recell.store, a UK online marketplace for used electric vehicle batteries and a subsidiary of Altilium, has launched the All Battery Index (ABI), a monthly benchmark that tracks the market value of end-of-life EV battery packs in the UK. The ABI aims to provide a standardized reference for second-life use and recycling, addressing the lack of transparency and pricing consistency in the growing used battery sector

The May 2025 edition of the index includes data on the 15 top-selling EV models in the UK. According to recell.store, the Audi Q4 e-tron and Polestar 2 held the highest value, based on real-time market data and the company’s proprietary grading and pricing framework. The index is available online at www.recell.store/abi-benchmark-index.

The ABI uses a structured valuation model incorporating parameters such as state of health (SOH), state of charge (SOC), remaining capacity, pack size, and metal recovery potential. Battery packs are assigned R Grades—R1 to R4—based on their suitability for reuse or recycling. For example, R4 batteries with SOH and SOC above 80 percent are considered suitable for second-life use, while R1 batteries are deemed unsuitable for reuse.

“The ABI is a key step toward unlocking the true value of used EV batteries and bringing structure to a fragmented and opaque market,” said Dr Christian Marston, Chief Operating Officer at Altilium. “We believe the ABI will become the go-to benchmark for battery reuse and recycling in the UK.”

Rod Savage, Head of Operations at recell.store, added, “Our vision is to make end-of-life battery trading as transparent and efficient as trading any other commodity. ABI provides the pricing backbone for that ecosystem, helping participants navigate this emerging asset class with confidence.”

The launch of the ABI expands recell.store’s offerings, which already include a wide inventory of used battery packs for sale across the UK. The platform supports transactions between dismantlers, OEMs, insurers, and other stakeholders in the battery reuse and recycling value chain.
