I'm replacing the battery in my 2007 MB E320 Bluetec. What steps are necessary to replace the battery besides just the physical removal and installation? Will I need to reset anything or do I need to have some sort of interim power applied while doing the replacement?

Your Mercedes does not require coding after a battery replacement.

I cannot figure out what size my current battery is. Here are some numbers seen on my battery: V4 6942912-08 18887.000.000 597426 10 - 6114-6942912-08 I cannot find matches for these numbers on either of your battery listings. Thanks for your help in figuring out what size I should get.

6114-6942912-08 / 6942912-08 = 61146942912 = 61146971370 which is a power distribution box. This is the part that connects to the positive battery terminal and does not correlate to a battery part number or battery size. You may need to remove this box in order to see information printed on the battery.

will it fit BMW 2013 Activehybrid 3? The recommended Ah is 92 and I think this battery has 94 Ah. So confused.

Yes. It's the same battery size. The AH is not as important since the battery requires registration via the IBS once installed.

I have a 2011 BMW X5 xDrive50i. Can you recommend an appropriate (an reasonably cheap) tool to register the battery after installation? Preferably a tool offered through FCP Euro.

The Autel MD808P is the entry-level tool to perform service functions.

Does this fit the 2014 bmw x3 f25 n20 xdrive?

Yes, it does.

2008 328xi sedan manual transmission and the part number on the battery that is currently installed is 61212353810. Will this battery be ok? The other one that comes up on your site is the 94R so I am confused as to which I need. Thanks.

Yes, it will be.

I have a 2010 bmw 528i xdrive, the current battery inside is 95R. Would this 49 be able to fit in place of the current battery? Thanks in advance

We always recommend replacing your battery with the same size that originally came in the vehicle.

Is there a core charge? Can I send my old battery to you for recycling or should I drop it at a local facility?

There is no core charge for this battery and we cannot accept battery cores. You can take your exiting battery to a local recycling facility for disposal.

Just checking to be sure this battery fits my 2007 e93? I understand that I will need to have it coded and registered. Thank you

There are three possible battery sizes for your vehicle, group 94R, group 48, and group 49. You need to visually identify the group size installed in your vehicle before ordering. Upon installation, a battery registration is required.

I drive an RWD 2008 535i, the fitment notes say "Size 49, replace with same spec as original battery installed," will this work for my vehicle?

It may, would recommend identifying the battery in your vehicle currently and confirming the fitments.
