Yes, we are. You are warmly welcome to visit our factory if you’d like to know us better.

In the battery,during the recoil energychemical reactions take place.When operating in sub-zero temperatures the process is slowed down, the consequence is a decrease battery performance.When used in temperatures above zero, charge and discharging recovers.

There is no single answer to this question. Battery lifetime depends on how well she enjoyed.We can not allow a full battery discharge overcharge, and charge higher current than specified by the manufacturer. If you do not violate the

manufacturer's recommendations and rules of operation, the number of cycles of charge|discharge will be at least 300.

Yes, it is. Please feel free to tell us your application and your basic battery reguirements. Our R&D team will provide a full solution to you with these factors taken into consideration: working temperature, dimension, compound mode,power. capacity, peak current, PCM, fuse motion controlI connectors.

Yes, we can, please discuss with our sales and engineer. We also ask client to order a sample to test our battery quality first.

Sample needs 5~10 days, mass production time needs 3~5 weeks, it depend on order quantity.

Yes, we have MOQ for mass productionit depend on different part number.  Regular battery we can afford 500pcs, customized batteries, MOQ will be 5000pcs.

We usually ship by DHL,UPS,FedEx or TNT. It usually takes 3-5 days to arrive Airline and sea shipping also optional.

Yes. Please inform us formally before our production and confirm the design firstly based on our sample.

To ensure the long-term (more than a month)storage battery you need to follow some simple rules: Transfer to battery-storage mode(3.8 V-3.9V); During storage, once a month,check the voltage with a voltmeterlf the voltage is different from 3.8 V-3.9V, recharge to the required performance;Store in a cooldry place with a temperature of 5-20℃. To maximize battery performance closely matched the factory do not recommend storing batteries for over a year. We hope that these recommendations will help you to always be ready to work even after a long break.
