CeLLife Technologies, a Finnish deep-tech company developing a battery quality and health intelligence platform, has closed a €4 million (~$4.6 million) post-seed funding round.

The round included the European Innovation Council, new investors 2C Ventures of Estonia and Butterfly Ventures of Finland, and existing investors, including France-based Ventech.

The company said it will use the funding to scale commercial operations across Europe and North America. Its target segments include battery recycling, module and pack assembly quality control, and condition monitoring for battery energy storage systems.

“This funding enables us to accelerate the commercial rollout of CeLLife’s battery quality and health intelligence platform,” said Roni Luhtala, Co-founder and CEO of CeLLife Technologies. “Battery manufacturers, recyclers, and energy storage operators all face the same challenge: they need faster, more reliable visibility into battery quality, condition, and performance. We are building the diagnostics and decision-support infrastructure needed across the full battery lifecycle.”

The company’s platform is built around its patented Electrical Fingerprint technology, which it says captures battery measurement data in seconds and converts it into diagnostics, traceability, and decision-support outputs.

CeLLife said the technology is chemistry-agnostic and works across nickel manganese cobalt, lithium iron phosphate, nickel cobalt aluminum, solid-state, and sodium-ion cells. The company also said the technology is protected by multiple granted patents.

According to the company, its platform aligns with demand for battery traceability, lifecycle intelligence, and digital records under the EU Battery Regulation, including battery passport requirements coming into force for relevant battery categories from February 2027.

VC funding raised by Energy Storage companies in Q1 2026 increased 9% YoY, with $1.2 billion in 26 deals compared to $1.1 billion in 18 deals in Q1 2025, and a 44% increase in deal count, according to Mercom’s Q1 2026 Funding and M&A for Energy Storage report.

In 2024, Zitara, a battery management software provider, closed a $17 million Series AA funding round led by Salesforce Ventures, with participation from Emerson Ventures, Chevron Technology Ventures, Energy Impact Partners, and Climate Capital.
