The battery has a great role in the use of the car. If it does not supply power properly, the engine and the circuit system on the car will follow. Therefore, car owners usually take good care of it, in order to avoid the engine can not start or the car suddenly stopped halfway. In fact, as long as the owner checks the engine every time, the way to spend a minute or two to maintain the battery on it.
1. Wipe the outside of the battery with a damp cloth. The dirt, oil, white powder, etc. on the panel and the pile head (ie, positive and negative poles) can easily cause the leakage dirt to be wiped clean. This often scrubs the battery, the pile head of the battery will not accumulate white etched powder, and its service life will be longer.
2. Open the battery cap and check if the water level is in the normal position. Generally there are upper and lower markings on the side of the battery for your reference. If it is found that the water level is lower than the subscript line, distilled water must be added. If you do not get distilled water, tap water can be used for emergency. Water can not be added too much, the standard is added to the middle of the upper and lower markings.
3, check the battery is charging properly. If you have a three-use electricity meter, after you start the engine, measure the voltage at the battery's two poles. It must be more than 13V to be normal. Found that the charging voltage is too low, you need to ask a professional to repair the charging system. If you do not have a three-meter, you can use the visual test: After the engine is started, turn on the battery cap to see if there are any bubbles in each cell. The normal situation is that there are constantly bubbles emerging from the water surface, and the more oil will be used, the more it will be. If you find that there is no bubbling, it is likely that the charging system is defective. Special attention should be paid to the fact that hydrogen will be generated when this test is performed. Therefore, it must not be smoked during the test to avoid the risk of explosion and fire.
The method of checking whether the battery is normal is actually very simple. The three methods mentioned in this article can be completed by ordinary owners. By detecting the problems existing in the car in time, preventing problems before they can improve the service life of the car.
Red lasers include DPSS (diode-pumped solid-state) Laser and Diode Laser. This series laser include 3 series: high power and stability, low noise and Single Longitudinal Mode Laser. Free space or fiber-coupled (SM fiber, MM fiber, homogenization fiber) output available. They are widely used in bioengineering, fluorescent substance, raman spectra and so on.
