W176
2013 - 2018Mercedes-Benz marks two 12 V batteries on this generation: one in the engine bay and one under the front floor on the right. The 2016 manual has you set the clock and fold the mirrors out once after the power has been cut.
Mercedes-Benz - A-ClassWe replace the 12 V battery in your A200 where it is parked, once a test has shown which battery the dashboard is really complaining about. The 2019 A-Class owner's manual calls for an AGM battery, and it links the Auxiliary Battery Malfunction message to the transmission's own small battery rather than the starter battery.
The name stayed the same, the electrical system did not. Find the years your car was built in and the differences that matter.
Mercedes-Benz marks two 12 V batteries on this generation: one in the engine bay and one under the front floor on the right. The 2016 manual has you set the clock and fold the mirrors out once after the power has been cut.
Two 12 V AGM batteries on the A 200 hatchback, engine bay and front cabin floor, plus a 48 V lithium-ion battery in the boot on cars built with the 48-volt system.
The A 200 saloon shares the hatchback's layout, with the 48 V battery under its own cover in the boot where one is fitted.

We match the replacement to the generation in front of us. These are the points Mercedes-Benz sets down for each.
| Point | W176 (2013 to 2018) | W177 (from 2018) |
|---|---|---|
| Battery technology | Matched to the label on the fitted battery | AGM, required by the 2019 manual |
| 12 V batteries | Two: engine bay and under the front floor | Two AGM: engine bay and under the front cabin floor |
| 48 V battery | None marked | Lithium-ion in the boot, where fitted |
| Charging and jump-starting | Connection point in the engine bay | Connection point in the engine bay |
| Highest charger voltage | 14.8 V | 14.8 V |
| After the power is cut | Set the clock, fold the mirrors out once | Reset the outside mirrors |
W176 figures come from the 2016 A-Class owner's manual, W177 figures from the 2019 manual and Mercedes-Benz's A 200 layout drawings.
We start our test from the exact wording on your display, because on the A200 each message points somewhere different.

We test both 12 V batteries on an A200, not only the one under the bonnet. Mercedes-Benz marks a second 12 V battery under the front cabin floor on the W177 A 200 and under the front floor on the W176, so a healthy engine-bay battery does not clear the car.
On a W177 built with the 48-volt system there is a third, lithium-ion battery in the boot. Knowing which of the three a symptom belongs to is what keeps the right part, and only that part, on the invoice.

Most of the car remembers itself. These are the items the A-Class manuals ask you to look at after the battery has been disconnected.
On a W177, ASSYST PLUS cannot count while the battery is out. Note the due date shown on the display before disconnection.
The 2019 manual says the mirrors need resetting before automatic folding works again: a brief press of the fold button.
On a W176, the 2016 manual has the clock set again through the multimedia system once power returns.
Fold the mirrors out once and the automatic folding function is back, as the 2016 manual describes.

On the W177 A200 sold from 2018, an AGM battery: the 2019 owner's manual says full vehicle functionality is only guaranteed with one. On the earlier W176, we read the label on the fitted battery and match its type and size. Replacement starts from AED 175 fitted, and the new battery carries our 1-year warranty.
Both the 2016 and the 2019 A-Class manuals tie that message to the auxiliary battery for the transmission, which is no longer being charged. It is not the starter battery. Until it is fixed, shift to P by hand before switching off, and apply the electric parking brake before you leave the car.
Mercedes-Benz marks two 12 V batteries on both generations: one in the engine bay and one under the front floor. A W177 A200 built with the 48-volt system also carries a lithium-ion battery in the boot. Our test shows which of them is behind the problem before anything is replaced.
Neither the 2016 nor the 2019 A-Class owner's manual lists a coding step for the 12 V battery. What the 2019 manual does ask is that the ASSYST PLUS service date is noted before disconnection and the outside mirrors are reset afterwards. Anything further your car needs, we explain at booking.
It can, through the jump-start connection point in the engine bay, which both A-Class manuals name for jump-starting and for charging. The 2019 manual adds that a petrol A200 should only take starting assistance with the engine and exhaust cold, and that any charger must stay at or below 14.8 V.
