Learn how to install a new OPTIMA H6 battery in a Mercedes Benz GLC300. We’ll show you how to replace/change/remove with simple tips and tricks to help get you started!
Tool List: 10mm wrench, T45 torx
We’ve replaced the original battery with the OPTIMA H6 flat plate AGM battery in this 2016 Mercedes GLC300. Although this video may provide you with the basic procedures, we recommend that you check with the vehicle manufacture’s step by step procedures found in service/repair manuals for the vehicle you are working on.
Even if your vehicle did not come with an AGM battery, you can upgrade to an AGM battery for up to 2x the life. AGM can be found at most retail outlets. You can learn more about AGM here: https://www.autobatteries.com/en-us/battery-technology-types/absorbent-glass-mat-agm-battery
The use of a memory saving procedure will keep the memory alive on the vehicle’s computer during the battery replacement procedure. Referring to our Memory Saving video will provide you with various memory saving procedures that can be used according to vehicle manufacturer’s requirements. https://youtu.be/vSP3ShcaFgQ
Some late model vehicles must have the 12 volt battery registered with the vehicle’s Battery Control Module or Computer after replacement. See these videos on Battery registration and coding for more details on the procedures at https://youtu.be/TGKohKZHzr0 & https://youtu.be/cxOK_DczRGg
Always wear safety glasses and gloves when working with or near batteries.

Thanks a lot !
Hi, can i use my CTEK mxs 3.8 charger as a memory saver in this Mercedes?
This kind of memory saver is useless if it's hooked to the positive battery terminal. Use a jump starter with a cigarette lighter socket and obd2 memory saver cord.
So the battery in this 2016 GLC300 didn't require the new battery to be being registered with the BCU you spoke about?
So I assume you do have to program the computer on this car for a new battery?
Awesome video, guys. I put this battery in my GLC, and this was very helpful.
Hello could you show how to replace auxiliary battery? Thank You
Very good, long awaited video! Is this process same for AMG GLC43? What kind of battery memory saver you are using here?
