Shipping was fast. But unfortunately I couldn’t use the battery as I ordered the wrong one. Mighty Max refunded without taking back the battery. I ordered the right battery immediately and received it fast again and it works awesome. Thank you for a great product at an affordable price and kudos to the great customer support. Keep it up!

The battery has worked well so far. Installing was a bit of a pain – took me about an hour. Recommend that aside from removing the side plastic as the youtube videos show, you also loosen the cover plan underneath the steering column (3 Torx screws) – that will make it easier to position the battery back in its holder. The vendor was responsive when I asked for an adjustment in shipping cost due to delayed arrival. Recommended.

A little challenging to install, but it fits fine. Terminals are on the opposite sides, but that is not a problem.

yep I bought one –
I checked vin number, and year/model of car with the add to make sure I was getting correct battery. Unfortunately i wound up moving and didn’t get an opportunity to change the battery until 3 months after receiving it. Turns out my E 350 is one of the ones that doesn’t use a second battery. Now I’m stuck with a battery I have no use for.

Works on benz s550!

I followed a YouTube video for my W221 frame, which has this small battery behind the fuses, on the driver’s left side of the console. Accessed from the left side panel, did not have to lie on my back and come in from below the steering wheel. Terminals on this model are swapped from the Benz original, but there was zero problem in switching the leads to match. Size was an excellent fit to the battery holder, and there was just some tedium in working in the small space behind the console. Auxiliary Battery Malfunction warning automatically cleared with no further action on my part.

Nothing to dislike, perfect fit.

Just as described best value for the money. Just remember the posts are switched from the original OEM battery on the benz so remember to reverse the wires when you plug it up.

Fits and works like the original, pay attention because the post are reversed as opposed to the original but for the price it’s perfect.

Good replacement for Aux battery for 2013 model year for MB w212

So far it’s a solid alternative to MB battery. It’s slightly smaller, which makes it fit a little loose in mounting bracket. Posts are also opposite of the MB battery.

Replacement auxiliary battery for 2011 Mercedes Benz E350. It is mounted inside the dashboard on the left side. Had to remove the under cover below the steering wheel and also remove the side panel of the dashboard to get to the battery. Battery works great.

Perfect fit

Fits fine except for terminal on positive side was too small, compared to original battery. Soldered a larger terminal to battery and all is well. Time will tell if it holds up. Don’t see a problem and not concerned as the cost was about a quarter of what M/B battery would have been. Pleased with purchase and would recommend this item.

Replaced my old battery that couldn’t hold a charge. Works like new. For reference, my mower is a Honda HRR216VLA.

Works perfect..plug n play. No need to purchase OEM battery
Ralf Weiser –
Great price and it does appear to work. The battery poles are switched though and that could have caused a big issue had I not noticed that.

This battery replaced my failed OEM part in my 2010 E350. The procedure is simple and doable by the average DIY mechanic. See youtube(dot)com/watch?v=iHSe02xl8LE for some guidance. I added a piece of dense rubber foam to make battery fit well within the bracket, as the new battery is a bit smaller than the OEM part. The whole procedure took me less than 30 minutes. No more Auxiliary Battery Malfunction message at a cost far below the price of a dealer repair.

Works fine on w212. It’s quite a chore to install, but is an easy job for your typical mechanic. I did it myself, and it’s tricky to get your hand up in the dash to connect and disconnect terminals – – I had to do it from outside of the vehicle. A Mercedes dealer would probably charge an exorbitant $200+ for this repair, so my 2 cents advice for the average owner would be to get the battery and a T25 torx driver, and just take it to a local mechanic shop for the installation.

Perfect fit in my 2012 Mercedes Benz ml550. Time will tell how long it lasts, but very happy so far.
