Q:How to determine the battery is good or bad?
Instrument test: the general use of battery discharge tester, the test instrument two positive and negative clamp were holding the battery positive and negative electrodes, press the test button to observe the test instrument instructions.
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:80ah how much battery storage capacity?
Is 80AH. Understood to discharge at 80 amps for about 1 hour (but not to say that after 1 hour is finished, there is still electricity). In theory, this is your battery power.
Q:How to repair the battery?
Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
Q:What are the advantages of maintenance-free batteries?
Maintenance-free battery using lead-calcium alloy grille, the amount of water generated when charging less water evaporation is low, with the shell with a sealed structure, the release of sulfuric acid gas is also very little, so with the above advantages.
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:How is the capacity of the battery defined?
The capacity of the battery unit is AH (safety) is the product of current and time.
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 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.
Q:How to deal with waste batteries?
Laboratory recycling method: ordinary dry battery is cylindrical, the outer cylinder made of zinc, the zinc cylinder is the battery negative; tube central carbon rod for the positive; tube for the manganese dioxide, ammonium chloride and chlorination Zinc.
