Still, when I had one, I would buy 2 or 3 of the packs every time I ran out, because I only made it through maybe 3 rainy days before having to throw out a holder.
Interesting. My experience has been mostly the opposite. Yes, the batteries and holder get wet, but I have yet to throw out a holder. I've been using my 140R roughly 50 miles/week since Oct. 2007 (commuting 2x per week plus one other day of riding, year around, in the rainy Pacific Northwest). From Oct 2007 to Dec. 2009 I also used a DiNotte 200L front light. That's two battery holders exposed for over two years. Overall, I'd say nearly half of my ride time is in the rain or wet, and I've never had a AA holder fail on me. I wonder why the difference....
