car battery is an important component, its function is to provide electric start, start the engine at low speed running, the ignition system of the engine and other electrical supplies. When the operating speed of the engine, enough power generator, the battery can store excess energy. Unfortunately, it is generally ignored by most people. I do not know the correct battery must be maintained in order to maintain full power, is an important part of vehicle maintenance. The following will introduce the car battery conservation and common sense, to help you better understand the use and maintenance of the battery to extend battery life.
Electrochemical device for power. Lead-acid battery positive and negative plates, separators, casing, electrolyte, etc. electrical coupling, trailer and release of the chemical reaction is to build on the positive plate active material (lead dioxide PbO2) and material the negative plate active (sponge of pure lead Pb) in the electrolyte (sulfuric acid composition of H2SO4 and H2O water) in the role. A standard battery 12V lead-acid contains six modules, each of approximately 2V supply of energy produced (one for each power supply has positive and negative column: column with inscription positive sign “+” brown dark column when a negative “-” sign, light gray).
Traditional batteries will be held during the electrolyte is in decline, because the gate electrode holder, dell-inspiron-1521.htm”>battery traditional lead-antimony alloy, antimony will pollute the negative plate of pure lead sponge, weakened after the battery is fully charged within cons electromotive force, causing the decomposition of water on a large number of oxygen and hydrogen have been escaping the positive plate and negative electrolytic reduction.
Maintenance (maintenance free) batteries into the design principles of the battery and the traditions of consensus on the use of thicker material plate, important difference is that part of the plate with a lead-calcium alloy. In the electrolysis process, reduces the current congestion, reduce the rate of vaporization of liquid, which reduces the loss of electrolyte, the relative lifespan of the battery.
Discharge and charge
Discharge (Discharge) process plates of lead dioxide (positive), the sponge lead (negative) and the electrolyte of sulfuric acid discharge chemical reaction to produce lead sulfate (PbSO4) and water (H2O ), the positive and negative plates the difference between reduced. Because the voltage of the battery depends on the materials of electrodes and electrolyte concentration, the reaction of discharge, loss of cell energy. (Charge) and discharge process in the opposite. Under the action of the current generator, the lead sulfate in water and lead dioxide (positive), the sponge lead (negative) and sulfuric acid, plates, electrolyte concentration recovery, increase the power of the battery. vgp-bps9
Caution
1 to start the car every time you start the time must not exceed 3 to 5 seconds, repeat interval of at least 10 seconds.
2, often short drive car, open the station opened, will lead to the battery charge is insufficient long-term status, short life. In highway driving at a steady speed of 20? 30 minutes, may give enough time to recharge the battery.
3, daily driving, before leaving the car, make sure that all lights and other electrical appliances (such as radios, CD) has been closed. Because it can drain your battery.
4, if the battery runs out, ask for light (relaunch, also known as taking the line) to immediately initiate a constant speed (such as highway speed) drive at least 20? 30 minutes to fully charge the battery.
5, in the case of the battery is completely discharged, ask the fire may be unable to help you launch vehicle. At this point, you must use a special battery charger to trickle charge.
6, if the cars do not stand a long, should full charge of the vehicle. At the same time every month to start the car, their average operating speed of about 20 minutes. Otherwise, place too long, it will be difficult to start.
7, the battery life around. Use more than four years, the proposed replacement.
