This battery really extends the usability of my iPaq (5550). The downside, for me, was I thought this battery was the exact dimensions of the original. It's not. It's about 6mm thinker. Meaning it sticks out the back. So if the unit is sitting flat on a bench and you press the power-on button the whole thing rocks backs, unless you hold the thing down.

Also with this battery fitted you cannot slip on a compact flash sleeve or any other for that matter (unless the sleeve you have accepts an additional battery on it's back). So weigh up what you want to do have long battery life or be able to slip on accessories. It's one or the other. And remember when you change the battery you loose everything stored internally on the iPaq a real pain.

I still have an open mind about this product, but am not happy with its performance. I am a medical student going into residency and use my PDA all the time to look up drugs and confirm patient care...

The battery sticks out about 0.5 cm from the back of the PDA. No big deal. I remove the protector anyway to reduce volume and to not have to deal with cover in my hand. I was willing to put up with the bulky battery. I was looking forward to the extra battery life, but the product does not sit easily in the cradle (not an understatement). This is a problem in getting the device to sync and charge. I tried to charge the battery without the cradle and had no luck. The indicator light never comes on so you can not see if it is charging. Eventually the battery indicator on the PDA showed it was depolarizing. Something is wrong with at least the battery I purchased and I will be going back to the original one I have.
