i'm sure the people in CS have lots of batteries for their DSLRs, video camcorders, nimh AA batteries for flash / digicam, etc etc...
How do you people keep up with charging all of your batteries?
Of course for those devices that are used daily, you charge them daily. E.g. Handphone... But what about for those devices that you use only once a while? How often would you remember to charge them?
Especially for those nimh batteries, you could have so many sets of 4. How to ensure all/most your batteries are charged?
