Button Battery ANSI C18.3M Testing Service

ANSI C18.3M is a safety standard for portable lithium primary batteries (including button cells).

The main testing items include:

Electrical Performance Tests

- Voltage Test: Measure the open-circuit voltage to ensure it meets the rated voltage.

- Capacity Test: Determine whether the actual capacity of the battery meets the rated value through discharge testing.

- Discharge Performance Test: Evaluate the battery’s performance under different discharge conditions.

Mechanical Performance Tests

- Impact Test: Simulate impacts the battery may experience during transportation or use.

- Vibration Test: Assess the battery’s stability under vibration conditions.

- Crush Test: Check the battery’s safety when subjected to compression.

Environmental Tests

- High-Temperature Test: Evaluate the battery’s performance in high-temperature environments.

- Low-Temperature Test: Evaluate the battery’s performance in low-temperature environments.

- Temperature Cycling Test: Assess the battery’s stability during temperature fluctuations.

Safety Tests

- Short-Circuit Test: Simulate the battery’s reaction to a short circuit to ensure no hazardous events occur.

- Overcharge Test: Evaluate the battery’s safety under overcharging conditions.

- Forced Discharge Test: Test the battery’s behavior during forced discharge.

Labeling and Packaging Tests

- Label Inspection: Ensure that the battery labeling complies with standard requirements.

- Packaging Test: Assess the protective performance of packaging during transportation.

These tests aim to ensure the safety and reliability of button batteries under both normal and abnormal conditions.
