SUSTAINera, the circular-economy parts business inside Stellantis, has extended its remanufactured range to high-voltage batteries for most battery-electric and plug-in hybrid models across the group's brands. The parts go on show at Automechanika Frankfurt from 8 to 12 September 2026.

Stellantis sells Peugeot, Citroen, Opel and Vauxhall, Fiat, Jeep, DS, Alfa Romeo and Lancia EVs across Europe. A factory-remanufacturing channel spanning that range means a large slice of Europe's ageing electric fleet has just acquired an official second option for its single most expensive component.

What is in the range

Alongside the batteries sit an electrified dual-clutch transmission for mild hybrids and an electrically driven air-conditioning compressor that until now was only remanufactured for combustion cars. Stellantis says the parts are rebuilt to OEM specification, "with the same performance characteristics and warranty conditions as MOPAR original parts", and that remanufacturing saves up to 80% of the raw materials and up to 40% of the CO2 of building new.

The number that is missing

There is no price. There is also no per-model list, no stated warranty duration, no market-by-market availability and no guaranteed usable capacity for a rebuilt pack. This was announced as an aftermarket trade-fair proposition, aimed at independent workshops rather than at owners, and the detail an owner most needs is the one not given.

Tesla published the opposite half

When a remanufactured Long Range pack appeared in Tesla's public parts catalogue at $8,000 against roughly $14,500 new, the warranty, the rebuild specification and the capacity guarantee were all absent. Stellantis has answered two of those three and withheld the price instead. Between them the two announcements still do not answer the question that decides everything: what capacity a rebuilt pack is guaranteed to return. A reman battery that restores a car's original range is a different product from one that returns it to 85% of it, and neither company will say which it is selling.

Why this reaches a Tesla owner

Out-of-warranty pack replacement is the largest unpriced risk in electric-car ownership, and it is priced into used values whether or not anybody publishes a figure. It stops being one manufacturer's parts listing and starts being a market when several manufacturers run factory-reman channels at the same time, with independent specialists such as the battery repair centre that opened in Doncaster competing underneath them, and cell-level repair networks like CATL's Ning Service attacking the same problem from the other end.

That is the mechanism that will decide what a five-year-old electric car is worth at the end of this decade, and it is why a Stellantis parts announcement belongs in a Tesla owner's field of view. The competitive pressure runs the right way for buyers: once one group publishes a price and another publishes a warranty, the third has to publish both.
