You may not need to charge it, just bringing it into the office will warm it up so it'll have more power available when you start home.


In the normal course of things, I replaced several of my extra blinkies this year. It's getting harder to find decent lights that at least pretend to be weather resistant, so I've got at least one rechargeable blinkie on each commuting bike. I've already found it more of a hassle to take each one off the bike, bring it in, and recharge it weekly, as opposed to tossing a couple new alkalines in every 4-6 weeks. Not looking forward to finding out what really cold weather is going to do to the rechargeables.


Of course, my primary dyno lights just keep going, and going, and going...
