[소느로] 일렉트로룩스 PURE Q9ㅣ청소기 배터리 리필ㅣ배터리 교체

I refilled the battery in an Electrolux cordless vacuum cleaner I received from Carrot. The exact model is PQ91-30B. The LG 18650 HD2 high-discharge battery was completely discharged, so I replaced it with a special-grade battery of the same model. The video explains the disassembly process of the PURE Q9 vacuum cleaner in an easy-to-understand manner, and also provides tips for avoiding confusion with wire placement during the soldering process. The battery used for the refill was provided by the online DIY cafe "Lithium Battery DIY Lab" for research purposes. https://cafe.naver.com/lithiumbatterie
