Charging takes about 5 hours, so if I put them in the charger when I get home, they're ready in the morning. No big deal...
For the reasons you have stated, that is why I went with Cateye's Volt 300 Front Light with USB Recharge Kit, as it has a spare battery that you can recharge and take with you.
I also got their Rear Light, the Cateye Volt 50, as it shares the same battery as the Volt 300. So I always have plenty of options if one of those lights goes flat.
