THIS IS A REPAIR SERVICE ONLY. We will ship out packaging with a prepaid return packaging. It's eBay's requirement. You must insert a note in the packaging or the receipt so that we can identify what belongs to who. Thank you so much for visiting. Ive accumulated thousands of original Apple parts over the years. Sadly I have to buy batteries overseas - and those aren't Apple Originals. There is a 6.7% chance that the battery will fail. So you have two choices. 1) Start a return, which is absolutely free for you. 2) send it back to me - with a note of what went awry, and I will send out a replacement and cover your costs of shipping.
We do make mistakes. Just message me with the issue and it will be taken care of quickly. Joe and Family
