Rebuilt S400 Hybrid Battery From The Shop That Made The Videos
If you or your mechanic learned how the S400 hybrid system fails by watching YOUCANIC on YouTube, this is the battery we install in our own Baltimore shop. Rebuilt and load tested here, plug and play with no coding, and covered by a 1 year replacement warranty from a company with a phone number and an address.
Battery Or Power Electronics? Confirm Before You Buy.
A no start, a red battery warning or a hybrid system message on an S400 can come from the high voltage battery or from the power electronic module, and the two are often confused. We regularly see cars where the wrong one was replaced first, usually with a part bought online that "did not work."
Send the fault codes from a full system scan and your VIN to support@youcanic.com, or call 1-888-959-4265, and we will tell you which part the codes point to before you spend $2,450. No charge, no obligation.
Watch Before You Order
We published the diagnostic and replacement videos for this system years ago, and they are still the ones mechanics watch. This one covers how the S400 hybrid battery fails and what the warning signs look like.

Why This Matters More Than The Price
A lot of S400 hybrid batteries are sold online as used, untested or "new" imports, with a 1 year warranty printed in the listing. eBay's own buyer protection runs 30 days from delivery. After that, the warranty is only as good as the seller's willingness to answer a message, and many stop answering.
We know because those owners call us. Every month we hear from people whose battery from another seller failed at month four or five, who could not reach the seller, and who are now paying for the part and the labor a second time. The cheap battery was the expensive one.
If a battery we rebuilt fails inside a year, you get another one. That is the whole policy.
What It Costs Elsewhere
| Option | What you pay | What you get |
|---|---|---|
| Mercedes-Benz dealer | Around $15,000 installed | New battery, dealer labor, dealer warranty |
| Used or import battery online | Less up front, then labor twice if it fails | Usually untested; warranty depends on the seller after 30 days |
| YOUCANIC rebuilt | $2,450 for the battery; installation is a separate service | Rebuilt and tested in the USA, plug and play, 1 year replacement warranty, technician support included. Installation at our Baltimore shop is quoted separately |
Installation Notes
- • Recharge the A/C system after the install. On the S400 the hybrid battery is cooled by the air conditioning circuit. The car will start with the A/C discharged, but running that way shortens the life of the new battery. A working A/C system is part of the repair, not an option. If the electric A/C compressor is weak or dead, replace it in the same visit: rebuilt S400 hybrid A/C compressor.
- • High voltage. Disable the hybrid system per the procedure in our video and wear insulated gloves. If you are not comfortable with high voltage work, have a shop do it or bring the car to us.
- • Scan the car afterward. Clear the stored hybrid codes and confirm no new ones set. Our UCAN-II Pro reads the S400 hybrid modules; so does the dealer tool.
- • Want us to do it? Installation is not included in the $2,450 price; it is a separate service at our Baltimore shop. Owners drive or ship their S400 to us for installation, A/C recharge and a full hybrid system check by the technicians who work on these every week. Call 1-888-959-4265 for an installation quote.
Shipping And Pickup
The battery weighs about 60 pounds and is a lithium ion pack, so it ships by ground only, never by air, from Baltimore, Maryland. Delivery is usually 4 to 5 business days in the continental US. Shipping is calculated at checkout.
Local pickup in Towson, Maryland is available by appointment. Contact us for pickup pricing if you are installing it yourself.

Frequently Asked Questions
How do I know it is the battery and not the power electronic module?
Scan the hybrid system and read the codes. Codes that point to the high voltage battery, cell balance or battery state of health mean the battery. Codes that point to the inverter, converter or power electronics mean the module. If the picture is mixed, email us the codes and VIN before ordering; we diagnose these every week and will tell you which one you need.
Will the car start right after installation?
Yes, as long as the battery was the fault. The battery is plug and play and needs no programming.
My part number is not in your list. Will it fit?
Yes. One battery fits every 2010 to 2013 S400 Hybrid regardless of the number on the original. Send your VIN if you would like it confirmed in writing.
What does rebuilt mean here?
The pack is rebuilt in our Baltimore shop and load tested before it ships. It is not a used battery pulled from a salvage car and resold as is.
How does a warranty claim work?
Email or call with your order number and the codes. We confirm the failure with you, you ship the battery back to Baltimore, and we send a replacement. Labor and return shipping are the only costs not covered.
Does the price include installation?
No. $2,450 is for the battery only, shipped to you or picked up in Towson. Installation is a separate service with its own quote.
Can you install it?
Yes, as a separate service. Drive or ship the car to our Baltimore shop and we install the battery, recharge the A/C and verify the whole hybrid system. Call 1-888-959-4265 for an installation quote.
Can I pick it up?
Yes, by appointment in Towson, Maryland. Contact us for pickup pricing.
Is there a cheaper way to keep the car running?
Some owners choose our starter motor retrofit, which lets the gasoline engine start on its own when the hybrid system is down. It is a different repair with different trade offs; watch the retrofit video linked above and call us to talk it through.
