I also am trying to lessen the logistical nightmare of battery types. I am finding it hard to do with infant/toddler toys but luckily they will grow and add a new challenge when the toys change. As far as the rest of my gear, the easiest thing for me is to think about multitasking different lights, etc.... to eliminate the challenge of stocking different batteries.

I have had good luck and great service from batterybob.com for all types of batteries. I'm just a happy customer, not involved with them at all.

Love the site, longtime lurker and first time poster.
