In the process of installing a wood/leather steering wheel, I disconnected the battery just to be safe. I took the opportunity to visually check the condition of the battery to see if I need to proactively change it. This is a 2000 E320 that I bought about 3 months ago with no knowledge as to whether the battery has been replaced or not. It is the OEM battery. Visually speaking, the battery looked new. Functionally, there are no signs of electrical weakness anywhere.
In speaking with the parts department at the MB dealership, a customer who was standing in line, told me that all I had to do is to check on the battery every 6 months or so and ADD WATER!
My questions: Has anyone on this forum had to periodically add water to the battery? Do I just use regular tap water? And how do I fill it?
I had thought that the battery would be maintenance free, but the same waiting customer told me that maintenance free is he worst thing that ever happened to batteries. They also told me that Optima batteries will last a maximum of two years, while MB batteries, with proper maintenance in a moderate climate, can go 10 years!
