Try resetting the SMC, the Apple website will tell you how

Also look in About This Mac > More Info > Power

Does it say battery installed - Yes?
Under battery health it should say "normal" & a cycle count. What does yours say?
What does it say for Full Charge Capacity?

Almost certainly a bad battery.
Under battery health it should say "normal" if yours says "Check battery" that's a bad battery.

You have 1558 cycles, that's a really old, really tired battery. Apple says they will go for 1000 cycles.

Also your voltage and max capacity are very low. Bad battery.
