I ordered the 4.8v 900mAh Ni-CD Battery and received the 4.8v 600mAh battery though all the paperwork and this review states I got the 900 mAh version. Frustrating but I'm keeping the batteries. I don't want to deal with returning because I have been waiting over a week to get a return label for some other batteries I need to return. I received the batteries fairly quickly though I had to pay for better shipping through UPS.
