CAP-03 · Testing & aging

No module leaves before its cycles are done.

Formation and aging racks cycle every VoltBridge module against its project profile, and a UN 38.3 pre-compliance bench screens transport-critical risks in house — altitude, thermal, vibration, shock and short circuit. Formal certification runs through accredited third-party labs.

The aging discipline

Cycled in, data out.

Aging is where early-life cell failures are caught — or missed. Modules sit through programmed formation and rest windows, and every cycle is logged against the module's serial number so a field question is answered with batch data, not guesses.

  • Programmed formation cycles set per project, with per-channel logging.
  • High-temperature rest and cycling windows tuned to the destination market.
  • Cycle curves and end-of-aging capacity archived against serial numbers.
  • Pre-compliance screens run before samples ever reach an accredited lab.

Certification scopeIn-house pre-compliance testing; formal certification through accredited third-party labs

UN 38.3 rows describe in-house pre-compliance testing; formal certification is carried out by accredited third-party labs. Batch cycle data and pre-compliance records are shared with customers under NDA on request.

Need cycle data before you commit?

Ask for the aging records and pre-compliance screens tied to a sample batch. We ship data with hardware, so your validation starts before the first purchase order.
