This is an original Apple battery for a 2008 white 13" MacBook (this is *not* for an aluminum MacBook Pro 13). The battery was a spare and used only a few times (at max, 3 times). The Model number is A1185 and it is a 10.8V 55Wh Please note that the protective laminate is still attached / was never removed and it is this layer that is dirty/ yellowish. The actual battery is still pristine white (see pict with me pulling back the laminate). FYI, the picture of the Battery health info was taken last time I plugged it into the MacBook using iStat Pro.
