Question edited for clarity, and add MAKER, so few words, so many spelling mistakes!

Lithium batteries aren't rechargeable. Your small round CR2032 battery lasts 8 years. It is the same battery in a computer motherboard and easy to find in any pharmacy.

REPLACING 3V LITHIUM BATTERY The Auto-set time memory is maintained by a lithium button cell battery, model CR2032. The expected life of this battery is about 8 years. Be sure that the 2 "AA" batteries in the clock are fresh. The MODE switch (8) must be in the RUN position when replacing this button cell battery. This battery is located in the small round battery compartment on the rear of the clock secured by a screw. Open the battery compartment (3) with a screw driver and replace the CR2032 lithium battery observing the polarity. Then close the compartment securing with the screw.

I didn't know Mercedes Benz had a wall clock. If the clock was on the wall there should be a wheel at the back, when you turn it it will change the time, if you are talking about the clock in the car then the model and year would come in handy in answering the question
