Acer Aspire R5-471T Battery swollen (thickness). Is it caused by keeping it plugged in?

My Acer laptop's battery has seemed to have swollen in thickness over time, putting pressure on the laptop's case (bulge). I took the back off and removed the battery, and replaced the keyboard (a few bad keys). (Note I usually leave the charging cord connected, thinking there was something regulating the need for charge, etc)

Is this bulge a normal thing with this Acer? Or was it caused by leaving it plugged in?

Will the battery go back to normal size unplugged, or do I need a new one? Laptop seemed to work on battery only just before opening the case.

If replacing, is there a suggested battery, or possibly a thin version of the battery?

Online dimensions show replacement batteries to be just under 1 inch thick (.932)
