Key Considerations for Wholesale Purchase of 1500mAh 18650 Batteries
Verifying the Authenticity of Technical Specifications
Some low-priced products on the market may falsely claim higher capacities. When procuring in bulk, pay close attention to the following:
Actual Discharge Capacity: When tested with a 0.2C constant current discharge to 2.75V, a genuine 1500mAh battery should deliver a minimum capacity of 1450mAh.
Internal Resistance Consistency: In bulk purchases, the difference in internal resistance between individual cells should be less than 5mΩ to prevent uneven heating in battery packs.
Cycle Life: Under standard conditions (25°C, 0.5C charge/discharge), the battery should retain ≥80% of its capacity after 500 cycles.
