Battery - general information, tips for maintenance
Mounted on the car battery consists of six cans are placed in the positive and negative plates (lamellae) immersed in a sulfuric acid solution. The main task of the current generation of an battery is required for starting the engine, the ignition of the working mixture, lighting, as well as to provide power to other board or auxiliary power consumers. In winter conditions, at temperatures below -18 deg., Battery charging efficiency is reduced due to increase in its internal resistance. For short trips in the winter the energy spent battery to start the engine, does not have time to recover, and the battery starts to wear, gradually discharged and, in the end, fails permanently. In summer, during long trips the engine heats up, and often happens that it is difficult to start again. In such "hot" starts sometimes spent no less battery power than the freezing weather. The above is especially true for vysokokompressionnym engines with a large cylinder capacity, as well as models equipped with system K / V. For more information about the battery, refer to Section Checking battery status and care. Purchase a new battery The above indicates the importance of the correct choice of the battery within the parameters of the engine and the complete vehicle. When buying a new battery should pay attention to its performance: - Rated output voltage. It has the same value (12) for all batteries used in cars, which virtually eliminates the chance of error.
- Capacity, measured in ampere-hours (A ??? h) and roughly determined by the supply of electricity in the battery. The choice of the value of this parameter depends on how long the battery is able to provide the ability to cranking the engine, more precisely - how much can you make attempts to start the engine. The price of the battery is almost directly proportional to its capacity.
- Starting current (A), ie, current supplied to the starter when starting the engine. The amount of inrush current to the battery can be indicated in four different standards: Standard (for domestic battery), EN (the standard of Uniform Europe), SAE (the American standard) and DIN (Germany). Last, German standard, is closest to the Russian guests and most European production of batteries is put "by default", ie when the system standard is not indicated. The inrush current is, the more momentum is developing starter and the more torque it is able to transfer the engine flywheel.
Ideally, acquired replaceable battery in performance must fully comply with the requirements of the Specifications under which the battery life will be maximized. Purchase a battery of smaller capacity can hardly be considered a good saving money as it lasts significantly less and, moreover, can lead to unpleasant trouble of starting the engine in winter. Do not buy the battery with an excessively high inrush current - a passion carries a risk of failure of the starter. If a standard does not ensure proper battery to crank the engine, it would be correct to begin to replace the motor oil - that is likely to lead to the automatic elimination of problems. There are several grounds on which it is possible with a sufficient degree of probability to distinguish the original from a fake. The first, and perhaps most importantly: the battery case should be required to indicate the country of origin and the manufacturing plant, it is better if the address. Second, must indicate the date manufacturing, which is of particular importance for a sealed battery (maintenance-free) type. The package must include product data, while the availability of instruction is not strictly necessary. Third, high-quality batteries are of good appearance. The body must have smooth edges, be equipped with reliable and smooth caps, hooded protective caps pole terminals, which are often covered by a layer of a special anti-corrosion lubricant. Charging the battery Charging the failed battery should be done in accordance with the manufacturer's instructions charger.
