Re:
I use the Primecell Scan Max SMX 4.8v battery pack designed for 250/296 and it works great with my 296d. When fully charged I get 13-15 hours in analog only mode. With the digi card enabled I get 8-10 hours. This is without the backlight, which I am sure eats a lot of power. They're at primecell.com, $19.95 and highly recommend.
