What's the best battery checking utility?

What a good reliable and accurate battery checking utility? can you find out exact details like what the current drain is on the battery etc?

 

Unfortunately other than RMClock, Mobile Meter and a few others(BatteryMon- $24/free trial) there arent accurate battery checking/information utilities out there.

For warranty purposes though HP Battery Check is what I would suggest. It will tell you the basic health of the battery and if your battery is qualified to be replaced under the warranty or not.

 

Personally, I use Mobile Meter It's small and free, comes in a single executable you can either download and run anywhere, or you can just open it straight off the website. It has a simple interface that shows you graphs of your current battery drain, as well as your CPU frequency, and temperatures. If you right click on its interface and choose Options, you can look at your battery information, which includes the current wear level, the battery's original maximum capacity, its current capacity, and how much charge it has at the time. Some batteries will also give additional information. I usually recommend it to customers, but I know there are lots of others that people swear by. That's just my personal choice.

 

I downloaded and installed Mobile Meter and an error pops up when i try to run it that says it failed to communicate with the ACPI dr..... why is that? i am currently running windows vista on an hp dv6424ca

P.S. thanks for the quick replies earlier.

 

Pretty much every utility out there gets the information from the same place. Everything beyond that is just additions the program made, or changes to how they're interpreting the data.

 

Unfortunately, MobMeter won't run under Vista. According to this thread: http://forum.notebookreview.com/showthread.php?p=2146684 it's because it needs admin rights and compatibility mode can't emulate that properly. Sorry my suggestion fails you in this instance. Perhaps you can try one of the others mentioned above.
