Q: How to repair the battery?: To the battery in accordance with the 0.1C current discharge, record the discharge time. Its discharge current multiplied by the number of hours of time, is the battery repair capacity. If the Chongqing battery capacity to reach the nominal capacity of more than 70%, the end of the repair.

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: 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?: 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: Maintenance-free battery how to detect it?: Battery pole Pole terminal has corrosive material without treatment, as long as no loose on it. If the appearance of the corrosive material, the inner surface of the terminal will also be corrosion, resulting in increased resistance, affecting the normal battery charging and discharge, it must be promptly processed.

Q: What battery does the van use?: The most obvious feature of lead-acid batteries is the top of the plastic cover can be unscrewed, there are ventilation holes above. These fillers are used to fill pure water, check the electrolyte and the use of exhaust gas. In theory, lead-acid batteries need to check the density of each electrolyte and the level of liquid, if there is a need to add distilled water. But with the upgrading of battery manufacturing technology, lead-acid battery development for the lead-acid maintenance-free batteries and colloidal maintenance-free batteries, lead-acid batteries do not need to add electrolyte or distilled water. Mainly the use of positive electrode to produce oxygen can be absorbed in the negative oxygen cycle, to prevent water reduction. Lead-acid water batteries are mostly used in tractors, tricycles, car start, etc., and maintenance-free lead-acid battery wider range of applications, including uninterruptible power supply, electric vehicle power, electric bicycle batteries. Lead-acid batteries according to the application needs to be divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as car to start the battery).

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?: Voltage 12V, current 65AH, that is the capacity of 65A. (A is the unit of current. H is the time unit)

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.
