Battery Log will monitor the batteries in your handheld and give you an estimated date for their replacement, based on actual usage of your handheld. Features:

• Collects and displays useful statistics for each set of batteries, like voltage and percentage of power remaining, the total time since you last installed a set (or started monitoring with Battery Log, whichever is later), the total time the handheld has been in use, the total time the backlight has been in use and the total time the handheld has been sleeping.
• Auto detects a change in batteries. You only have to have the monitoring component running and Battery Log will automatically detect when batteries are changed.
• Maintains a history of all batteries that have been monitored, so you can quickly see how different batteries have performed.
• User defined notes (up to 80 characters) for each battery set.
