late 2011 MBP shuts down when unplugged

hello, my late 2011 MBP (on 10.9.5) was just recently at apple, the logic board was replaced. soon after i got it back, it started to shut down when unplugged. re-booting works, but only for a minute. the system report has the following, does anything look out of line here? it seems like a battery issue, i'm on the original battery, but i figured battery wold just get shorter and shorter, not just cease working.
