Battery - general information, tips for maintenance
general information Mounted on the car 12-volt battery consists of six cans are placed in the positive and negative plates (lamellae) immersed in a sulfuric acid solution. The main objective is the generation of an battery current required to osuschestvleniyazapuska engine ignition / activation glow, lighting, as well as to provide on-board power and other auxiliary consumers. One hundred percent efficiency occurs when the battery ambient temperature of 27 ?� C. At -18 ?� C impact efficiency drops to 40%, and for starting the engine is required in a little over two times more energy. Starting capacity (starting current) shows the ability of the battery to start the car in cold weather. It shows the current in amperes, which gives the battery for 30 seconds at -18 ?� C without voltage drop below 7.2 V (the minimum level required for the reliable start of the engine). The higher the score, the greater the starting power of the battery. Standby power shows the time in minutes during which the battery sends a current of 25 A at 27 ?� C, ie, the time during which the battery ensures the operation of all the auxiliary equipment in the car at night and in low visibility conditions with defective generator. In winter conditions, at temperatures below -18 ?� C charging efficiency of a battery decreases due to the increase of internal resistance. For short trips in the winter the energy spent battery to start the engine, does not have time to recover, the battery starts working on the wear and gradually discharged and, in the end, fails permanently. In the summer months when long trips the engine heats up, and often happens that it is difficult to start again. In such "hot" starts sometimes not consumed less energy than in cold weather. The above is especially true for vysokokompressionnym engines with a large cylinder capacity, as well as models equipped with air conditioning. Refitting | - Disconnect the battery negative lead.
 | - Release the retaining nuts and remove the clamp.
|
- Disconnect the battery positive cable.
- Remove the battery from the pallet.
- Installation is in the reverse order.

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. The first thing to look for when buying a new battery, it is her performance. There are three characteristics.
First, the nominal output voltage, which has the same value (12) for all batteries used in cars, which virtually eliminates the chance of error.  | When buying is advisable to check the battery load fork. |
Second: Capacity, measured in ampere-hours (Ah or Ah) and is roughly determined by the supply of battery power. The choice of the value of this parameter depends on how long the battery will be 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. |
The third characteristic: the inrush current, measured in amperes (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 United 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 specified in the instruction manual of the car, under which its service life will be maximized. Purchase a battery of smaller capacity can hardly be considered a good saving money as it lasts significantly less and, in addition, may cause trouble associated with starting the engine in winter. We should not purchase the battery schrezmerno high inrush currents - this increase is associated with failure riskomvyhoda 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 most vsegoprivedet to automatically fix the problem. Recently, the country's market is full of poor quality goods and fakes. Batteries are also not an exception. There are a number of features that can be reasonably likely 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: to be the date of issue that is of particular importance for a sealed battery (maintenance-free) type. The package should certainly include product data, while the availability of instruction is not strictly necessary, due to the fact that the West batteries hardly arrive in retail sales, and their installation on the vehicle is usually carried out car specialists.
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 handled by a special anti-corrosion lubricant. Charging the battery Charging the failed battery should be done in accordance with the manufacturer's instructions charger.
