery commonly used in compact electronic devices. Its popularity stems from its size, affordability, and sufficient voltage for low-drain applications. If you’ve ever used a wristwatch, calculator, laser pointer, or small electronic toy, chances are you’ve encountered this battery type. Understanding the LR1130 battery‘s characteristics helps ensure compatibility and longevity for your devices.

What Is an LR1130 Battery and How Does It Work?

The LR1130 is an alkaline button cell battery. It provides a nominal voltage of 1.5V and measures approximately 11.6 mm in diameter and 3.1 mm in thickness. As a non-rechargeable cell, it delivers a steady current ideal for low-power devices. The LR1130 follows the International Electrotechnical Commission (IEC) naming system, whereas similar batteries might have commercial names like AG10 or L1154.

Common Devices That Use an LR1130 Battery

• LR1130 batteries are widely used in:
• Digital thermometers
• Laser pointers
• Calculators
• Wristwatches
• Toys and novelty items
• Small remote controls

Their compact form and dependable voltage make them perfect for electronics that require a consistent but minimal power supply.

LR1130 Battery Equivalents and Cross-Reference Chart

The LR1130 battery is known by various names across brands and markets. Here are more comprehensive equivalents:

• AG10
• LR54
• L1154, L1154F, L1154G
• 189, 390A, 389A
• V10GA, D189, KA54
• GP189, RW89, G10A
• SR1130, SR54 (silver oxide variants)

These batteries typically share the same dimensions (11.6mm x 3.1mm), but their chemistry may vary—primarily between alkaline and silver oxide. Alkaline versions (like LR1130, AG10) are more affordable but have shorter lifespans. Silver oxide equivalents (like SR1130) are more stable and longer-lasting but usually more expensive.

LR1130 Battery vs L1154F Battery – What’s the Difference?

While the LR1130 and L1154F battery are often marketed as different batteries, they are essentially the same in core specifications:

• Size: Identical at 11.6mm diameter and 3.1mm height
• Voltage: Both deliver 1.5V
• Chemistry: Both are alkaline-based

The real difference lies in branding and naming conventions. “LR1130” is an international designation under IEC standards, while “L1154F” is used more often by specific battery brands like Duracell, GP, or Maxell. The suffix letter (F, G, etc.) may refer to packaging or production variations, not the electrochemical core.

In practice, these batteries are interchangeable. However, slight variations in internal resistance, shelf life, or brand-specific materials may lead to minor performance differences. It’s advisable to use matching cells within a single device, especially for multi-cell configurations like LED lights or laser pens.

LR1130 Battery vs SR626SW Battery – Can You Replace One with the Other?

These batteries differ significantly, and in most cases, are not interchangeable:

Key differences:

Size mismatch: SR626SW battery is much smaller in both diameter and thickness. It will not fit physically in an LR1130 battery compartment.

Chemistry and performance: Silver oxide cells like SR626SW are better for precision timekeeping like high-end watches due to their stable voltage and low self-discharge. LR1130 is better for general-purpose devices.

These batteries serve different needs and cannot be substituted for one another. If your device calls for LR1130, do not attempt to install an SR626SW, even if voltages seem similar.

LR1130 Battery Performance: How Long Does It Last?

The lifespan of an LR1130 battery depends on the device it’s powering and its usage frequency. Typically, it lasts between 6 months to 2 years. Alkaline batteries like the LR1130 tend to discharge more rapidly than their silver oxide counterparts, especially in high-drain applications.

Storage conditions also affect performance. Store LR1130 batteries in a cool, dry place to maximize shelf life and avoid premature discharge.

Conclusion

The LR1130 battery remains a dependable choice for many everyday electronics. Understanding its equivalents (such as L1154F), and distinctions from similar-looking cells (like SR626SW), helps avoid compatibility issues. When replacing batteries, always double-check the size, voltage, and chemistry to ensure safe and effective operation.

If you’re in doubt, refer to your device’s manual or consult with a technician. And when buying online, stick to reputable sellers to avoid counterfeit or expired stock.
