Use a #1;phillips head screwdriver.
I own an APC RN450M. A #2:phillips head screwdriver doesn't work with that 450 VA model. In fact it doesn't even fit in the screw holes.
But a #1;phliips head screwdriver with at least an 8 inch shaft woks fine.
Agreed with @bobhyman, a #1 Phillips screwdriver is what's needed, although something a little shorter than 8 inches is probably OK too (measure the height of the entire unit as an upper bound). It might not be super-easy to find one of these at a local hardware store, but I ended up ordering something on Amazon. Other than that this is a pretty easy replacement. Thanks!
I used a #2, but it was a skinny one.
The yellow battery shutoff clip is what gave me the most problem, it was really tight in there!
