I have finally found a compatible battery on ebay. Here's the link if anyone else is interested: http://www.ebay.com/itm/111850527802?_tr... I've ordered the new battery and waiting for the shipment to arrive. Will update this thread once I get it. UPDATE: the battery has arrived and it fits perfectly... check out the picture bellow! And since it has a higher capacity than the original one, it lasts even longer before I need to charge it again. By the way the charging works normally without having to solder the blue wire to the black one. So I'm very happy that I've ordered this battery.
