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:Battery 200ah / 104 what does that mean?
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.
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 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: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: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.
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 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:Maintenance-free battery how to detect it?
When using a maintenance-free battery, it is easy to think that maintenance-free is the idea that no maintenance is required. Maintenance-free Although maintenance costs and times can be reduced, but for the appearance of the clean-up is essential, so that "maintenance-free" more point to the battery inside.
Q:What kind of battery is divided into?
At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.
