MacBook air immediately shuts down when power is unplugged

My Macbook air immediately shuts down when the power is unplugged, sometimes (much less often) it will last 10-12 seconds after unplugged before shutting down. I recently had the battery replaced 4 months ago. When the battery was replaced it would initially go for hours on a full charge. About 2 months ago it started having this problem of turning off immediately when unplugged.
So far I have
* Reset the SMC
* Reset the PRAM
My battery shows as 100% charged.
I described both my coconut battery results and information from my system report below. It is strange that coconut battery shows at 100% and by charger light is green but, with the charger plugged in, my system report shows it is not charging and is not fully charged.
I can't figure out how to paste in images of my system report or coconut battery, but if there is a way please let me know.
