iFixIt disassembled the new 17-inch MacBook Pro and found out that the battery is actually removable. While it requires bottom chassis access, the battery was not difficult to replace or remove. Apple secured the battery with three tri-wing battery inside the case. Users can definitely replace the battery by themselves but it might break Apple’s warranty. iFixIt plans to sell replacement battery for the 17-inch Unibody MacBook Pro, which usually is cheaper than Apple’s $180 battery replacement program.
