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 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 is the difference between a maintenance-free battery and a conventional battery?: Lead-acid battery is composed of positive and negative plates, partitions, shell, electrolyte and wiring pile head and other components, the discharge of the chemical reaction is to rely on positive electrode active substances (lead dioxide and lead) and negative plate active substances (sponge Pure lead) in the electrolyte (dilute sulfuric acid solution) under the action, which plate grid, the traditional battery lead and antimony alloy manufacturing, maintenance-free battery is made of lead calcium alloy, the former with antimony, the latter with calcium, This is the fundamental difference between the two points.

Q: How to determine the battery is good or bad?: Observe the battery electrolyte is turbid, turbidity that the battery positive plate softening. Observe the bottom of the battery whether there is sediment, if the plate off the battery capacity has been inadequate. Hand hit the battery two electrode piles If you hear an empty voice that pole pile and plate break. With a thick wire short-circuit positive and negative pile observation of the battery filling holes, such as the discovery of a bubble appears that the interval has been damaged.

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?: Excessive discharge can seriously damage the battery's electrical performance and cycle life.

Q: What are the advantages of maintenance-free batteries?: The advantage of a maintenance-free battery is that the service life is twice as long as the dry battery! And in the use of the process without maintenance! The voltage is also relatively stable.

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: What kind of battery is divided into?: At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.

Q: How does the battery increase the voltage?: You can use the same battery in series, with 5 12v battery in series becomes 60v, if you need the current is relatively small, you can use DC-DC module to 12v voltage rise to 60v.
