Why Battery & Charging Health Matters

A healthy battery is essential — but so is a functioning charging system. Issues with the on‑board charger, charge‑port, 12V system or thermal management can cause slow charging, failed rapid‑charging sessions or complete charging refusal. This certificate confirms the entire system is working as it should.
