Battery Monitor is a simple application that records the performance of your battery over a discharge cycle by writing the power and estimated remaining time to a text file every minute. You can then use this list of values to see if it works as it should. (E.g., does it discharge fully or does it break down prematurely?)

Note that this tool does nothing magical. It simply records to a file what you can see when you use a stop watch and look at the battery indicator in the control strip or menu bar.

Since the values of every minute get recorded, you can use the output also to iport into a spreadsheet for making nice graphs. Its up to you to figure out how to do that.

BatteryInfo is a Dashboard widget designed to be a better looking, dashboard based replacement for the menu bar battery monitor. Thanks go to Luis Moreno for the graphics and to Marc Wolfgram for helping implement dual battery support.
It has the ability to display the percentage charge remaining. It can also display the time remaining on current charge, although this feature is somewhat ugly and needs beautifying, so if anyone has any suggestions for making it look better, mail me! It also fully supports dual-battery setups in Pismo laptops. If you have any comments, queries or suggestions, mail me at widgets@menial.co.uk.
This widget is more accurate than other copies out there are it pulls its information from the same place as the Apple menubar item. It also looks nicer IMO ;)
This widget is freeware, although donations to keep me in bandwidth are much appreciated. You can do this through the widget homepage.
