Mercedes-Benz GLA250 Battery

The Mercedes-Benz GLA250 is a pretty straightforward vehicle in terms of battery replacement, since every model as of this writing uses a Group 48 (also known as an H6 battery) for which OPTIMA Batteries offers a direct-fit replacement with our DH6 YELLOWTOP. However, the BCI (Battery Council International) fitment guide does have some footnotes and other fitment information, that we would like to explain to you. Even though the BCI notes only run through the 2020 model year, this information is likely to remain unchanged for subsequent model years, until a major redesign is performed.
The first column indicates the production year and engine. The second column indicates footnotes that we can decipher for you. The 45 footnote indicates the battery in question is not a size identified by BCI and as such, you may need to contact your local Mercedes-Benz dealer for assistance. However, that is not the primary battery that starts your vehicle. Footnote 54 indicates the auxiliary battery is vented to the outside atmosphere. This auxiliary battery is also different than the primary battery that starts your vehicle and you may need to contact your Mercedes-Benz dealer for a replacement.
Footnote 66 indicates the CCA rating listed (760) is an EN Rating, meaning a European rating. The good news on this footnote is that regardless of the continent, the OPTIMA DH6 YELLOWTOP battery easily exceeds the requirement for the GLA250. The final footnote, 69, indicates the battery required for this application is an AGM (Absorbed Glass Mat) battery, which once again, is not a problem for OPTIMA, as all our batteries are AGM batteries.
The fifth column indicates the OE (Original Equipment) specification for Amp Hours. As you can see, the auxiliary battery is 12 Ah and the battery backup is 1.2 Ah. By comparison, the OPTIMA DH6 YELLOWTOP for this vehicle is rated at 72 Ah, so it is a significantly larger battery than the auxiliary or backup batteries. However, your local auto parts store may not carry either the auxiliary battery or backup battery, so you may need to at least contact your local Mercedes-Benz dealer to find out what size those batteries are, to see if a local retailer carries those batteries. If they do not, you may need to have them replaced at your dealership.
Fully-charged, the OPTIMA DH6 YELLOWTOP will measure about 13.0-13.2 volts and keeping the battery in your GLA250 fully-charged whenever possible will maximize both performance and lifespan. We're so confident this is the case, we will extend the free-replacement warranty coverage on your OPTIMA battery by a full year, if you purchase an OPTIMA Digital 1200 battery charger from us when you make your OPTIMA battery purchase.
