Hello, A quick question: Is it possible that a replica A1281 Macbook Pro (Late 2008) battery would cause the 85W adapter to fail? I bought this one: http://www.7dayshop.com/batteries-a...mb772-mb772-a-mb772j-a-mb772ll-a-4600mah-lp12 The first battery I received didn't work at all so I sent it back for a replacement. Second battery worked fine, however after 2 cycles the 85W adapter failed (no frayed wires, sparks or evidence of broken wires inside the casing). I just got back from Apple with a replacement adapter and all is fine now, but I have gone back to using the original Apple A1281 battery just in case. A bit reluctant to try the replica 7dayshop battery for fear of breaking another adapter! Any advice please? Worth noting that the replica worked perfectly - no overheating, long battery life and appears to be well made.
