will a ssd in my laptop increase my batter life?

Yes, but only by minutes, not hours.

EDIT: Edited for clarity.

Yeah it may help a bit, but I wouldn't think very much. LCD backlight, CPU, and discrete GPU (if your lappy has one) are probably the biggest power users. Hard drive, RAM, etc. are all pretty small, on the order of a few watts each.
