I'll be moving over to Kingston, Ontario, next month. Obviously I'll be building up a winter bike! My question is about lights, or more specifically about batteries, in winter...
I have a couple of sets of long-lasting NiMH and Li-Ion rechargeable batteries from my dark winter commutes (and marathon XC racing days) in the UK. I was thinking that these would do the job, but I have been told by some people that many such batteries will not work under certain temperatures.
So, will my rechargeables do? Or is rebuilding my front wheel with a hub dynamo the only solution? What are the working temperature ranges for different kinds of batteries?
