IEC 61960-3

Meaning

Technical specifications establish the designation, marking, and performance requirements for secondary lithium cells and batteries used in portable applications. The iec 61960-3 standard provides a uniform method for measuring the discharge capacity and the internal resistance of cells under specific conditions. It ensures that consumers and manufacturers have a clear and comparable set of data for the batteries used in laptops, phones, and power tools.

The document covers everything from the initial state of the battery to the exact temperature of the testing environment to eliminate any ambiguity in the results.

Measurement Protocol

Discharge tests are conducted at room temperature using a defined current until the cut-off voltage is reached. The iec 61960-3 procedure mandates that the rated capacity be verified through a series of cycles to ensure consistency. This requirement prevents manufacturers from overstating the energy density of their products on the packaging.

Designation System

Identification codes are created to describe the physical dimensions and chemistry of the battery in a standard format. Under the iec 61960-3 framework, a code such as icr18650 provides information about the chemical composition and the physical dimensions of the cell. This naming convention is used globally to facilitate the sourcing and replacement of components across different brands.

Quality Benchmark

Minimum performance levels must be met for a battery to claim compliance with this international standard. By adhering to iec 61960-3, a supplier demonstrates that their manufacturing process is controlled and that their cells can withstand a reasonable number of charge cycles without excessive degradation. This compliance is often a requirement for selling electronic products in major international markets.
