Battery Mod For Sl-6000l Model, What do you electronics experts think? Options

I have both a 6000L and C1000 Zaurus, and was checking the battery output with a multimeter. Both batteries seem to have the same 3.7 volt output. Both batteries have 3 contacts, and voltage between the outside contacts are the same. And there is no voltage between the middle contact and either side (probably the middle contact is for charging [?] the battery). So I was thinking about fabricating a battery case that fits the 6000's battery compartment (except it will stick out about a 1/4" from the back to accomodate the thicker battery in the C1000). Then I propose to make some copper or brass contacts that are soldered to wires and to contacts on the other end. Then put the EA-BL08 battery in this box, with the contacts polarity matched up properly, and see if the 6000 can use the C1000's battery.

If it can, then I will have a 2000 mAh battery in the 6000 instead of a 1500 mAh battery. Also EA-BL08 batteries can be purchased much more cheaply than EA-BL09s.

The only thing I am not sure about is that the EA-BL09 says it is lithium polymer at the top, and lithium ion at the bottom of the same battery. (Not sure how it can be both?) The EA-BL08 is just labeled lithium ion.

Those of you who know about electronics see any obvious flaws with this plan? This shouldn't blow up my Zaurus should it?

[attachment=5496:C1000_ba...y_in_box.jpg] I already have an external battery extender. It is my hope to make an internal battery. So my question is whether or not the C1000 battery is enough like the 6000's battery to be used with a home-made adapter. I'm hoping that since they are the same voltage, and same number of contacts, that they are compatible (other than being shaped different).

I started this about 2 years ago, originally thinking to put a battery holder with 3 NiMH 1.2 volt AA batteries in the battery holder and putting the make-shift battery adapter in the back of the Z instead of the battery that came with it. The problem with this was that I would have to remove the batteries to recharge them.

So my latest brilliant idea (?) was to use the C1000 battery in my battery box. Maybe it is easier to see what I intend with pictures:
