S400 Hybrid Parts

Rebuilt Mercedes-Benz S400 Hybrid Battery — Built by the People Who Know These Cars Inside Out

Your S400 is telling you the hybrid battery is done — and the dealership just quoted you around $15,000 to fix it. There's a better way.

We are one of the original S400 hybrid troubleshooting specialists in the USA. Owners ship us their cars from California, Texas, Florida — all over the country — because we've diagnosed and repaired more of these hybrid systems than just about anyone. This isn't a side business for us. We know exactly how these batteries fail, exactly how to rebuild them right, and exactly how to test them before they leave our shop.

Why buy from us

✔ Plug and play — no programming needed. Install it and your car starts. No dealer visit, no coding, no surprises.

✔ Fully tested before shipment. Every battery is rebuilt and load-tested in our Baltimore, Maryland facility. Nothing ships until it passes.

✔ 1-year warranty with free replacement. If the battery fails within 12 months, we replace it — free. (Labor and return shipping to Baltimore are not covered.) You're dealing with a real US shop with a real address, not an anonymous seller.

✔ Fits ALL 2010–2013 S400 Hybrids. Even if your part number isn't listed below, this battery fits every 2010, 2011, 2012, and 2013 Mercedes-Benz S400 Hybrid. Not sure? Message us your VIN and we'll confirm.

Before you buy a "cheap" battery on eBay or AliExpress — read this

We rebuild a lot of batteries for customers who bought elsewhere first. Here's what they tell us:

The "1-year warranty" on eBay/AliExpress is often a joke . Many listings advertise a 1-year warranty, but in practice only eBay's own money-back window applies — a limited number of days. After that, you're chasing a seller who stops answering messages. We've had many S400 owners come to us after fighting for months to get a warranty claim honored and losing.

Untested batteries are a gamble. Cheap imported batteries often arrive untested. Some fail within months. Getting one back to China for a refund? Good luck. You'll pay a fortune in shipping — if the seller responds at all.

With us, the warranty is real. We're in Baltimore, Maryland. If there's a problem within 12 months, you send the battery back and we replace it. Simple as that.

Important installation notes

After replacing the hybrid battery, have your A/C system charged. The car will start without it, but the A/C system cools the hybrid battery — running with a discharged A/C system shortens battery life. We strongly recommend a fully working A/C system.

Want us to install it? Ship or bring your car to us

Many customers ship or drive their S400 to our Baltimore shop for professional installation and a full hybrid-system checkout by the technicians who specialize in these cars. Contact us for an installation quote — it's often the fastest, safest way to get your S400 back on the road with total peace of mind.

Shipping & pickup

These batteries are sensitive to rough handling, so we ship ground only — never air freight. Delivery typically takes 4–5 business days from Baltimore, Maryland. Local pickup is welcome — contact us for pickup pricing if you plan to install it yourself.

Dealer price vs. our price

Mercedes-Benz dealerships charge around $15,000 to replace the S400 hybrid battery. Our rebuilt, fully tested battery with a 1-year warranty costs a fraction of that — and it's backed by the shop that knows these cars better than anyone.
