Some people have told me that you get more recharges out of the white batteries. They indicated the higher the mah, the less recharges. I swear by the white batteries. I once bought a set of Imedion rechargeable batteries with a mah of 2400. I bought the white Sanyo batteries at the same time. At present, the 2400 batteries won't hold a charge for as long as the white ones. Also, the Imedion batteries were very expensive.
