Product Description The LR1130 is a compact, high-reliability button cell battery designed for small electronic devices requiring consistent low-power delivery. Often referred to as an AG10 or LR54, this 1.5V alkaline cell is the standard power source for precision instruments like digital watches, miniature calculators, small LED toys, and clinical thermometers. Its slim 3.1mm profile makes it the preferred choice for engineers and hobbyists designing ultra-thin wearable prototypes or compact sensor nodes.

Key Features

  • Standardized Form Factor: Direct replacement for AG10, LR54, 189, and 389 battery models.

  • Stable Power Delivery: Provides a steady 1.5V output, ensuring the accuracy of timing and measurement circuits.

  • Leak-Proof Technology: Robust stainless steel casing prevents electrolyte leakage and protects internal circuitry.

  • Efficient Energy Density: Packs significant energy into a miniature 11.6mm diameter footprint.

  • Broad Temperature Range: Reliable operation in various environmental conditions, from consumer electronics to industrial sensors.

Technical Details

  • Operating Temperature: -10°C to +50°C

  • Storage Temperature: 10°C to 25°C

  • Self-Discharge Rate: ~2% per year at room temperature

  • Terminal Type: Flat contact

  • Internal Resistance: Low resistance for consistent energy flow

Prototyping and Engineering Tips from Robogears

  • Stacking for Voltage: For projects requiring higher voltage, LR1130 cells are frequently stacked in series. For example, stacking three cells provides a 4.5V output, which is perfect for powering small 5V-tolerant microcontrollers or LED arrays.

  • Comparison with LR44: While the LR1130 has the same diameter (11.6mm) as the common LR44, it is significantly thinner (3.1mm vs 5.4mm). If your enclosure is too tight for an LR44, the LR1130 is your best alternative, though it offers lower total capacity.

  • Contact Maintenance: Always handle these batteries by the edges. Touching the flat surfaces with bare fingers can leave oils that increase contact resistance, potentially causing low-power devices to malfunction or reset.

  • Safe Disposal: As with all alkaline batteries, ensure they are disposed of at a designated e-waste collection point. Do not attempt to recharge these primary cells, as it may lead to swelling or leakage.

Package Includes

  • 1 x LR1130 1.5V Alkaline Button Battery
