1800 mAh and 3600 mAh battery for 4155

[kente777]

Now that I'm using the WiFi feature on my 4155, I'm going to want to upgrade my battery. The 1800 mAh battery looks to be twice the thickness of the standard 1000 mAh battery. HP shopping folks told me that the back plastic plate should have no problem snapping back on once the battery is placed in its slot. Frankly, I can see no way that this is going to work. Does anyone know if a different back plate is made for this battery?

Also, has anyone seen or used the 3600 mAh battery. This looks to snap onto the entire back of either the 2200 or 4155 series? Does this really work on both units even though there is a size difference to the units?

I hope I made sense. Thanks.

I believe that the 1800 mAh battery incorporates its own plastic plate onto the battery itself. As for the 3600, I'm told that the battery only supports the 4155, not the 2200.

The 1800 mAh product comes with a larger battery cover to accommodate the larger battery. The resulting bulge is about half the thickness of the iPaq.

The 3600 mAh product is not compatible with the h4100 - the battery will only fit the h2200. It's an error on HPShopping.com.
