Operation method of Battery replacementStep 1: pick up the key to get off the bus Step 2: remove the old battery in negative and then positive order Step 3: compare the old and new batteries and confirm that the performance of the batteries is consistent. Step 4: clean the battery pole pile and two clamps Step 5: install and fix the battery Step 6: connect the positive and negative clamps of the battery (pay attention to positive and then negative) and fasten to the corresponding torque Note: when replacing, we must avoid short circuit; when replacing some high-grade car batteries, due to the battery can not be easily cut off, it is necessary to use OBDII for vehicle power supply, and then battery power-off operation

Battery status inspection through the sight flow glass (for batteries with sight flow)Open the battery protection pad (if any), visually check the battery surface is clean, whether there is no liquid outflow. Visual Check Battery Status Indicator: Green: Battery power is sufficient Black: Low charge or no electricity Colorless or yellow: electrolyte reaches critical state- tire

Inspection of positive and negative clamps in batteriesShake the positive and negative clip with your hand to judge whether it is loose or not; if the positive clip is loose, disconnect the negative clip of the battery and do a good job of isolation. The positive electrode of battery is fastened 5-8N ▪ m by torque wrench, and then the negative electrode of battery is installed and fastened 5-8N ▪ m.

Voltage inspection of batteryWhen the static voltage of the car battery is in the OFF position, open the hood and lock the car. Waiting for more than 10 minutes or more, it is normal to measure the battery voltage of the car at 12.5V or higher. When the voltage of the battery is lower than 12V, it is proved that the battery is losing power. Need to be charged or checked

Matters needing attention in battery use(1) the rated voltage of the battery used must be 12V, and the capacity of the battery must be the same when replacing the battery. (2) when the vehicle is out of power, the crossing cable must have sufficient bearing capacity. (3) only cross-connected cables with insulation clips can be used to avoid positive and negative short circuits. (4) No battery may freeze below-10 ℃. Once the battery is found frozen, it must be thawed before it can be connected to the straddle cable, otherwise, it may cause an explosion. (5) when the battery is out of power, when using other vehicles to tie the electricity, we must ensure that the positive and negative electrodes are connected normally, and must follow the positive electrode first and then the negative electrode after the negative electrode. (6) the connection between the battery-free battery and the whole vehicle system must be correct.

The function of batteryWhen the engine starts, supply 200 ≤ 600A starting current to the starter (diesel engine up to 1000A) and supply power to the ignition system at the same time When the generator does not generate electricity or the voltage is low, it supplies power to the electrical equipment; when the generator is overloaded, assist the generator in supplying power When the terminal voltage of the generator is higher than the electromotive force of the battery, the electric energy of the generator is converted into chemical energy and stored. Using Voltage difference to absorb the overvoltage of Generator and protect the Electronic components of vehicle Battery or uninterruptible power supply for ECU memory
