The annual National Day holiday is coming again. There is only one National Day holiday in a year, and the coming of the holiday is sure to go out for a look. In order to ensure the safety of travel during the holiday. I made all preparations in advance a few days before the National Day. In addition to arranging things to travel, it is more important to check the condition of the car. The inspection was terrible and it was found that the battery had run out of power seriously. You can’t delay your holiday trip for this reason. Fortunately, I had experience in this area, and my hands-on ability was quite good, so I took care of it myself. Next, I will share the process with you in detail.
The first step is to open the hood. Find the battery and break the retaining pin on the left side of the battery box to the left.
Hold the front end of the battery cap in your hand, break it out and lift it up again.
At this time, the battery is completely exposed.
Take out the multimeter first. Switch the multimeter to DC voltage range, red and black pen, respectively, on the positive and negative poles of the battery, do not ignite. Directly measure the battery voltage at this time. I measured it to be 11.81V at this time. Less than 11.8 volts is a loss of power. It seems that the current voltage of my battery is in the lower limit. If you don’t recharge in time, there may be a serious power loss.
There are two ways to charge: one is to start the car directly and then run more than 60 or 70 kilometers. The purpose of this is to charge the battery. Although this method can charge the battery, it is difficult to grasp the “scale” of charging. It is possible that the charging voltage is still lower than the standard voltage, so the battery will continue to lose power, and the effect is relatively poor. Another method is to remove the battery and use a lead-acid battery charger for charging and maintenance, which works best. In order to ensure that the charging can achieve good results, I intend to remove it for charging and maintenance.
The next step is to use this three-end sleeve.
Use the 10mm sleeve of the three-end sleeve to remove the positive and negative screws of the battery. Put the sleeve on the screw and loosen it counterclockwise.
After loosening the screw, lift the positive and negative connection of the battery up directly, and the positive and negative connection of the battery can be removed.
There is also a fixed clip on the lower left side of the battery box. You have to loosen the clamp before you can take out the battery.
Use an adjustable wrench to loosen the retaining clip counterclockwise.
The fixing clip has been removed.
Insert your hands into the left and right side of the battery, and then lift it up to take out the battery.
The battery is out.
Next, let’s take a look at the current state of the battery.
This one is the eye of the battery.
The marked electric eye is in the normal state and the scrapped state of serious power loss. If it is normal, it should be black; if the battery is seriously out of power, it will turn yellow when it reaches the level of scrapping. Fortunately, my electric eye is still black.
The capacity of the battery is larger and more durable, and I also choose the better capacity of 60ah.
The next step is to use this 12-volt lead-acid battery charger to charge it.
This charging instruction is the opposite of our common charging instructions. This is a green indicator indicating that it is charging; the red indicator is full.
The battery end of the charger has red and black chucks.
The terminal of the battery is cylindrical, so it is not convenient to install the chuck. So two round hoops should be installed here.
Install two round hoops with a word screwdriver.
First put the red crocodile clip on the positive hoop on the right.
Then clip the black crocodile clip on the negative band on the left.
In this way, the wiring on the side of the battery is completed.
And then plug it in. Don’t reverse this order. If it is reversed, plug in the power first. if the positive and negative crocodile clips are accidentally put together, there will be a short circuit.
At this time, the charging indicator is green, indicating that charging is in progress.
After nearly 24 hours of charging, the indicator light of the charger has now turned red, indicating that the battery is fully charged.
It also connects to tens of thousands of meters. Check the current battery voltage and show 13.04V. It has reached the standard voltage of the battery before starting. Such a battery which is nearly out of power has been repaired.
Finally, a comparison table for judging the voltage value of the battery is attached. You can refer to this comparison table to see whether the current voltage value of the battery is in a standard state, or on the verge of losing power.
