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 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: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: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: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?
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 are the hazards of battery over discharge?
Excessive discharge can seriously damage the battery's electrical performance and cycle life.
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.
Our pioneering efforts have earned us 10 national patents so far. In fact, we have the second largest number of patents among listed suppliers in mainland China.We also been offering complete solutions for LiFePO4 battery pack buyers for over six years. Customers especially enjoy our battery pack, battery management system and charger solution.
