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.
