The battery provides the electrical energy required by the UV driver, but it does not by itself define curing performance. UV wavelength, irradiance, optical design, working distance, material sensitivity, exposure time and thermal behavior all influence the final curing result. On the battery side, we focus on stable discharge, protection behavior and thermal control. A 2S PCM/BMS can manage battery-level protection, while a 10k ohm NTC can provide thermal feedback when supported by the host electronics. Finished validation can include capacity, DC resistance, charge, discharge, high-load operation, abnormal charging, drop, vibration and temperature cycling. IEC 62133-2:2017 plus AMD1:2021 and applicable transport requirements provide the principal compliance framework.
