Hi Terry, I'd suggest something like this: http://www.zapworld.com/recharge-it-all/m-48-laptop-battery At 06:08 PM 4/30/2008 -0400, you wrote: > So........... I just ordered 10 NiMH batteries to make up a 26.4 watt-hour (12V, 2.2 Ah) external battery pack for my PDA. The battery in the unit is only 4.4 watt-hours, so the external pack should last longer than my arm. I'm going to make it flat (about 3"x4"x1/2") and put a nice mark-free rubber pad on the bottom. The pack will serve as a base to set the PDA on so that I don't scratch a piano finish. I'll also try to rig up some sort of attachment method so I can mount the pack directly onto the PDA cradle so that when I want to use the tuning pin mount, I can move the pack and PDA as one unit. The pack will also have an LED voltage monitor so that I can always be aware of how much juice I have. This pack should have way more than enough power for a very full day - >/ Virus Database: 269.23.6/1407 - Release Date: 4/30/2008 11:35 AM Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.P.T.
