How to Charge a BMW Car Battery?

[EmmanuelDella]

BMW car battery charging method: Open the hood, lift up the positive terminal clamp, and there is a grounding cylinder inside the hood. Connect the charger to start charging. Below is relevant information about BMW car batteries: 1. New batteries often do not reach full capacity after the first charge and should undergo a discharge cycle. 2. Discharge at a 20-hour rate (i.e., discharge with a current equal to 1/20 of the rated capacity until the cell voltage drops to 1.75V), then recharge with the appropriate current. 3. As long as the engine is running and the alternator is functioning properly, it will generate electricity, and the alternator will charge the battery. 4. When the battery is fully charged, charging will stop. As long as the battery's energy is not depleted, there is no need to charge it. The alternator charges without interruption and has no fixed time; it adjusts the charging current based on the battery's charge level.
