Some people who often need to travel by car, or outdoors, usually encounter the situation that the automobile battery feeds can not start normally. In order to start the automobile normally, emergency starting power supply is usually equipped. However, the use condition is to determine that the reason why the automobile can not start is the automobile battery. Although it is useful in the case of automobile failure, there are also some precautions in use, whether it is traditional lead-acid batteries with large power or current popular lithium polymer batteries. If the method is not correct, it may be more dangerous.
There are two kinds of emergency starting power supply for automobiles:
1. Lead-acid batteries: Emergency start-up power supply for automobiles such as lead-acid batteries is more traditional. Maintenance-free lead-acid batteries are adopted, which have larger mass and volume, larger capacity and start-up current, and longer service life. This kind of start-up power supply is usually equipped with an inflatable pump. It also has the functions of current, overload, overcharge and reverse connection indication protection. It can supply power to various electronic products and some household appliances, and some even have the functions of inverters.
2. Lithium polymer batteries: Lithium polymer batteries are relatively new to lead-acid batteries in emergency starting power supply for automobiles. Their characteristics are light weight, compact size, and can be mastered by one hand. They are important types of convenient emergency starting power supply for automobiles used by many car owners. Such products are generally not equipped with inflatable pumps, with overcharge shut-off protection function. At present, the automobile emergency start power supply products are more humane, not only limited to the start of the car, but also equipped with lighting functions, as well as power supply for various electronic products; the lighting lights of these products generally have the function of explosion or SOS remote LED rescue signal lamp, which will make the traffic rescue safer.
Attention should be paid to emergency start-up power supply for automobiles:
I. Attention to Voltage
When choosing emergency starting power supply for automobiles, owners need to know their own car voltage to buy a suitable emergency starting power supply for automobiles. If the voltage does not match, too high will cause damage to automobile batteries, and even dangerous; if insufficient, it will be difficult to start successfully and waste the power in the emergency power supply of automobiles in vain.
2. Maintaining adequate electricity
Emergency starting power supply for automobiles is widely used. In addition to providing high current for automobiles to start in a short time, it can also charge various digital products. So it is also a kind of mobile power supply. If it is not used for a long time, it will also have the problem of power reduction. So when it is not used in normal times, it should be properly charged so that it can keep full power for a long time, be convenient for next use, and also prolong the service life of emergency starting power supply for automobiles.
3. Attention to the Number of Startups
Before using emergency start power supply to start a vehicle, it is necessary to know the number of start times of emergency start power supply. Sometimes starting a car may not succeed at one time, but the emergency starting power supply is limited, even if starting fails, it will consume electricity. Generally, lithium polymer power supply can be used 5-10 times in full state, while lead acid power supply can be used more often because of its large capacity, mostly about 30 times, so it is better to have a comprehensive inspection if the car has not been started after several attempts. Check if the car really can't start because of feeding.
IV. After-sales Service
When purchasing automobile emergency start-up power supply, besides quality assurance, we should also pay attention to after-sales service, so as to facilitate the problems encountered in the future use process to be solved in time, which is much stronger than our own exploration, and after-sales improvement is always good.
It is suggested that when choosing emergency start-up power supply for automobiles, we must choose brand manufacturers with large brands, quality assurance and perfect after-sales service. Only in this way can the power supply be safer and safer than anything else.
