I have put together a pack using 4 AAA NiMh cells and that works, I could not fit 4 AA cells into the battery pack shell. I also run my 97 from a pack I hacked together from a single cell Lithium "Power pack". The power pack is of the type that turns on the 5V when a load is presented and turns of again automatically when the load is taken away. To charge it I retained the micro USB connector that was provided for that purpose, so charging is convenient. I have also used it successfully in a HP-IL printer. These are things I hacked together, I don't know of anyone who is offering anything like this for sale.

I considered the possibility of using AAs, since NiMHs would easily give you as much capacity as the old sub-C NiCds. Flat-top AAs are readily available at Batteries Plus - I have a few for my 25, and my charger has enough of a "bump" at the positive end that it makes contact just fine. I've also got a few 4/5 A cells laying around that would likely work.

But I'd still have to build a holder of some sort, and I'm not much of a handicrafter. I'd probably have to jigsaw something ugly out of a block of wood and fine tune it with the drill and Dremel.
