Learn how to install a new auxiliary battery in a Mercedes-Benz GLA250. We’ll show you how to replace/change/remove with simple tips and tricks to help get you started!
Tool List: 10mm wrench
The 12 volt auxiliary battery in this 2015 Mercedes-Benz GLA250 is located in the passengers foot well. 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.
If you need to replace cabin filter do it while battery is removed. Battery needs to be removed in order to take out and replace new filter.

Super nice and detailed explanation. My MB dealer charged me a bomb for battery replacement+Labour+diagnostic for the main battery. For Aux, I guess I can DIY.

I have an (W176) A200 2013, Regarding the replacement of this auxiliary battery, would you tell me if it is like the main battery "do not remove the 2 cables without making a bridge"? or can i replace this battery like any other battery, removing the 2 cables (first negative, then positive), installing the battery? do I need to run a scanner to remove the "auxiliary battery failure" message from the panel?
Does this battery run the Collision Prevention Assist? Ty
