You should never need to remove the battery, other than to actually replace it.
A Hardware Reset will disconnect the battery briefly, so it accomplished the same thing as physically unplugging it.
Simply pushing the power button, or rebooting, does not remove the trickle charge that keeps the embedded controller (EC) running. A hard reset drops all power to the EC, so when the power comes back on it goes through a reinitialization. Since the EC controls the keyboard, touchpad, battery and all other on-board peripherals, performing this it can potentially fix a wide range of problems.
If the battery tests OK, then you have a bad charger, a bad charging cable, or a damaged charger port.
The procedure is detailed on this web page. Some devices require specific steps, but most newer devices only require a simple keyboard sequence.
First turn off your Chromebook completely (don't just close the lid).
Next, hold down the Refresh 
key and then press and hold the Power button. Hold both down for 10 seconds.

We have to figure out if you have a bad battery, or if something else is going on.
- Open a Crosh Shell (ctrl alt t)
- Type "battery_test" and wait 5 minutes for the test to complete and then copy/paste the output when you reply.
Many users cause their batteries to fail prematurely by allowing them to go completely dead before recharging.
Modern lithium batteries, like the one in your Chromebook, do not like being discharged completely. Each time that happens, damage is done, until it fails completely.
Also, they cannot be overcharged like old technology NiCad batteries. So, follow the approach that many of us experts take - keep your Chromebook plugged in all the time, unless you need to use it while mobile.

If the procedure to reset your hardware does not work, you may have a hardware failure.
First, move everything to another plug in your house, in a different room. If that doesn't work, does your charger light come on?
If you have access to a duplicate charger, try the other charger.
If that doesn't work, contact your manufacturer for a warranty claim or out of warranty service.

We have said, many times, that a battery_health below 80% indicates a failing battery that should be replaced.

I am a user just like you. I am not a Google employee or contractor. You are not my "customer".
I volunteer my time trying to help others wherever I can. I don't enjoy reading through countless "me too" posts, but I do.
What part of "you need a new battery" do you not understand? You have a very old Chromebook. It is impressive that the battery has lasted as long as it has.
Perhaps you should take your Chromebook to a repair shop and pay someone for that same advice.

I was addressing Britt L, not you.
This thread is close to 2 years old.
It is a thoroughly confusing mess with many users posting overlapping comments and then coming back many months later.
If you actually want personalized help, start a new issue thread of your own. There is a link on the Community homepage where you can Ask now - that starts a thread of your own. Please include the details of your issue, including screenshots, the make and model of your Chromebook, what you have already tried, and the version of ChromeOS that you are running.
