My last few Bosch 1/4" bits have lasted about 4 bathooks a piece (FA's on obscure NC cliffs). Does anyone have any suggestions regarding different brands, modifications, techniques, etc. to make the bit last longer?

i have found that as my battery gets older, the bits have a shorter life. i believe this is due to the battery having less of an ability/power to hammer, therefore the bit ends up doing more spinning, which wears it down faster.

What're you climbing? Basalt?
Try sandstone, bits last forever. (YOU won't but your bits will.)

Since you are talking Bat Hook Holes, you are probably hand drilling. There is no way that 4 half inch bat hook holes are making your bit dull. Are you talking about breaking the carbide tip of your bits ? If so, you are pounding too hard with your hammer while simultaneously twisting. This will break your tips really fast.
Try lots of "light fast taps" and lots of turning the drill. :)

I've not been real impressed with bosch's bits. They seem to last about 2 holes....
