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: How to deal with waste batteries?: The rest of the various types of waste batteries are generally shipped to a special toxic, hazardous landfill, but this approach not only cost too much but also cause waste, because there are many useful raw materials available.

Q: What are the hazards of battery over discharge?: When the battery discharge current is large, the heat will become more obvious, there will be serious heat generated when the battery deformation, when the concentration of lead sulfate is particularly large, will form a larger crystal particles, that lead to the battery Internal irreversible sulfation.

Q: Maintenance-free battery how to detect it?: Check the height of the electrolyte at least once a month. There is no mark line of the battery, the electrolyte added to the plate 10-15mm can be higher; there are two red line of the battery, the electrolyte can not exceed the red line above.

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 kind of battery is divided into?: Ordinary battery: ordinary battery plate is composed of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. Its main advantage is the voltage stability, the price is cheap.

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: Battery 200ah / 104 what does that mean?: 2V battery capacity (from 200AH-3000AH have) long design, good stability, the price is also expensive; 12V battery capacity is generally the largest 250AH, design life as 2V, price economy, high current discharge better.

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?: After 5 hours of repair, the excess electrolyte is sucked out with a straw, and if the electrolyte is sucked out into black, it indicates that the battery is severely grounded and that the battery is difficult to repair.
