FAQ

Q: Are you a factory?

A:Yes, our factory was established in 2010. We focus on the battery field and are a high-tech battery enterprise integrating development, production, and sales.

Q: How to revive a completely dead Li-ion cylindrical battery?

A:Perform a few charge and discharge cycles to help restore the battery's capacity. Fully charge the battery, then discharge it using a controlled load until it reaches its cut-off voltage. Repeat this process a few times. This can help to recondition the battery and potentially recover some of its lost capacity.

Q: What certifications do you have?

A:Our Cylinder Battery batteries have passed CE, RoHS, SGS, CNAS, MSDS, and UN38.3 certifications.

Q: What is your lead time?

A:It depends on the order quantity and the season you place the order. Usually we can ship within 7-15 days for small quantity,and about 30 days for large quantity.

Q: What is the minimum order quantity?

A:For our Cylinder Battery, the minimum order quantity is 20 pieces, but smaller orders are also welcome.

Q: What is your after-sales quality guarantee?

A:Our quality control department will inspect each battery individually before shipment, ensuring 100% high quality. As a trusted battery brand with 15 years of experience, Greatech will replace any defective battery free of charge if any quality issues arise.

As one of the leading cylinder battery manufacturers and suppliers in China, we warmly welcome you to buy high-grade cylinder battery from our factory. All customized products are with high quality and competitive price.
