8 Channels Coin/Button Cell Testing Board

8 Channels Coin Cell Testing Board GN-TB – Button Battery Test Holder for <25mm Cells

The GN-TB Eight-Channel Button Battery Test Holder is a versatile fixture designed for performance testing of button/coin cells with diameters less than 25mm (compatible with CR20xx series including CR2016, CR2025, CR2032, CR2430, CR2450, etc.). This test board allows simultaneous testing of 1 to 8 batteries, significantly improving testing efficiency in laboratory and quality control environments.

Physical Layout:

The test board features 8 independent channels, each clearly marked from BATTERY1 to BATTERY8. Each channel includes:

• BAT+/BAT- Binding Posts: Red terminal for positive output, black terminal for negative output
• Tact Switch (SW): Non-self-locking button for polarity/contact verification
• LED Indicator: Lights up when switch is pressed if battery is correctly installed and has power

Operating Principle:

1. Battery Installation: Place the button battery with positive pole facing up into the designated annular area. Ensure the battery is centered and makes good contact with both upper and lower pole pieces.
2. Polarity Verification: Press the corresponding tact switch (SW). If the LED lights up, the battery is correctly installed and has power. If not, check polarity or battery charge.
3. Analyzer Connection: Connect the battery analyzer to the binding posts using appropriate cables (available separately).
4. Testing: After connections are verified, set test parameters on the battery analyzer and start the corresponding channels.

Key Features:

• 8 Independent Channels: Test up to 8 batteries simultaneously with individual controls and indicators
• Quick Polarity Check: Non-self-locking switches with LED indicators for instant verification
• Universal Compatibility: Accepts all button cells with diameter <25mm (CR20xx series, CR24xx series, etc.)
• Clear Binding Post Connections: Red/black terminals for secure analyzer connections
• Easy Battery Loading: Simple drop-in design with annular contact areas
• Compact Design: Space-efficient benchtop footprint for laboratory use

Compatible Cable Options (Purchased Separately):

1. Four-core aviation plug to banana connector cable
2. Two pairs of alligator clips (positive/negative) with banana connector cable set
