Solutions to common battery failures

Solve common battery failures. If the battery has problems, car owners don’t need to worry. Common problems include reduced charge, self-discharge, recharging, etc. The troubleshooting methods can be described as: 1. Have enough power or use an excellent battery, 1~2 After days, there will be no power and the headlights will not light up. Press the electric horn to reduce the sound or even a small ring, which can be regarded as the battery discharge. There are two important reasons: one is that too much foreign matter accumulates at the bottom of the battery box, forming a short circuit inside the battery; second, the battery shell is too dirty or the electrolyte is too much in the turbulent flow, forming a short circuit on the cap and pile head. Therefore, first check whether the appearance of the battery is clean, and the electrolyte overflows too much to form a conductive layer, and then check whether there is a bad contact between the pile head and the wire, or whether the iron is bad. The diagnosis method is: disconnect the power switch and remove the negative battery connection. It will scratch the pole on the pole. If there is a spark at this time and the battery is short-circuited, it should be opened for maintenance. 2. The battery charging is not in the normal operation of the engine and transmission. Although the battery has been charged for a long time, the voltage rises slowly. (1) The important reasons for the failure of the battery to charge are: (1) Loose and rusty terminals of the charging cable lead to poor contact, which increases the resistance and reduces the current intensity; (2) Rectifier failure or diode short-circuit; (3) After the battery plate is vulcanized, it has a layer of white lead sulfate particles with poor conductivity. (4) Due to the use of large current to allow the battery to be energized or large current to discharge the battery, or the electrolyte density is too large and the liquid level is insufficient, the battery panel is damaged. Knowing these few simple common sense, you can let the car owner have some knowledge about the battery problem, and the problem will be solved with fear, and it is no longer an annoyance of the battery.
