2 Why does my MacBook Pro say Service Battery?
I installed a replacement battery from iFIXIT several months back. It seemed to work fine until about a week ago. Since, I could only power up the device with MagSafe connected, despite the battery being completely charged (the indicator on MagSafe was green and indicator on device illuminated 8 of 8 dots).
Once the device is powered, the battery status page shows a cycle count of 37 and a full battery capacity of 63mAh. Unplugged, with full charge, the device lasts about 5 minutes.
What do I do?

lets get a better idea on what's happening here. Install this great app CoconutBattery. Take a snapshot of the main window so we can see things. Do tow snaps one with the MagSafe plugged in and a second after a good five minutes just on battery and post them both here Adding images to an existing question
You may want to inspect your MagSafe charger making sure its cable is not damaged in any way and the connector is in good shape as well. Review this Apple T/N Apple Portables: Troubleshooting MagSafe adapters

You said that your battery now has a max charge capacity of “63 mAh”. If I remember correctly, my iPod Nano has more than that. This means that something’s wrong with how the laptop is seeing the battery.
Try running it down to empty, leaving it for a bit, than charging back up.
