1. Q: Where can I get the price?
A:,We usually quote within 24 hours after we get your inquiry. If you are very urgent to get the price,
please call us or tell us in your email so that we'll regard your inquiry priority.
2. Q: How can I get a sample to check your quality?
A: After price confirmation, you can require for samples to check our quality.
3. Q: What about the lead time for mass production?
A: It depends on your order quantity and the season you place the order.
Voltage instrumentation requirements--Measuring the voltage meter accuracy no less than 0.5 magnitude; Current instrumentation requirements--Measuring the current meter accuracy no less than 0.5 magnitude; Time instrumentation requirements--Measuring the time meter accuracy no less than 0.1%; Temperature instrumentation requirements--Measuring the temperature meter accuracy no less than 0.5 ℃; Impedance instrumentation requirements--Measuring impedance should by sinusoidal alternating (1 KHZ) test.
6. Q: What is full charged?
A:With charging voltage 4.2V, current 0.2C continued to charge the battery pack, when charging current
drops to 0.02C charging is terminated, shall be full charged.
7. Q: What is full discharged?
A: Standard discharge current 0.2 C for continuous discharge, when the voltage drops to discharge cut-off voltage 3.0V discharge is terminated, shall be full discharged.
8. Q: If your specification can not meet my requirements, can you design and build my battery?
A: Of course. We will design and build your own products according to your special requests.
9.Q: What is minimal capacity?
A:,The capacity means the discharge capacity of the cell, which is measured with discharge current
of 0.2C with 3.0V cut-off voltage after the standard charge.
10.Q: What is typical capacity?
A:,The capacity means the average discharge capacity of the cell, which is measured with discharge
current of 0.2C with 3.0V cut-off voltage after the standard charge at 23±2℃ environment
11.Q: What is retention capability?
A:,After full charging, storing the battery 28 days with 20 ± 5°C condition , and then staying 1 hours with
discharge current of 0.2C till 3.0V cut-off voltage.
12.Q: What is standard charge?
A:,Charging the cell initially with constant current at 0.2C and then with constant voltage at 4.2V till charge current declines to 0.02C.
