Battery is also an essential part of the car, which can be divided into traditional lead-acid batteries and maintenance-free batteries. The lead-acid battery is composed of a positive and negative plate, a partition, a housing, an electrolyte, and a wiring pile, which is the use of the electrode plate active substance and the negative plate active material in the electrolyte (dilute sulfate). Take it, the grid frame of the plate is made of lead binder alloy.
Moreover, it has advantages such as the traditional battery, which does not need to add any liquid, the long supply of the wiring pile, and the long battery storage time. Therefore, in terms of voltage testing of the battery, it is not negligible. Let's take a look at the steps to check the battery voltage.
When the battery voltage is tested, the vehicle should be at least in a stationary state for 2 hours, and it is not started within 2 hours, not loading, no unloading. It is important to note the closed ignition switch when measuring the broken circuit voltage between the battery terminals with the battery tester. If the test is tested is equal to or greater than 12.
5V, this is to indicate that the battery is normal. But if the voltage is less than 12.5V, then the owner is looking for the original.
It is proposed that it should be noted that the battery voltage cannot be measured with a digital multimeter or a pointer multimeter, as this measurement is not loaded, the meter display value is not necessarily the actual voltage of the battery in the measurement circuit. Result in incorrect measurement. .
