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?: Battery capacity is defined as ∫ t0tdt, theoretically t can be infinite, but in fact when the battery discharge is lower than the termination voltage continues to discharge, which may damage the battery, so t value is limited, the battery industry, in hours (h) Battery sustainable discharge time, feel the C24, C20, C10, C8, C3, C1 and other nominal capacity value.

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

Q:What is the difference between a maintenance-free battery and a conventional battery?: Different materials will produce a different phenomenon: the traditional battery in the course of the use of the phenomenon of liquid reduction occurs, because the antimony on the grid will pollute the sponge on the negative plate of pure lead, weakened after the full charge of the battery Electromotive force, resulting in excessive decomposition of water, a large number of oxygen and hydrogen, respectively, from the positive and negative plates to escape, so that the electrolyte reduced. With calcium instead of antimony, you can change the fully charged battery back electromotive force, reduce the overcharge current, liquid gasification rate decreases, thereby reducing the loss of electrolyte.

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:How to repair the battery?: Pry open the adhesive or heat-sealed battery cover, reveal the maintenance-free battery rubber exhaust valve, carefully remove the exhaust valve, save, observe the battery internal situation. Add 0.1% to 0.5% of the electrolyte to the battery, just to the battery above the flow of electrolyte. At the same time, check whether the black impurities, if there are obvious black turbid impurities, indicating that the battery plate has been significantly softened, the possibility of battery repair is relatively small. If there is no black muddy impurities, need to wait 4 hours later, the water fully into the battery. If it is only because the deactivation time is long and cause the battery capacity to decline, do not need to carry out this step operation, should go directly to step 3 pre-charge.

Q:The role of the battery?: It filled with lead plate filled with sponge lead as a negative electrode, filled with lead dioxide lead dioxide as a positive electrode, and with 22 to 28% dilute sulfuric acid as electrolyte. In the charge, the electrical energy into chemical energy, the discharge of chemical energy and into electrical energy.

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?: 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:How is the capacity of the battery defined?: The capacity of the battery unit is AH (safety) is the product of current and time.

Q:How should the battery be well maintained?: Voltage check the state of the battery standard voltage should be maintained between 12.2 ~ 12.7V. If the voltage is too low should be charged, the charge should be kept small charge for a long time. Battery charging need to use a professional charger, the owner will not try to charge their own, the owner can only keep the engine running on the battery can be charged. If the battery aging should be replaced.
