If there’s one thing we MacBook owners know, it’s that batteries, and battery power, don’t last forever. Your Mac notebook won’t tell you much about the state if its battery, either.
The Menubar displays the amount of battery power remaining, and not much more. Either as percentage or time, and my experience is that it’s never been all that accurate.
Battery Health is a free Mac app that digs a little deeper than the Menubar battery indicator and delivers much more information.
All the basic information is there, including the current maximum charge capability of the battery (use it to see if you may need a replacement battery) vs. the original charge capacity.
It also displays power usage, the total number of times the batter has been charged, and other basics like how much music or movies or web browsing you can do before the battery is depleted.
Battery Health doesn’t do much to improve your battery, though.
Most of the same information is available with Battery Inspector, which comes with a 99-cent price tag.
The extra coin gets you extras, including battery serial number, temperature, manufacturer and manufacturing date.
Both apps inspect and check on a battery’s health and current condition, but neither do anything to improve battery life for a weakened battery.
