e. E-mobility battery for E-scooter, E-bus, E golf cart etc.(Rank Top 3 in China).

f. 48V 50A/100AH/150AH/200AH LFP Battery for Telecom-towers.

Q: What is the capacity of production?

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: What are the technical parameters of the battery?: The main performance parameters of the battery are the following: model; voltage; battery capacity; battery type, such as lead-acid batteries, alkaline batteries, lithium batteries, solar cells, fuel cells.

Q: How to deal with waste batteries?: The old battery is ground and then sent to the furnace for heating, then the volatile mercury can be extracted, the temperature is higher when the zinc is also evaporated, it is also precious metals. Iron and manganese fusion after the steel to become the required ferromanganese alloy.

Q: What are the hazards of battery over discharge?: The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.

Q: What battery does the van use?: The battery is mainly composed of tube positive plate, negative plate, electrolyte, separator, battery compartment, battery cover, pole, injection liquid cover and so on. The electrode of the exhaust type battery is made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is the voltage stability, the price is cheap; the disadvantage is lower than the energy (that is, per kilogram of battery storage power), short life and routine maintenance frequently. Old ordinary battery life of about 2 years, and the need to regularly check the height of the electrolyte and add distilled water. However, with the development of science and technology, lead-acid battery life becomes longer and maintenance is also more simple.

Q: What are the advantages of maintenance-free batteries?: Maintenance-free battery using lead-calcium alloy grille, the amount of water generated when charging less water evaporation is low, with the shell with a sealed structure, the release of sulfuric acid gas is also very little, so with the above advantages.

Q: What is the meaning of the battery above 12v65Ah?: 12V represents the rated voltage. 65Ah indicates that the battery capacity (ie 1 ampere current can be used for 65 hours).

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: Battery 200ah / 104 what does that mean?: This should be refers to 2V200AH battery 104, power with the 220V.

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.
