All machines (and i am assuming you mean the motherboard battery) eventually die. As far as i know, AMI no longer holds tournaments. Btw, the battery is the least of your worries. If the Hard drive goes, you have a really expensive paperweight. To my knowledge, nobody has even a working backup of a ml2 had drive. Even the company AMI, before they completely stopped supporting megatouch did not have a backup ml2 image/drive.
