After living with the standard battery for a long time, I bought this battery and jumped from 15 minutes of batter life to 4.5 hours at least. Very cool! As mentioned before this battery tilts the laptop upwards which provides for better ventilation. Double cool!
I've had this battery for just a day, but I'm very happy with the performance so far. I run Vista Ultimate, so it demands a lot of power. Depending upon what I'm doing, I can get around 3 solid hours from this battery versus the one installed by HP which got around 2 or less.
I bought this battery to get my through my classses in university. It provides more than enough power, which allows me use it during my free time without having to worry about losing power.
I bought this to replace the original battery on a HP that lasted 13 months. It looks similar to original, fits properly and charges to 100%. I ran the computer from 100% charge until it shut down and got 2 hours 45 minutes run time. This seems about right for the capacity of this battery after the first week of use. I just hope that is lasts longer than the HP battery did.
