Why do you need battery life for development? Most of the time you'd probably be in the office anyway.
Even so, ThinkPads have pretty good battery life, and on some models the CD drive can be replace with an extra battery. I've heard of some that can go nearly two working days before recharging.
I don't work at the office most of the time. I know thinkpads have good battery life generally, but I know there have been some battery life issues with linux in the past.
