Only difference is the polarity is reversed... - Fits the Mercedes ML 350 perfectly! Same size, same volts, same amp hours. Everything is the same. The only difference is the polarity is reversed (The positive on the OEM Battery is where the negative post is and the negative post is where the positive is ) The posts are only about an inch apart so its NOT an issue at all. It is clearly marked Red and Black so unless you're an idiot you won't hook it up wrong. Put red clip where Red post is and Black to black! dahhhh. Also I watched a you tube video on How to R&R found one that said make an incision on the side carpet in the med bag holder and you're in ! SAVES 3 hours of Labor! your in and done.done!
