Reliable battery pack manufacturing at commercial scale

We provide battery pack manufacturing for OEMs who need dependable, repeatable production at commercial volumes. Supporting both build-to-print pack assembly and battery packs developed through our in-house design programmes, we manufacture at our UK facility using controlled and traceable processes.

Every battery pack manufacturing programme is structured to ensure quality, compliance and supply continuity from pilot builds through to long-term series production.

Build-to-print battery pack manufacturing

Our build-to-print pack assembly service provides a fast and controlled route to volume production. We manufacture battery packs to customer-owned designs, supporting DFM validation, sourcing, battery pack assembly and quality control within our factory in north-east England.

Build-to-print manufacturing suits programmes where the design is complete or nearing completion and the next priority is stable, high-quality battery pack production at commercial volumes.

  • Manufacture to customer drawings, BOMs and specifications
  • Support for final validation and production readiness
  • Scalable output from pilot build to series production
  • Controlled processes with full material and build traceability

Manufacturing battery packs designed in-house

Battery packs developed through our custom and platform-based design programmes are manufactured in-house using the same production systems, operators and quality controls as our build-to-print projects. Manufacturability is considered from the outset to ensure repeatable production, a predictable ramp-up, and fewer issues once designs are released for manufacture.

Process control and full traceability

Battery pack manufacturing at ABT is built around controlled processes, skilled operators and validated production systems. We utilise multiple battery assembly and welding technologies, selecting and validating the most appropriate method for each battery pack to ensure repeatability and performance.

Manufacturing execution systems guide operators through defined build steps, while validated measurement systems (Gauge R&R) and ongoing SPC monitoring confirm process capability and stability. Our integrated ERP system and product-specific control plans maintain full material and build traceability, ensuring every battery pack is produced under controlled conditions with complete visibility across components, parameters and production history.

Alexander Battery Technologies Testing

Quality assurance and supply chain discipline

Quality is managed proactively using established disciplines such as PFMEA, PPAP and stop-call-wait processes to prevent issues and control risk at the source. Product-specific end-of-line testing is developed in-house for each programme, verifying performance and safety before packs leave the factory.

Our supply chain is governed by strict supplier approval, first article inspection (FAI) and disciplined inventory control, including FIFO. Close oversight of supplier performance and full material traceability reduce manufacturing risk and support long-term production stability.

We have extensive experience managing global shipment requirements, including UN38.3, and work closely with UL to support compliance with standards such as IEC 62133 and IEC 62169.
