You can have the cursor text's color and transparency level change, depending on the power level. For example, you can set the program to keep the text transparent in cases when your laptop is connected to a power source, but visible if the portable is unplugged and below a certain power level. BattCursor has a lot of extras, too, such as ways to improve your notebook's battery life.

BatteryBar

Want to check battery life, but don't like the idea of having your mouse pointer display the text? Here's another alternative. BatteryBar shows, on your taskbar, exactly how much juice you've already used and how much you have left. You can set the app to display remaining battery life either as a percentage or as an amount of time.

Hover your mouse over BatteryBar, and you'll see even more information, including the total battery capacity, the discharge rate, the battery wear, and how much total capacity your battery has in terms of time per full charge.
