Since digital cameras tend to absorb a lot of juice depending on how much photo and video shooting you're doing, I looked into saving myself some money on buying batteries. I decided on Energizer rechargeables because they seemed to be very economical and good for the environment (since I don't have to throw them away). The Energizer charger came with two AA and two AAA batteries, so I've already saved a little bit of cash there and I can recharge them up to 1000 times, so that's a lot of money back in my pockets. It takes about seven hours to get a full charge, so if you plug them in before you go to bed, they will be all ready when you wake up. The charger is simple to use: just slide the AA batteries in or flip down the adapter for AAA and plug it into any standard outlet to replenish your batteries. There is a readout that shows the progress of the charge and lets you know when they're finished. If you want to save money on buying batteries every few weeks, I'd highly recommend purchasing the Energizer Battery charger.
