Comments about Canon Canon NB4-300 AA NiMH Rechargeable Battery Pack (4-pack):
I've used other rechargeable batteries in my Canon digital camera and none of them last like the Canon brand ones. The first set I had lasted me 2.5 years, and I used them heavily. On trips, I could take photos all day on one set of batteries. The other brands I've tried can't manage that.
