Maybe it's bigger on the inside.

The length/hight is 2 and 1/2 of AA battery if you put one battery on the top of another.

The width is about 3/4 of the length

of AA battery. It would accomodate 2 AA batteries if you put them side by side like matches in a matchbox.

Correct!!!

That's exactly how it's set-up.

I have it. Works great for extending the charge life to like 10 billion page turns, but takes a really really long time to charge the unit. I have not been patient enough yet to leave it on the time required to charge my 505. Works with the 500 too and it takes 4 AA's. You can also change heads on the thing so it can be used to charge other stuff like an annoying cell phone.

I am curious how long would it take to fully charge the reader and how many AAs you need to fully charge it.

I've only used it once; I had 2 bars and it took an hour for it to fully charge. I don't know how many more times I can use it before I drain the 4AA batteries.

This one should work in a similar way and can't get any smaller

I would add some Hybrio rechargeable batteries that can be stored charged

I use these AA for my mouse and AAA for my Mighty Bright double led light.

These batteries can stay charged for (supposedly) up to a year keeping a 70% of the charge. In fact, they are sold charged. They work perfect.

This is a way to make the battery charging cheaper. When you are not traveling, you can use the batteries for remotes, mouses, discmans (or is it discmen?), etc.

There's a more interesting question: What's the voltage output ?
4 non-rechargeable batteries make for 6 V, 4 rechargeable ones make for 4.8 V.
So if the voltage is 6 V, we know for more or less sure that the Reader withstands 6 V input voltage. If it's 4.8, we know we could use rechargeable batteries as a recharging power source.
If so, it'll be a breeze just getting hold of a 4-batteries holder and simply solder a piece of wire and a plug to it and we're done.
If voltage is regulated down to 5.2 Volts, we'll need a 5-batteries holder and a voltage regulator if we're into DIY.
Estimated costs of a DIY mobile charger/backup battery: 3 Euros plus batteries.
Drawback: Some effort.
Benefits: Flexibility and free choice of batteries, usability beyond the magical 1-year-till-dead-barrier of LiIon batteries, and the priceless "I-made-it-myself" feeling.

So it might be a great thing if you hook up your voltage meter and tell us the results.

I recommend the PowerMonkey. A rechargeable battery that charges everything, recharges from mains, pc, or solar. The solar also charges accessories directly. Comes with many tips, incl.mini-usb,PSP, regular usb socket, etc. It is sometimes on sale with a huge rebate.

The output voltage with the NI-MH battery is 4.8 to 5 volts.
It will charge the reader in 1 to 2 hours.

Nice simple DIY charger! I think regular AAs would be OK too, at slightly under 6V.
