I bought a new battery for my 2000 ML55 from Advance Auto Parts.
The battery looks identical to the factory, with the handles, same
casing, with a sticker stamped "Made in Spain" just like the
MB battery. It has 3 year full exchange warranty and another 5 years prorated warranty for $119.99 vs. MB battery which is like $170++ with only 2 year warranty.
This $119.99 also includes installation. The original price was $127.88 but they
matched autozone battery price which has the same warranty. This is a good deal.
