Flakey Battery

This battery has been on and off flakey. It would simply jump to low power reporting, leaving my laptop to power off without hibernation. It's inital battery life was OK, but less than a year later with daily use it is very noticably degraded. I contacted customer support, but they were not very helpfull. They offered to send a RMA, but never did and I just haven't felt like pursuing it.
