Almost always I have my MacBook plugged to preserve battery health. But sometimes I forget to plug the adaptor or the wall outlet is switched off by others.
How can I have the MacBook warn me when it's running in battery mode?

How can I have the MacBook warn me when it's running in battery mode?
Here are a few possibilities:
- Power cable connected/disconnected alerts
Open Terminal and run the following command.
defaults write com.apple.PowerChime ChimeOnAllHardware -bool true; open /System/Library/CoreServices/PowerChime.app &Connect, or disconnect the power cable from your Mac and you will hear an audio alert. There will be no visual/desktop alert telling you what the sound means.
(Emphasis mine)

- UnPlugged Application
UnPlugged is an application that notifies you when the power cord of the MacBook is unplugged or plugged back in. It also notifies you in regular steps about your batteries capacity while you run on battery or while you charge your battery.
Notifications are done using the Notification Center, Growl or with a built in notification window.
UnPlugged stays completely invisible while monitoring your power plug. Only a small Menu Item is visible, showing the current battery status.
(Emphasis mine)
It costs $5.99.

- Juice Application
Use Juice! to keep an eye on your MacBook’s battery charge level. It can let you know when it’s time to plug in or when it’s OK to disconnect from the mains. Set it to warn you when you’re running low on battery or when the power supply to your laptop is interrupted.
(Emphasis mine)
It costs £2.99 / 3,49€

Disclaimer: I don't own a MacBook so I've not tested any of these possibilities.
