　　How to maintain and disassemble a car battery?

　　Remember to turn off the lights and air conditioner before parking to reduce battery consumption, start the generator regularly, wipe the dust and oil on the electrode with a damp cloth, unscrew the fixing nut, and take out the battery. Next, I will introduce the details to you.

　　1. How to maintain car batteries

　　1. Before parking, turn off the lights and air conditioner.

　　Some older models do not support the automatic power-off function after the engine is turned off, so you need to manually turn off the lights and interior reading lights before turning off the engine. If you need to find something in the car or need lighting, you can use your mobile phone or flashlight for lighting, so as not to turn on the reading light and forget to turn it off, causing the battery to lose power.

　　2. The car also needs to be driven around frequently.

　　Even if all the electrical systems in the car are turned off, the battery power may be exhausted after the car is parked for a long time. Therefore, even if the car is left idle at home for a long time, the engine must be started regularly. Fortunately, just walking on the road for more than 20 minutes can ensure that the battery has enough time to charge.

　　3. Wipe it for better health

　　Open the hood regularly and wipe the positive and negative terminals of the battery with a damp cloth (that is, the two exposed silver cylinders connected to a black wire and inserted on the surface of the battery). Regularly wipe the dust, oil, and white powder covering the electrode head with a damp cloth. This not only plays a cleaning role, but also effectively reduces the accumulation of white acid-etched powder and protects the battery.

　　4. Before turning off the engine, close the windows

　　The car's windows and sunroof switches are powered by batteries, so it is best to close all windows before turning off the engine instead of closing them after turning off the engine. You can even close the windows by pressing and holding the lock button after leaving the car.

　　2. How to disassemble the car battery

　　1. Loosen the nut of the negative electrode connector: Open the two fixing buttons of the insulation cotton, and you can see the two red and black insulation covers on the positive and negative electrode connectors. Open the insulation cover and you can see the locking nut;

　　2. Disassemble the negative electrode connector: Use a wrench or hex socket to unscrew the fastening nut of the negative electrode, then use a flat-blade screwdriver to slowly pry open the fastening block, and then pull out the negative electrode connector;

　　3. Disassemble the positive connector: Use the same method to disassemble the positive connector;

　　4. Disassemble the locking strap: Unscrew the nut used to fix the battery's locking strap, loosen the locking strap, and then take out the battery.

　　5. When installing a new battery, just follow the reverse steps. However, it should be noted that the order of installing the positive and negative connectors is "positive first, then negative", which is opposite to that of disassembly. The principle is the same, both to prevent the risk of short circuit and ensure safety.
