FAQ
Q: What's the main product in ZKT?
A: Rechargeable battery. Li-ion, Lipo battery and power battery pack.
Q: What is overcharge?
A: After charge, tested the batteries' initial state and capacity. Charge to 10.0V at 3C current, then charge to 0.01C at CV mode. Observe changes in battery appearance.
Q: What is over discharge?
A: After charge, test the batteries' initial state. When the batteries are normal, discharge to 0V at 0.5C. Observe changes in battery appearance.
Q: Can I have a sample order?
A: Yes, we accept sample order to test and check quality. Batteries can be made as require.
Q: Do you have MOQ limit?
A: Yes, we have MOQ limit for mass production, but it depends on battery model. Please contact us for details.
Q: How about the lead time?
A: Samples will takes 5-7 business days. Mass production will takes 25-30 days. It depends on quantity.
Q: How about shipping and delivery time?
A: Generally, battery will be shipped via Express, such as DHL, TNT, FedEx and UPS, delivery time is 3-5 business days. Or DDP service, delivery time is 11-15 business days. Airline and sea shipping also available.
Q: What about after-sale service?
A: We will offer you 1 year guarantee. If there are any problems, please inform us, we will offer you positive solutions.
