Hi, so yesterday the battery of my old MBA (Original 1,1) which I rarely use bulge badly. I took it to the apple store today to see if maybe it was a lucky day and I got a free battery - no luck. The genius reminded me about the Apple Reuse program, so I got some quotes on how much they would pay me for it: with a working battery ~190 and with a bad battery ~100. A new OEM battery costs over 100 so it makes no sense to buy one. However, there are 3rd party ones on ebay going for about 37. Does anyone know if I send the MBA with a 3rd party battery if I will be penalized in the offer? Thanks.
