For more than ten years, I've used a sealed lead-acid battery of 4 to 5
Ah capacity.  It's low-cost, not too heavy, not too big, and has it
has plenty of capacity for several days operation.  For a backup/reserve
supply, I use a ten-cell AA-pack with NiMH cells.  The SLA battery is
far less problematic and much more reliable than the NiMH pack.

Here's a page full of the SLA batteries similar to what I use:
