Method for Correct Inspection of Battery Voltage

Battery is an indispensable part of the car, which can be divided into traditional lead-acid batteries and maintenance-free batteries. Lead acid batteries are composed of positive and negative plates, partitions, shells, electrolytes, and junction piles. The chemical reaction of discharge depends on the positive plate active material and the negative plate active material in the electrolyte(dilute sulfuric acid solution). The action is carried out. The grid of the polar plate is made of lead-antimony alloy. And compared with traditional batteries, it has the advantages of not adding any liquids, connecting piles, and long power storage time. Therefore, the voltage detection of the battery can not be ignored.

Let's take a look at the steps to check the battery voltage in turn.

When the battery voltage is tested, the vehicle should be at least in a stationary state for 2 hours. Within 2 hours, it will not start, load, or unload.

When using the battery tester to measure the disconnect voltage between the battery terminals, note that the ignition switch is turned off. If the detected voltage is equal to or greater than 12.5 V, this indicates that the battery is normal. But if the voltage is below 12.5 V, then the owner will have to find out why.

It is recommended that when testing, it should be noted that the battery voltage can not be measured using a digital multimeter or a pointer multimeter, because this measurement method does not have a load in the measurement circuit, and when the side amount is measured, the instrument display value is not necessarily the actual voltage of the battery., Which could lead to inaccurate measurements.

The above is the small editing of the battery voltage when the method, it is hoped that the above is useful to the owner. In fact, it is useful to regularly check the voltage of the car's battery, so that you can always understand the safety of the car.
