Eneloops or Powerex imedions. Charge and they will have 80% charge if left on the shelf for 12 months. Regular cells lose their charge in a month.

I used them in my old K100D Super, and use them for all my AA needs (eg. flash, P&S etc.).

Also get a Maha Powerex MH-C9000 WizardOne Battery Charger & Analyzer !! Best value for your cells. Never need another charger and can resurrect dead cells!
