Witness Lab Testing in Action

Vibration Resistance Testing for Batteries

We frequently simulate vibration conditions

to examine the battery's stability and durability under sustained vibration.

High-Precision Analysis of Raw Materials

Using atomic absorption spectrometry, 

we precisely measure trace element content in materials to ensure purity and consistency from the source.

Tensile Strength Testing

We perform tensile strength tests on battery separators 

to evaluate their tensile strength, elongation, and mechanical integrity, 

ensuring the safety of the battery's internal structure.

Temperature Control & Pulse Charging Test

Using high-frequency pulse charging in a constant-temperature environment, 

we evaluate charging efficiency, temperature rise behavior, and thermal management response.

Low-Temperature Performance Testing

Batteries are placed in extreme conditions of -35°C to test discharge capacity retention, 

internal resistance changes, and cold-start capability, 

verifying reliability in frigid environments.

Smart Charge-Discharge Cycle Testing

Using a multi-channel cycling test system, 

we monitor real-time capacity fade, voltage behavior, and lifetime trends during long-term cycling.
