FruitJuice - Active Battery Health and Monitoring

By The Battery Project, LLC

Open the Mac App Store to buy and download apps.


FruitJuice helps you achieve the longest runtime and lifespan from your Apple notebook battery.

FruitJuice will let you know how long to stay "on battery" each day to keep your battery healthy based on Apple's recommendations. *

FruitJuice keeps a detailed record of your battery charge and discharge activity so that it can make precise recommendations about how long to use your machine on battery based on Apple's recommended usage patterns.

Recommendations are tailored to your specific usage patterns and are adjusted in real-time based on how you actually use your machine.

Flexible configuration allows you to see as much or as little information as you wish.

Notifications will let you know when to plug in or unplug your machine to keep your battery healthy and avoid the surprise of "You are now running on reserve battery power."

FruitJuice also will show you a realistic assessment of the overall condition of your battery: it combines the battery condition, age, factory capacity and lifespan numbers to give you real-time insight into the health of your battery.

Great program - well worth the price

I'm on my third Apple laptop and have typically had problems with batteries in my laptop computers. Over the years, I have become more battery savvy but, until recently, still have had issues with battery life not being what it should. I found this app when I installed a new battery in my 2008 MacBook Pro about a year and a half ago. Having this app has made a world of difference. After 113 battery cycles I still have nearly 98% of the original capacity of my battery. Comparing my battery performance to others via Coconut Battery Online reveals that my battery is performing much better than expected at this point in its life. The gentle reminders provided by this app help to ensure that I am using my battery properly. It’s become something that I rely on to ensure that my computer is working properly. Highly recommended!

An essential and excellent app!

I am using this app on an old MacBook Pro (13-inch, Mid 2009) after replacing the battery once and this app has certainly helped to regain some battery health (from 94 % to back 96 %). I wish I had found this app a lot sooner. This app is probably the first thing one should install after getting a new Mac Laptop for optimal battery health.

Useful, unobtrusive, responsive

It’s useful: I’d otherwise have no idea what balance of charge/discharge keeps the battery happy. It’s unobtrusive: starts automatically, uses a tiny amount of menu bar space, lets me customize alerts. Responsive: I filed a bug report and got a speedy and helpful reply.
