The battery is a device that converts chemical energy into electrical energy. When the engine is activated, the battery is supplied to the starter, and the starter drives the flywheel, the crankshaft rotation, thus start the engine. The automotive battery belongs to the start-up battery, which means that the starter supply rate makes the engine operation is the most important purpose.
However, when the engine is running, the battery can also convert the electrical energy of the automobile generator into chemical energy and store, when the generator is overloaded, the vehicle idle, the engine is turned off, and the power supply is supplied to the vehicle. At the same time, the battery is also equivalent to a capacitor, a voltage in the absorption circuit, protects the electronic component on the vehicle, and functions to stabilize the voltage. Battery classification automotive battery can be divided into traditional non-maintenance storage batteries and two-or-maintainable batteries.
Now there are automotive batteries on the market to avoid maintenance of battery-based. Its cost is relatively low, but due to its reduction (electrolyte) phenomenon during daily use, it is also necessary to add a supplementary liquid (distilled water) to its inside to ensure daily use. In order to facilitate the addition of distilled water, it is non-maintained to maintain the secting of the battery, which is also the most significant difference in the appearance of the battery and the maintenance battery.
However, due to the improvement of modern manufacturing technology technology, it is not necessary to maintain additional maintenance within its cycle, and its life has nothing to do with no maintenance battery without maintenance. At present, the Japanese brand is more commonly assembled with non-maintenance batteries. Since the use of conventional lead-acid battery electrolytes is much smaller, and the internal circulation of the battery is recycled, it can achieve its maintenance-free characteristics.
In addition, the maintenance-free battery has the advantages of large start current, small discharge, and small corrosion of battery pile head. At present, most models in the market are equipped with maintenance-free batteries. Battery Model Analysis: The battery model is printed at many of the many stakeholders of each battery appearance.
These models have different national standards due to their brands. In the domestic market, the method of battery models appears in accordance with national standards, Japanese industrial standards, German industrial standards, and the US Motor Vehicle Association standard, and some brands use their own name models. The following important introductions common national standards and Valta's own standards, and interpret their models.
The national GB standard 6 indicates that the battery consists of 6 monobi battery. Each single-hard battery voltage is 2V, and the rated voltage of the battery is 12V. Q means the use of the battery.
Q for the car boot battery, M is a motorcycle battery, D represents the electric vehicle battery, f represents a valve-type battery, etc. W Represents the type of battery. W is a maintenance-free battery, A is a dry-loaded battery, if there is no mark, a normal battery.
45 Indicates the rated capacity of the battery is 45ah. L Indicates the battery positive pile on the left end. The positive pole pile is in the right end to repose R.
T1 means that the battery electrode pile head is a detail, T2 is expressed as a thick pile head. Valta custom model B represents the code of battery size. Battery size code is represented by A to H, and the minimum size battery A represents, the maximum size battery is represented by H.
24 depends on the battery size group number. 45 Indicates the rated capacity of the battery to 45AHL indicates the battery positive pile at the left end. T1 indicates that the battery electrode pile head is a thin pile head.
M represents a blue standard, if h is H, a silver label, a represents the AGM start-stop battery. Date of Production: In the middle of the front side of the battery, the number of English letters is included in the English alphabetic, including the product information. 7kz16b2 in Valta.
The detailed explanation is as follows: 1, the first place is arabic number, usually 1 of 10 numbers 0123456789. 7 in the above example, indicating that the year is 2017;. According to alphabetical order, the production month of the battery is January, February, .
K in the above example is October; 3, the third is the letters, representing the manufacturer of the battery. C represents the production plant as Chongqing; Z represents the production plant Zhejiang. 4, 4th, 5th is the Arab figures, representing the production date of the battery.
In the above, 16 shows that the production day is 16; 5, 5th, and 6th, the combination of letters and numbers is a batch of the manufacturer to produce the battery; in the above example, B2 represents the production of manufacturers batch. The battery production date is generally important to see the year and month, which is the first two characters of the production date. Most of the characters behind are manufacturers, and batches.
Most of the market in the market is taken in this way. Note: 1 Of course, different brands of battery anti-counterfeiting methods are different. If there is no anti-counterfeiting code, you must see the digital number and production date on the battery plastic shell, whether it is clear.
2, the battery model is large, the price is also large. Don't buy a battery lower than the market price, most of these battery is too late, the inventory time is too long, this battery is not guaranteed, so buying a battery cannot be cheap. 3, the replacement battery model is inconsistent with the original car model, the weight will definitely be different; in addition, the weight of the original car battery must be slightly different than the same model weight on the market.
Therefore, it is possible that the weight is inconsistent with the original weight. If the new battery in the after-sales market is lighter than the old battery, it may be a counterfeit product of the scavenger.
