Your best bet for monitoring battery health on your Mac is to get a free app that does so.

Since I was still in school at the time, that wasn’t nearly enough to get me through all my classes. My MacBook Air came with seven-hour battery life and at the time I replaced the battery, it was getting around three hours. Remember when you first bought your MacBook and you were easily getting eight or nine hours of usage if not more before having to charge it? Over only a few years battery life quickly gets chopped in half with heavy usage. The most prominent tell-tale sign of a waning battery is its battery life. It didn’t die on me, but the health got so poor that I thought it was time for a fresh one. I bought my current MacBook Air five years ago and already replaced the battery once at the Apple Store. While your MacBook, MacBook Pro or MacBook Air itself can last you several years before it’s time to get a new one, the battery might not make it the entire way through.
