Car battery is one of the necessary parts of the vehicle, but many car owners may encounter the problem of battery power loss during use. So, how to check whether the car battery is losing power in the process of use? What are the techniques in life that can extend the service life of the car battery? How to check whether the car battery power loss?
1, the most common situation is that it is difficult to start, and it takes many attempts to start the vehicle; another situation is that after starting, the dashboard appears to be garbled; for high-grade models, if the battery is in deficit, the dashboard will display a warning sign!
2, the battery also has a quantitative detection method, that is, check the starting voltage. When the starting voltage is below 9 volts, it is recommended to replace the battery. No-load voltage should be between 12-13 volts and not be used as a basis for replacement. When the starting voltage is below 9 volts, some owners may be reluctant to replace it, and it may even last two or three months, but it may not start at any time.
Keeping an eye out can still detect problems. For example, honking the horn (snail horn) while parked becomes raspy and weak, starting is a bit of a drag, and idle speed drops immediately after starting with the headlights on (increased load on the generator). As for when it completely hangs up and how long it will last, it's really hard to say, the structure of the battery determines that its death process can be sudden, when the internal pole plates are twisted to a certain degree, it will be a problem, even if it's fine in the morning, it may not start at noon. Especially batteries that have been in deficit for a long time and can't be charged effectively can easily hang up prematurely.
Tips to extend the life of the car battery
1, the battery manufacturer stipulates that the life of two years, but different models of the use of three to five years is not a problem, which is related to the owner's habits of use, such as idling or even stalling often use the stereo, as well as the number of electronic devices in the vehicle. It also has a lot to do with the fact that the battery is front-loaded in the cabin and rear-loaded in the trunk, and the life expectancy can be more than twice as long!
2, pay attention not to let the air conditioning with the vehicle start automatically start, because this will lead to the vehicle instant power load is too high, long-term wear and tear on the car battery. Therefore, each time before you reach your destination, you should turn off the A/C button and let the cold air blow for a few minutes to ensure that the inside of the air conditioning system is dry and to reduce the growth of bacteria, then turn off the air conditioning and turn off the engine. Turn off all electrical power before leaving the vehicle.
3, If you have a long-term travel plan, you need to start the vehicle and run it for 20 minutes every 15 days or so. If the vehicle is stored for more than 15 days, disconnect the negative battery cable.
4, for example, those who have installed a high-power stereo owners, a car on the stereo to drive away the volume of the square dance aunt ~ ~ ~ so play without changing the high-power generator, the battery half a year to hang a very normal.
5, there are some friends who work very close to the 10-minute walk, walking is also very easy, but the fear of damage to the vehicle, every day to drive back to the unit. Need to know, start the need for high-current discharge, each time such a discharge run 10 minutes simply can not charge back, long-term use, will also lead to the battery hang up a year and a half.
