Q:How should the battery be well maintained?
So the proposed owners if the vehicle long-term stop, but also 2 to 3 months for the battery for a charge.
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 repair the battery?
Maintain the battery before, first of all to clean up the battery appearance of the dust, remove the terminal above the stain and corrosion.
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 battery does the van use?
The battery is mainly composed of tube positive plate, negative plate, electrolyte, separator, battery compartment, battery cover, pole, injection liquid cover and so on. The electrode of the exhaust type battery is made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is the voltage stability, the price is cheap; the disadvantage is lower than the energy (that is, per kilogram of battery storage power), short life and routine maintenance frequently. Old ordinary battery life of about 2 years, and the need to regularly check the height of the electrolyte and add distilled water. However, with the development of science and technology, lead-acid battery life becomes longer and maintenance is also more simple.
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 does battery activation work?
If you are talking about dry batteries, that is, to add sulfuric acid can use the battery (commonly known as water bottles), then it is because the long-term storage so that a high degree of oxidation of the negative board, plus acid will be a high temperature, Low, you can add acid in the pool after the addition of a small current for a long time to charge, you can solve. Generally with 0.05C charge to 3 times can be.
Q:Lead-acid battery how to maintain?
Along the battery cover on the exhaust hole, open the battery cover plate, some of the battery cover is APS adhesive, and some batteries are buckle connection, pay attention to open the cover when the cover plate The At this time you can see the six exhaust raft rubber cap.
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: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.
