In the process of using the sealed 12v battery, if it can still be used, I believe that many friends will not consider replacing a new sealed 12v battery. When installing the battery, we should pay attention to some small details during the installation process. The details are very important. Now the editor of the manufacturer will tell you the six skills of the sealed 12v battery during the installation process: the big reason is that we don’t know when it is more appropriate to replace the sealed 12v battery. As consumers, how do we judge the battery that needs to be replaced during use? Let's take a look at it with the editor.

　　When we use the sealed 12v battery for a long time, it will age and cause the capacity to drop and cannot meet the needs of customers. At this time, we recommend that customers replace the sealed 12v battery with a new one. The lead-acid sealed 12v battery generally slows down after a period of use. Slow capacity decline, according to the quality of the sealed 12v battery, plus whether the subsequent maintenance is proper, after a certain period of time, the sealed 12v battery will not meet the needs of users due to various reasons, and we need to replace the sealed 12v battery.

　　But how do we judge whether the sealed 12v battery is unusable, and replace our sealed 12v battery in time? In fact, it is very simple. The lead-acid sealed 12v battery can be used to determine whether the sealed 12v battery needs to be replaced by its internal resistance. The internal resistance of the lead-acid sealed 12v battery refers to the resistance experienced by the current flowing through the lead-acid sealed 12v battery when the lead-acid sealed 12v battery is working. It is generally divided into AC internal resistance and DC internal resistance. The resistance is very small. When the DC internal resistance is measured, the polarized internal resistance is generated due to the polarization of the electrode capacity, so its true value cannot be measured. The AC internal resistance can avoid the influence of the polarized internal resistance and obtain the true internal value.

　　Tip one, buy a battery with the same model and parameters as the old battery.

　　The second technique is to measure the voltage in the sealed 12v battery circuit with a device dedicated to measuring the battery voltage to confirm whether the voltage is normal.

　　Tip 3: After the purchase is completed, install it, and judge the working condition of the battery after installation, and disconnect the air switch before that.

　　Tip four, use the sealed 12v battery cabinet air switch, confess that the sealed 12v battery alarm is eliminated and normal working conditions are restored.

　　Tip 5, disconnect the sealed 12v battery string connection section by section, disassemble the old sealed 12v battery, and device the new sealed 12v battery, and restore the sealed 12v battery string connection section by section.

　　Tip Six: After the homework, do a quality inspection and notify the skill to resume normal operation.
