FAQ

CFE Lithium-ion Battery

Q: What kind of battery you can provide?

A: a.12.8V-25.6V 30Ah/40Ah/50Ah/100Ah//200Ah LFP battery for replacement of Lead-acid/Gel battery.

b. 51.2V 50Ah/100Ah LFP battery module for residential energy storage with cube (10,15,20 kwh).

c. Solar hybrid inverters with power 4,5,6,8,10,12kw, solar off grid inverter 3,5 kw.

d. Inverter & Battery ALL IN ONE, with capacity 5,10,15,20 kwh.

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 is the capacity of the battery defined?: 100AH capacity of the battery, fully charged after the 100A current discharge can be an hour to put the power finished. 50A current is 2 hours put away! 20A is 5 hours! Of course this is the theoretical value, in fact it is impossible to have a constant current discharge.

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 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: 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: 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: 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: 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?: This is relative to a maintenance-free battery. Maintenance of the battery needs to be supplemented with electrolyte to ensure work, while maintenance-free is not required.

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

Q: Lead-acid battery how to maintain?: After passing the test, cover the exhaust cutting, pay attention to restore the filler, cover the battery cover, if the cover is glued, then glue bonding.
