Thank you for viewing. This is a new, unused replacement battery for the Apple iPod Classic. It is labeled as 30GB, 3.7V 650mAh, but it can be used for all models from the 5th generation up to 160GB. If you need an additional one, it can be included for an extra 900 yen. If you prefer Mercari delivery, it can be changed for an extra 100 yen, so please let me know. I once received a return due to a reported malfunction, but I confirmed that it was perfectly normal and has already been discounted and resold without any problems. I apologize, but if it doesn't work properly, please clean both contact points and make sure it is securely installed. When opening the body, it's difficult to open with a resin tool, so a thin scraper, which is also sold at 100-yen shops, is easier to use. Also, I apologize, but as stated in my profile, there have been no postal accidents so far. However, postal services currently do not deliver on weekends and holidays. If you are in a hurry or need various guarantees, you will need to pay an additional fee to change to Mercari delivery. If you do not change, various guarantees cannot be provided, so please understand. #iPod iPodClassic #iPodClassic #Apple Apple #Music player Music player #iPodClassic #iPod #Apple Apple #Apple replacement battery #ipodclassic #replacement battery
