Battery Sample Request Strategy: How to Efficiently Verify Supplier Product Quality

Select 2-3 capacity tiers for comparative testing based on device requirements. For example, smart lock manufacturers should request AA 1.5V lithium battery 2775mWh and 3100mWh tiers simultaneously, test runtime in actual devices, and select the best cost-performance tier.

If devices have multiple models, recommend requesting samples for each model. Different devices have different power consumption characteristics, same battery may perform very differently in different devices.

Basic tests: Capacity verification (actual vs rated capacity), voltage testing (open circuit and working voltage), internal resistance testing.

Performance tests: Cycle life test (charge-discharge cycles until capacity degrades to 80%), high/low temperature performance test (discharge at -20°C and 60°C), charging speed test.

Safety tests: Overcharge test, over-discharge test, short circuit test, crush test. Recommend commissioning third-party laboratory for objectivity.

JYOVEX provides free sample service, regular models can be applied directly, custom models need 3-5 day prototyping after requirement confirmation. Samples shipped with bulk orders are free of charge. Samples come with complete test reports including capacity, internal resistance, voltage data.
