The battery of the car loses power, which will cause the battery to be vulcanized. If a serious power loss occurs, the battery may even be scrapped. Battery power loss is the deep discharge of the battery, the voltage is lower than 10.50V, sulfuric acid and lead plate generate lead (II) sulfate, if not charged in time, lead (II) sulfate will form crystallization, crystallization time is long, recharging will not decompose, which is called sulfation of battery.
After the car battery loses power, it should be charged with battery charger immediately. If it cannot be charged with ordinary battery charger, it is necessary to use rehabilitation instrument high resistance repair to increase the voltage to more than 10V before rushing in.
How do I know if the battery is out of power?
You can still feel it with a little attention. For example, when you are not in the car, press the horn (snail horn) and the sound is hoarse and weak, and the start is a little muddy. After the start, the idle speed of the headlight is immediately pulled low (the generator load is plus-sized). As for when to hang completely and how long it can last, this is really hard to say. The structure of the battery determines that its death process will be very sudden, and the polar plate inside will twist to a certain extent, if you say no, it won't work. I'm afraid that I'll be fine in the morning and I won't be able to catch the car at any time at noon. In particular, if you lose electricity for a long time and do not get an effective charging battery, it is easy to hang up the polar plate in advance.
Reasonable Use to prolong battery life
The life of battery manufacturers is two years, but it is not a big problem to use 3 or 4 years for different models, which is related to the usage habits of car owners. For example, when idling or even flameout, they often listen to the stereo, it has much to do with the number of electronic equipment of the car, and it has much to do with the front of the battery in the cabin and the rear in the trunk. The service life may differ by more than twice!
If you have a long-term travel plan, you need to start the car every 15 days or so for 20 minutes. If the vehicle is stored for more than 15 days, disconnect the negative connection of the battery.
There are also some friends who are very close to work, 10 minutes away, walking is also very easy, that is, afraid of the car being broken, driving back to the unit every day, you need to know that the start requires high current discharge, every time the discharge runs for 10 minutes, it can't be charged back. If you use it for a long time, you have to hang up for a year and a half.
