This is certainly possible to do. I believe its even possible to "jump-start" it (since you're not cranking the engine) with 8 D-cells in series.

If I were in your situation, I'd look to see if I could find a riding mower battery. They are flooded lead acid, and are usually closer to $25. But at this time of year, you may not find any
The low end car batteries I can find are more like $80-100+tx (which is 13% here). A riding mower battery *might* work.

Probably easier to obtain this time of year up north.
A snowmobile battery might just be the ticket. Good idea. I'll research those.
