A: CFE has 13 production lines with a total capacity of 12Gwh for both storage and E-mobility.

Q：How long is the warranty period?

A： Our limited warranty is valid for a period 5 years (12.8V products) /10 years (51.2V products) after delivery. It is restricted by specifications and warranty terms.

Q: How long is the estimated delivery time?

A: The delivery time is within 25 days after receiving the payment.

Q: Are you able to handle shipment transportation?

A: We can arrange the shipment to most places as required.

Q: What kind of certification do you have?

A: We have SGS, TÜV, IEC 62040-1, IEC 62109-1, IEC 62109-2, IEC 62619, UN38.3, IEC 62133, CEC, UL, MSDS, ISO 9001 certifications, but each product may be different.

Q: What kind of product quality your factory offer?

A: We provide the most competitive products at the highest quality. (100% cell sorting test under inner resistance ≦2mΩ, voltage differ ≦ 2mV,100% EOL test, 100 % aging, 100% final product testing) .

Q: Can we print our logo on products?

A: We can provide one to one customized OEM with a MOQ demand.

Q: What is the validity of the quotation?

A: Due to the raw material price fluctuation, the quotation validity is 10 days.

Q: How to determine the battery is good or bad?: General side maintenance has an observation hole if it is green to prove that the battery is normal if it is black to prove that the battery does not save electricity. There is to observe whether there is liquid exudation, if any, proved to be bad. Finally, you can touch the hand, such as feeling the battery around the plane has proved proof bad.

Q: How to deal with waste batteries?: In addition to lead-acid batteries, all kinds of batteries are dissolved in sulfuric acid, and then by means of ion resin from the solution to extract a variety of metals, raw materials obtained in this way than the heat treatment method is pure, so the market price is higher, and the battery contains 95% of the various substances can be extracted.

Q: What battery does the van use?: The most obvious feature of lead-acid batteries is the top of the plastic cover can be unscrewed, there are ventilation holes above. These fillers are used to fill pure water, check the electrolyte and the use of exhaust gas. In theory, lead-acid batteries need to check the density of each electrolyte and the level of liquid, if there is a need to add distilled water. But with the upgrading of battery manufacturing technology, lead-acid battery development for the lead-acid maintenance-free batteries and colloidal maintenance-free batteries, lead-acid batteries do not need to add electrolyte or distilled water. Mainly the use of positive electrode to produce oxygen can be absorbed in the negative oxygen cycle, to prevent water reduction. Lead-acid water batteries are mostly used in tractors, tricycles, car start, etc., and maintenance-free lead-acid battery wider range of applications, including uninterruptible power supply, electric vehicle power, electric bicycle batteries. Lead-acid batteries according to the application needs to be divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as car to start the battery).

Q: What is the meaning of the battery above 12v65Ah?: 12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)

Q: How should the battery be well maintained?: Battery Pile The battery pile head is part of the battery connected to the vehicle. If the corrosion or poor connection occurs, the battery will work poorly. The owner can check whether there is a white powder near the pile head, which is the sign of the pile head corrosion. If the white powder is more, you can use boiling water to burn it off, and then its anti-corrosion treatment, in the pile head smear some grease or preservatives can, but should not be too much to apply, so as not to affect the use.

Q: The role of the battery?: Battery is a kind of battery, its role is to be able to save the limited power, in the right place to make 6v4ah emergency light battery. Its working principle is to convert chemical energy into electricity.

Q: How does the battery increase the voltage?: With the same battery pack in series; if the required current is relatively small, you can use DC-DC module.

Q: What is a maintenanceable battery?: Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water.

Q: How does battery activation work?: If you are talking about dry batteries, that is, to add sulfuric acid can use the battery (commonly known as water bottles), then it is because the long-term storage so that a high degree of oxidation of the negative board, plus acid will be a high temperature, Low, you can add acid in the pool after the addition of a small current for a long time to charge, you can solve. Generally with 0.05C charge to 3 times can be.

Q: Lead-acid battery how to maintain?: Along the battery cover on the exhaust hole, open the battery cover plate, some of the battery cover is APS adhesive, and some batteries are buckle connection, pay attention to open the cover when the cover plate The At this time you can see the six exhaust raft rubber cap.
