Casil 12v 1.2ah Rechargeable Sealed Lead Acid Replacement Battery for Mercedes Auxiliary Battery, 12volt 1.2 amp Compatible with n0000004039 12v 1.2ah Mercedes

works perfect for my 2008 R350 Mercedes. saved $45 buying from this company instead of mercedes.. Thanks, i really appreciate it.

Good quality product no issues whatsoever

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! Well worth the cut! Money! and TIME SAVED! (Took me longer to write this review than to install without issue)

This was part of a multi item order from Amazon. Shipped immediately upon order but FedEx kept delaying delivery, finally got it way after the rest of my items.

As it was advertised!Thanks!

I bought this to use as an auxiliary battery in a Mercedes as a substitute as it is a lot less than the Mercedes battery. However, I guess this is another example of you get what you pay for. It arrived only partially charged. I tried charging with my charger. It would not take a charge, and ultimately failed. AND, moreover there is no mechanism to return this. You can only get support via making a phone call. An AWFUL experience.

As advertised

Works fine for aux batt on mercedes, terminals were opposite from stock but wires will reach to switch sides
