Currently, my laptop's shitty 1.7ghz celeron runs at 1.7v. I'm contemplating upgrading to a p4 northwood for the obvious cache reasons, but would I also notice any difference in battery life, seeing as they run at 1.3? Or is a difference of .4v too negligible?

Assuming your laptop uses the same socket (478) as the P4 Northwood, and is fully compatible with your choice of replacement processor (you have checked that, right? Some Celerons use a different socket altogether), the core voltage is irrelevant. It's the power consumption that's the all-important factor; ie. the wattage of the processor. The P4 consumes more power than the Celeron, so you will probably notice a drop in battery life. You also have to consider the amount of heat produced; the more power a CPU consumes, the more heat it produces. If your laptop's cooling system can't cope with it, you're asking for trouble.

My laptop can handle up to a 2.2ghz p4 and uses the same socket, so that's not a problem. Willamette celerons are just downgraded pentiums from what I understand, so asuming this holds over for Northwoods woudn't wattage be the same?

New Question: I did some more research and found out my laptop is actually using a desktop celeron as opposed to a mobile! The normal celeron has a lower thermal spec than the mobile, but should I still be concerned over this?
