MacBook Pro battery charged to 95-99%

Hello I charge my MacBook Pro battery last night, while it was turned off, I woke up the next morning and the magsafe light was green. I turned the computer on and the battery said 99% and charged. Is this normal, is something wrong? PLEASE HELP

It is normal and is done to prevent the battery from overcharging.

It's completely normal.

The battery starts charging only when it's at 94% or less, in order (I guess) to avoid putting excessive wear on the battery by constantly charging (as the battery self-discharges like all other batteries).
