- 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 technical parameters of the battery?
- Usually the capacity of the power supply is expressed by kV · A or kW. However, as a power supply VRLA battery, the use of security (A · h) that its capacity is more accurate.
- Q: How to determine the battery is good or bad?
- General side maintenance has an observation hole if it is green to prove that the battery is normal if it is black to prove that the battery does not save electricity. There is to observe whether there is liquid exudation, if any, proved to be bad. Finally, you can touch the hand, such as feeling the battery around the plane has proved proof bad.
- Q: What are the hazards of battery over discharge?
- The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.
- Q: How should the battery be well maintained?
- Electrolyte density This is to evaluate whether the battery charge is normal, whether the aging of the important parameters, the use of density meter or electrolyte density tester can be measured. If the electrolyte density is too small, you need to charge. And the electrolyte concentration is too thick or too thin to a certain extent, it means that such as the occurrence of plate vulcanization, short circuit or overcharge phenomenon, this time on the need for maintenance.
- Q: 80ah how much battery storage capacity?
- The size of the battery storage power refers to the battery capacity. Battery capacity is generally calculated in AH (safety). You 80Ah battery capacity is 80Ah, meaning that if you discharge current to 80A, you can put an hour.
- Q: The role of the battery?
- Battery is widely used, can be used for ups, electric cars, scooters, cars, wind energy solar systems, security, and so on.
- 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?
- Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water.
- Q: How does battery activation work?
- If the battery is charged, because the battery discharge itself, the active substance to activate, not add acid, but should be added pure water (no minerals and impurities in the water) is best steaming water, and now you Since the addition, you can use water to wash several times, and then use 1C current charge to 2.3 times. Then discharge, so repeated several times, will be better. So that you can remove the vulcanization.
