(b)(4).The sample was returned for evaluation.A visual exam was performed and no defects were observed.An attempt was made to charge the cartridge with the charging unit that is shipped in the kit with the handle and led cartridge.The red glowing charging light would not energize.The cartridge was destructively inspected.Visual signs of corrosion were found on top of the lithium-ion battery and the small led electronic driving module.The complaint has been confirmed.The lithium-ion battery leaked causing destructive corrosion inside the led cartridge housing that prevented the battery from charging.Corroding batteries could be the result of age, extreme heat and/or cold, or contact with other corrosive materials.A root cause for the issue could not be determined.A conclusion code could not be chosen as the complaint was confirmed; however, a root cause was not established.
