Blinking amber light on charger...

Had the blinking light on my charger that I’ve seen several other mac owners went through. My situation is I have to keep disconnecting my battery to get it to come back on. It’s happening maybe 1-2 times every couple of weeks. Today I had to do it twice in a matter of a like 5 minutes. Would this obviously be a “faulty battery &/or charger” or is there potential for something more serious going on here? Grant it, every time I go through the process, the computer powers up, whatever charge I had before it went down, it goes right back to that same charge, and everything works fine. However, sometimes I can charge it to 100%, shut it down, or put it in sleep mode, & it will go to the blinking light whenever I try to resume use. What else could this be besides a bad charger or battery, or both?

Says the battery is good, so what could keep causing me to have to unplug the battery over and over.
