Monitor the Juice in Your Mighty Mouse and Wireless Keyboard with MightyMonitor

Every once in a while, the Bluetooth icon in my Mac’s toolbar flashes the low battery icon, and I have to stop for a minute to check into what’s low on power. A widget called Mighty Monitor will help you pre-empt this situation, according to The Unofficial Apple Weblog.

Mighty Monitor is a widget that, once added to the Mac OS X Dashboard, will monitor the battery health of your Mighty Mouse and Apple wireless keyboard. By keeping an eye on the Mighty Monitor every once in a while, you’ll be able to have fresh batteries waiting for your peripherals, instead of being caught off-guard and having to make a run for AA’s to the corner bodega at the last minute.
