Computer shuts off when battery at 79%

Testo:

I just got a used Macbook Pro 13" 2011 and the battery checks out as okay, but I'm having a problem with the computer shutting down, on battery, when battery hits 79%. I have retested it after the first time, and it again shut down at exactly 79%.
 
It runs down normally from 100%, then suddenly shuts down.
 
I can't reboot without using power cable. When I boot up with power cable, the battery shows 79% full.
 
Coconut Battery shows:
 
Full Charge Capacity = 5062 mAh
 
Design Capacity = 5770 mAh
 
87.7%
 
Manufacture date in 2013
 
Cycle Count = 4
 
Battery status = Good
 
Battery temperature = 27.3 degrees C
 
Strange stuff:
 
1) The CYCLE COUNT is a bit strange. Only 4. Though it did go from 3, when the computer arrived, to 4 after my first charge.
 
2) The computer arrived with Sierra installed, but I had some problems with the battery. When I ran the battery down and the computer shut off, when I rebooted the battery icon was SERVICE BATTERY, and the Full Charge Capacity was down to 2300.
 
3) The battery is really SLOW to charge. I'm recharging now and it's taken 1 hour to go from 79% to 85%. It shows 3:30 until fully charged, from 85%.
3) The battery is really SLOW to charge. I'm recharging now and it's taken 1 hour to go from 79% to 85%. It shows 3:30 until fully charged, from 85%.
 
I have since installed El Capitan, and the battery reports are back to normal.
 
But I still have the shutdown problem.
