CLK 55 AMG Battery
I am looking to replace the battery on my 2004 CLK55 AMG. The car currently has a Bosch S4 battery. The problem that I am having is that the battery is running low after a week or so if I do not use the car. The car starts fine but the instrument cluster is blank until I drive the car for 30 mins or so.
I am not sure if the Bosch S4 type 19 is the right battery for this car. Can someone confirm?
Would be OK for me to purchase a Bosch S5? The spec on the S4 is 800A and 95AH. The S5 is 830A and 100AH.
Thanks!




thanks for the advice. I am in the UK and I got a price from the dealer of around £280’s which seems a bit steep as they only offer a 2 year warranty.
I can get the Bosch s5 for £150’s with a 5 year warranty. I will try another MB dealer tomorrow and look into AGM batteries
Update:
The dealer made a mistake when he quoted me £280, this was for a AGM battery. The price for the battery for my car is £160’s is which is reasonable.,,
