Accidentally unplugged your power cable without noticing and now your battery is dead?
Want to take care of your computer and maintain your battery life?
Love the assuring sound of your iPhone's chime when you plug it in?

Battery Charging Alert is just right for you! With the app, you can receive alerts for when your computer is plugged in or unplugged, and when your battery percentage reaches a preset level, so you know when to plug in your computer to keep it from dying or to unplug it and save your battery life.

- colorful battery icon and text on your status menu bar let you know the status of your battery with just a glance.
- real-time display of when the computer is plugged in or unplugged, battery percentage, and health, as well as warnings of critical states in colors.
- the same power charging chime sound effect you are familiar with on your iPhone, indicating when the battery is charging when the cable is unplugged, the battery is charged to your preset percentage, and the battery is drained to your preset warning percentage
- all settings can be adjusted by a slider or turned on/off individually 
- all alerts can be sent as system notifications to your Notification Center

Need some first time running tips?
The setting interface of Battery Charging Alert is self-explanatory.
Plugging in and unplugging your charging cable should allow you to hear the familiar chime sound effect when an iPhone is plugged in.
Battery life can be prolonged by charging the battery to a set high point and unplugging it to be drained to a set low point, and to keep the power percentage between this range. You may drag the slider to set this range.

Great job

This application is what I wanted! I always hated it when I was doing something in full screen, and I forget to check the battery, and then it dies on me. With this, I can finally know when it reaches 20% so I can plug it in and when it reaches 100%! Keep up the good work!

Very good battery app; could be the best if...

I'm always on the lookout for menu bar apps (menulings) with the smallest foot print. This app takes up even less menu bar real estate than the incumbent Battery Monitor which has unseated Apple's own underwhelming Battery menuling on my MBP. It also offers system Notifications when battery level falls below a definable threshold, which is a Must-have for battery apps, IMO. What makes this app less than perfect (and not quite ready to replace Battery Monitor yet) is the fact it doesn't report the Design Capacity and Current Capacity of the battery, like the latter does, hence my current four-star rating. Otherwise, it's a very good app for monitoring your current battery level, if you don't care about the capacity info. It has the potential to be the No. 1 battery menuling.
