[GarrettLynn]

The battery can be charged directly in the car. The steps for charging the battery are: 1. Ensure the engine is turned off and remove the battery from the car; 2. Place the battery in a ventilated, cool, and open area, and open the vent caps on the battery; 3. Wear goggles and rubber gloves, attach the charger's red clamp to the battery's positive terminal marked with a plus sign, and the black clamp to the negative terminal marked with a minus sign; 4. Select the slow charging mode, set the gear to 2, and choose a 12V power source; 5. Plug in the charger, turn on the switch after powering on, and start charging. Precautions for battery charging include: 1. Check the electrolyte level before charging; 2. Measure the electrolyte density and voltage approximately every hour during charging and monitor its temperature; 3. Ensure the charging area is well-ventilated and strictly prohibit open flames; 4. Stop charging if unattended.
