A reminder: charge you NiMH batteries if you haven't used them in a while. NiMH batteries will loose their charge in storage rapidly so you need to pull them out periodically and top them off. I have 6 sets of four NiMH batteries around, mainly for use in my speedlite flashes. I have to remember to charge them once a month and before I need to use them.

Pictured is my La Crosse BC-900 NiMH charger (Amazon, $80) which has turned out to be the best battery charger evar. Selectable charge rates, discharge and refresh cycle (bring previously dead NiMH batteries back to life, really!).
