Ensurge lands multi-year development pact with wearables giant

Ensurge Micropower ASA has signed a paid, multi-year development agreement with a leading global technology company to build a custom solid-state microbattery for next-generation devices. The deal gives Ensurge a structured path toward high-volume manufacturing if the program hits its milestones.

Why it matters: - The agreement gives Ensurge a funded route from prototype work to potential mass production with a major customer. - The customer wants a battery that fits ultra-compact devices while delivering high energy density, safety, and long-term reliability. - The deal adds commercial validation for Ensurge’s solid-state microbattery platform and could support future revenue if development succeeds.

What happened: - Ensurge Micropower ASA entered into a multi-year, multi-phase, paid development agreement with a leading global technology company. - The work covers the design, development, and delivery of a customized solid-state microbattery. - The company announced the deal on October 22, 2026, from San Jose, California. - Ensurge said the parties intend to move toward high-volume manufacturing after successful completion of the development program.

The details: - The program starts with proof-of-concept and then moves through engineering validation, design validation, and process validation. - Each phase includes milestone-based deliverables. - The customer funds each phase after satisfactory completion of the relevant milestones. - The parties plan to negotiate a supply agreement during the final phase, if the development milestones are completed successfully. - Ensurge said the battery is being developed for the customer’s next-generation devices. - The customer is described as a global technology leader with a track record of bringing high-volume consumer products to market. - Ensurge said this is its second active development agreement, alongside a previously announced joint development agreement with Corning Incorporated. - The company said it has a pipeline of more than 125 inbound leads and is in active discussions with more than a dozen top-tier potential customers across multiple applications. - Ensurge develops solid-state microbatteries for wearable, medical, and connected devices. - The company says its proprietary thin-film deposition processes support high energy density, small form factor, and long-cycle life batteries for space- and power-constrained applications. - Ensurge is headquartered in Oslo, Norway, with operations in San Jose, California, and is listed on Euronext Oslo Børs under the ticker ENSU. - More information is available on Ensurge’s website. - The company also shares updates on LinkedIn.

Between the lines: - The milestone-based structure lowers risk for both sides by tying funding to progress. - The second development agreement suggests Ensurge is trying to turn technical interest into repeatable customer traction. - A future supply agreement is not guaranteed, but the program creates a formal path to one.

What's next: - Ensurge and the customer will work through the development phases in sequence. - The companies are expected to discuss a supply agreement during the final phase if technical targets are met. - Success could position Ensurge for qualification and eventual high-volume manufacturing.

The bottom line: - Ensurge has secured a paid development program that could move its microbattery technology from validation to commercial production if milestones are met.
