The battery is a PSE-compliant product from Enelife Battery Co., Ltd. It is still usable. I don't know the model name, but the extension pipe is marked "V10fluffy". There is a slight dent in the extension pipe. There is a crack in the third photo. It works, but I'm not sure if the crack affects suction, so please consider it for parts or as a spare. The wall-mount stand is missing screws.
