• Find it in the hood. It is commonly located in the engine compartment.
• Loosen and remove the negative (-) battery cable first, then the positive (+) cable using a wrench or socket set.
• Check the battery terminals for signs of corrosion. If it is there, use a cleaning brush to gently clear it.
• Attach the positive (+) charger cable to the positive (+) battery terminal.
• Then connect the negative (-) charger cable to a metal part of the engine block or chassis. Do not attach it directly to the negative (-) battery terminal.
• Select the mode of operation of the charger equivalent to lead-acid batteries.
• [Plug in and turn on the charger] For specific charging times and settings, please follow the charger manufacturer’s instructions.
• Dispatch of charger from power outlet after the battery is charged fully
• Disconnect the charger cables in reverse order: negative (-) first, positive (+) second.
• Reconnect the battery terminals, first the positive (+), then the negative (-). Make sure to fasten them tightly.

If your Mercedes is equipped with a lithium-ion battery, the charging process is a little different. Follow these steps:

• You need to find the battery of your car. Most lithium-ion batteries are located in the trunk or under the rear seat.
• Inspect the battery terminals for corrosion or damage. Clean the terminals if needed.
• Attach the positive (+) charger cable to the positive (+) battery terminal.
• Attach the negative (-) charger cable to a metal component of the vehicle’s frame, away from the battery.
• Change the charger to the lithium-ion battery charging mode.
• However, make sure you plug the charger into the socket and switch it on. Refer to the manufacturer of the charger for specific times and settings for charging.
• When the battery reaches a full charge, disconnect the charger and the power supply.
• Cables from the charger disconnect: (-) negative cable first, followed by the (+) positive cable.
