The battery I have is a Yuasa NPC24-12 12 volt 24 AH lead-acid
battery, which I think lasts for about 24 hours with my laptop (Sony
VAIO pcg505fx). It is very heavy. You may be able to get lighter
batteries, but they will be more expensive.

I haven't noticed this, maybe the UART uses more power when in
use. You can save power by switching the screen off if possible, and
by letting the harddisk spin down when not in use.
