Imtec Battery Mark
Full user review
"Find out how much life your laptop battery REALLY has!"
Held CPU at %100 and the fans for the system were on throughout the test. Nice graph of power discharge crossed with time. Did not try to sneak in any toolbars or extra stuff during install.
Did not disable power saving for monitor, so I had to hit the mouse every 10 min.
I just wanted to test several batteries in the same laptop- and was expecting to just charge them fully then watch the time as they ran down. This program gives you a graph with a timer and keeps the CPU load at %100 so you can watch that battery drain.
Ran great on an HP Dv6000 with XPSP3. Test takes as much time as it takes for the laptop battery to run out but now I know, really know how much juice the battery has.
Would be nice if it AUTO SET Windows to act like the laptop was on FULL POWER with no screen shut off etc. One star removed, even though it is FREE with no 'install google toolbar?' or 'install ask.com' carp during setup.
