HiBattery measures your voltage level on every switch off (saving it into a Database) to evaluate a foreseen battery last time. It is divided in two programs an hack that build the database and the graphical presentation program, that display data and calculate expected last time. Vertical lines are days and week. Update Description:
v1.2.0 - 12/29/2001:
Added: now it is possible to consider only last "x" days in computation.
This add some flexibility if you use your palm after some time but you know that you want to use it for the next week and you want to not consider the period of time that your palm was "sleeping".
