What pre-cycle process is involved before testing your batteries?
Before testing, we perform a pre-cycle by charging the battery at 0.2C5A at an ambient temperature of 25±5°C until it reaches the charge limit voltage. Then, we hold it for 0.5 to 1 hour before discharging it at 0.2C5A to the cut-off voltage.
Can you explain the charging and discharging test methods for your batteries?
We conduct standard charging and fast charging tests, ensuring that charging currents reach less than 0.02C5A within 8 hours. Discharge tests involve standard and rapid discharge methods, ensuring specific discharge times and capacities based on our battery specifications.
How do your batteries perform in extreme temperature conditions?
Our batteries undergo rigorous testing for high-temperature performance (at +70°C) and low-temperature performance (at -10°C), ensuring discharge capacities and safety standards are met under these conditions.
What safety protection features do your batteries have?
Our batteries are tested for overcharge protection, over-discharge protection, and external short-circuit tests to ensure they meet safety standards and do not exhibit hazardous behaviors such as fire, explosion, or leakage.
How do you ensure battery reliability during transportation and storage?
During transportation, our batteries are packed securely at a 30% load to prevent vibration, impact, or squeeze damage. They are designed to withstand various transportation conditions, including sea, land, and air transport, while also being protected from sun and rain exposure.
