Battery for HP iPaq H5100, H5400, H5450, H5455, H5500, H5550, H5555 (1400 mAh)

This fits perfectly into my HP iPaq H5550, doesn't stick out or anything. It gets okay battery-life, maybe 1.5 to 2 hours use on a single charge; about 2 days standby. If I'm using it, I usually just keep in plugged in, and if I don't have that option, I put my iPaq on the power-saving mode.

Good battery life as long as you don't get too happy with wireless and bluetooth. I don't bother with a smart phone and paper organizers are bulky so I still use this pda every day.

Good hard to find product

It's cheap. But, it doesn't fit good. It's protruded, and I have to use tape to hold it down.However, holds the charge good.
