W221
2005 - 2013The 12V battery sits in the engine bay at the bulkhead, on the passenger side of a left-hand-drive car. Cars built up to August 2008 add a second 12V battery on the right of the boot, so an early S500 has two to test.
Mercedes-Benz - S-ClassMercedes S500 Battery Replacement in Dubai, W221 to W223
We replace the 12V battery on every S500 generation, at your home, your office or wherever the car stopped in Dubai. Finding it comes first. A W221 keeps it under the bonnet, and cars built up to August 2008 carry a second one in the boot. The W222 and W223 keep the 12V in the boot, and the W223 adds a 48V lithium-ion battery under the bonnet.

Mercedes S500 by Generation
Each S-Class put the battery somewhere new. The build year tells the technician which panel to open before the van leaves.
W222
2013 - 2020One 12V battery in the boot, in the right-hand rear corner. The 2015 S-Class manual describes an auxiliary battery for the transmission, with its own warning when it stops charging.
W223
2020 - presentThe S500 4MATIC carries its 12V AGM battery in the boot and a 48V lithium-ion battery under the bonnet. The 12V side is the one we test and replace.

S-Class layouts
S500 Batteries by Generation, Side by Side
Three generations, three layouts. Find your build years before anyone lifts a cover.
| Item | W221 (2005-2013) | W222 (2013-2020) | W223 (2020 on) |
|---|---|---|---|
| Main 12V battery | Engine bay, passenger side | Boot, right rear | Boot, AGM |
| Extra battery | Second 12V in the boot, to 08/2008 | 48V units on cars with the 48V system | 48V lithium-ion under the bonnet |
| Where the technician works | Bonnet, plus the boot on early cars | Boot | Boot |
We read the build date from your VIN on the phone, because the W221 dropped its boot battery from September 2008.
W221 S500
Early W221s Carry Two 12V Batteries
An S500 built up to August 2008 has two 12V batteries, one at the bulkhead under the bonnet and one in the boot. Each is tested on its own, and only a failed one is replaced.
Later W221s keep a single battery under the bonnet. Your build date tells the technician which layout to expect, so the right battery is on the van.

S-Class manual
What the S-Class Manuals Ask For at the Battery
Four points from the 2015 and 2024 S-Class owner's manuals that shape an S500 battery job.
- AGM or Lithium-Ion OnlyThe 2024 S-Class manual guarantees full function only with an AGM or lithium-ion battery that meets the car's requirements. That is what we fit.
- Charging Through the BonnetEven with the battery in the boot, the 2015 S-Class manual routes charging and jump-starting through the connection point in the engine compartment.
- Park Lock Without PowerThe 2015 manual notes that the transmission locks in P once the battery is disconnected. The car stays where it is parked until the new one is in.
- 48V Catch-Up After a JumpAfter a W223 is jump-started, the 2024 manual shows Please Wait Charging 48 V Battery until the 48V side recharges.
Warning signs
S500 Warnings That Point at a Battery
Each of these is worth a test before anything is replaced.
Auxiliary Battery Malfunction, which the 2015 S-Class manual links to the transmission's auxiliary battery no longer charging
On a W223, the 2024 manual's advice for that message: select P by hand and apply the electric parking brake
Please Wait Charging 48 V Battery after a jump-start on a W223
A slow start after standing, the reason the 2015 manual asks for more frequent charge checks on cars left idle or used for short trips
Any no-start on a W221 built up to August 2008, where both 12V batteries are tested separately
Mercedes S500 Battery Questions
That changes by generation. The W221 keeps its 12V battery under the bonnet on the passenger side. Cars built up to August 2008 add a second one in the boot. The W222 and W223 carry the 12V battery in the boot, and the W223 adds a 48V lithium-ion battery under the bonnet.
Cars built up to August 2008 have two 12V batteries, one in the engine bay and one on the right of the boot. Later W221s carry the engine-bay battery alone. We read your build date from the VIN on the phone, so the technician knows which layout to test.
Yes. The W223 S500 4MATIC carries a 12V AGM battery in the boot alongside its 48V lithium-ion battery under the bonnet. The 2024 S-Class manual routes charging and jump-starting through the 12V jump-start point, and the 48V battery then recharges through the car's voltage converter.
The 2015 S-Class manual says the transmission's auxiliary battery is no longer being charged. The 2024 manual adds that, until it is repaired, you should select P by hand before switching off and apply the electric parking brake. Mention the message when you book, along with how the car starts.
Fitted prices start from AED 175. The figure for your S500 depends on its generation and the battery it was built with. It is confirmed for your car before the visit. Every replacement carries our 1-year warranty, and the old S500 battery is recycled.
Any step your S-Class needs after fitting is explained at booking. The 2015 S-Class manual does flag one thing: the transmission locks in P while the battery is disconnected. So the battery is changed where the car stands, and the car is not moved halfway through the job.
