Mercedes EQS battery replacement: €55,000 for a used pack
A Mercedes EQS owner in Croatia needs a new battery after 300,000 km. Mercedes quoted €55,000 for a refurbished one, while the maker's price is estimated near €12,000.

Buying a used electric car is a gamble, and one Mercedes EQS owner has just found out how expensive losing can be. After 300,000 km, his battery is finished, and Mercedes wants €55,000 for a replacement. A refurbished one, at that.
The owner noticed the battery was draining unusually fast and took his EQS 450+ to a Mercedes dealer in Croatia. The diagnosis was blunt: seriously damaged cells and an imbalance caused by self-discharge. The pack was so worn that its modules could not be repaired one by one, so a full replacement was the only option.
There is a catch. Mercedes no longer produces batteries for this version of the car, so the only thing on offer was a reconditioned pack. The price for that used part: €55,000.
Is the Mercedes EQS battery under warranty?
Not here. Like most brands, Mercedes covers its batteries for 8 years or 160,000 km. This car has nearly doubled the mileage limit, so the owner pays.
How much does an EQS battery really cost?
EV Clinic, a company that specialises in servicing electric vehicles, went to the headquarters of CATL, the battery supplier, to find out what an EQS cell is worth. Their estimate was around €12,000, far below the Mercedes quote. The company thinks the gap probably applies to other carmakers too.
Its advice is to fit a compatible used battery costing at most €15,000 instead. Even with labour added, that would stay well under the refurbished price.
Some of the high figure may come from sheer size. The EQS is the electric counterpart of the S-Class, and the 450+ carries a battery with 107.8 kWh of net capacity, good for 780 km of range. After the facelift, the limousine gets a 122 kWh pack and up to 925 km.
