If done right they work well. I started out with rechargeables in 2001, started having problems a couple years later with them not holding a charge and started buying lithiums. I started reseraching and found out that I had a bad charger and then low self discharge batteries came on the market. So in early 2006 I went back to rechargeables with a real charger and low self discharge batteries and they work as well as or better than lithiums. The biggest problem with rechargeables are the batteries and chargers sold in most stores are crap, your lowes and home depot, radio shack, walmart and other stores are all poor chargers and the batteries are usually too high capacity.
