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: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: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: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.

Q:How does the battery increase the voltage?: The so-called battery is the storage of chemical energy, if necessary, the release of electrical energy of an electrical chemical equipment.

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:What are the advantages of maintenance-free batteries?: Maintenance-free battery because of its normal charging voltage, the electrolyte only produce a small amount of gas, so throughout the use of the need for the addition of distilled water, in the normal charging system, do not need to remove the charge from the removal. But in the maintenance of the proportion of its electrolyte should be checked.

Q:How is the capacity of the battery defined?: General circuit has a battery protection circuit, once the battery voltage is less than 10.8V will automatically cut off the electricity to prevent the battery because of over-discharge and damage. (Nominal value of 12V battery internal six cell grid) with the battery discharge current multiplied by the discharge time to express how much energy the battery can store, is a very image of a measure. The greater the value of the battery, indicating that the battery can store more energy. But does not mean that the battery can use such a large current discharge.

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:Battery 200ah / 104 what does that mean?: This should be refers to 2V200AH battery 104, power with the 220V. Lead-acid battery nominal voltage is 2V / (each or monomer), but in fact will be higher than 2V, so the actual use and charging equipment for the matching will use 104, also useful 103, also useful 108 Only.
