Let's backup here a bit. The issue is the system shutting down when the power is low without notification. This is where the SMC services stores the battery status. Did you try resetting it as well as cycle your battery a few times so the value within SMC was correct?

First download this great little app: coconutBattery. Here's a bit more: How to diagnose MacBook battery problems, and replace a MacBook battery

Then follow this Apple T/N: Resetting the System Management Controller (SMC) on your Mac.

A new battery could be bad. ???


Yes, they can be over charged, over heat, on and on. I hate replacement baterys because the device will work like gold, then the batery goes. You replace the batery and your device acts up or dies. Happens every time for me. I only get and use exact matches for batery replacement and still i end up buying a new device.
