Q: How do you know if a macbook battery retains less than 80 percent of its original capacity or more

My Macbook mid 2012  battery wears out in about 2 hours of use--and if I leave it sleeping overnight with 30%, it will be shut down with 0% left in the morning. How do you know if a macbook battery retains less than 80 percent of its original capacity or more? That is when Apple says they will replace the battery on Apple Protection Plan, which I bought.
