Hello All - Has anyone replaced the batteries for the W211 TPM sensors on the rim? I am about to buy a new set of tires and thought I should just replace the batteries before they run out. I don't want to take the tire off to replace the batteries before I need new tires again.

I am interested in the size of the battery and how difficult it is to replace the batteries for all 4 wheels.

Thanks...
