The battery profiler displays the amount of charge in your laptop battery as it charges or discharges.

A good battery will smoothly charge or discharge through the entire battery capacity. A bad battery will charge for a while, then suddenly appear charged. When discharging, it suddenly runs out of energy as shown on the yellow plot in the display below.

Here are some key features of "Battery Profiler":

· Plot and print battery charge and discharge characteristics.
· Keep-Awake support prevents hibernation while profiling
· System tray support to minimize task bar clutter
· Displays total and remaining battery life (if supported by your computer)
· Time and charge percentage cursors help predict how long you battery will last
· Test new, used, or refurbished batteries to ensure they're not duds.
