I use Fenix flashlights (2) on my commute, and two Planet Bike SuperFlashes as well. I'm also using a no-name flashlight on strobe mode -- it runs on three AAA batteries.
So I'm using four AA flashlights, that need to be recharged every other day, and four AAA batteries, that need a zap about every three weeks or a month, sometimes longer, and three batteries that need help about every week.
I'm using a charger that came with a set of AA batteries -- can't remember the brand, but got it at Lowe's or Target or somewhere.
Is there a better battery charger that I could use, or does it not matter?
