Replacement of battery:

I got problems to start the engine when I have not used it for a week or so, find that the battery was out of power, it looks new but something wrong with it. And it was also only a 60 Ah capacity, it should be a 74 Ah battery. I bought a new 74 Ah Bosch battery and luckily it was a 25% discount these Christmas days and a three years guarantee. After a week without use I tried to start the engine today with minus 13 degree Celsius outdoor temperature, no problem, it started direct!

The battery is placed on the right side, just below front window.

Leak current:

I have found even with the new battery the car can be difficult to start when it had not been used for a couple of weeks. About three weeks in summer and one or two weeks in winter when cold. After have reading on internet for the corresponding Mercedes SLK I found that they say that Mercedes had problems these years. The electronic devices take to much current. Maximum shall be 0.09 Ampere or 90 milliamp.

I connected an Ampere meter on the minus pol of the battery in serie with the cable. I set the Ampere meters range to 20 Ampere, it take a lot of current the first seconds.

Direct when connected it takes 0.72 Ampere.

After about 30 seconds the current goes down to 0.27 Ampere, that's too much, but I think I didn't waited long enough time to let the current go down. With a current of 0.27 Ampere the battery shouldn't last for at most a week. I will measure it up more carefully later, but I don't think there is any problem with leak current, I just have to live with this because it's in the construction. They also give the recommendation that always have a fresh battery, replace every three years. The battery life time will goes down if it's deeply uncharged. From now and on I will always disconnect the battery or take it out and set it under charge if I will not use the car for a couple of weeks.

Cooling radiator clips:

When I replaced the battery I also see that the cooler radiator wasn't centered.

I found that there is a clip missing on the left side. More thing to do.
