frustrated

I have two brand new Kr808d batteries. They are both not working. One gets so hot when on the charger that I think a fire will start. It blinks 3 times when put on the charger and then nothing....no light no light when trying to use it. The second one acts like it wants to work but produces no vapor. The light on the end comes on when I try but nothing. It blinks 3-10 times when put on the charger. These were delivered yesterday. I have other batteries that charge fine so it is not my chargers.....Any suggestions? I can send them back but man I needed them this weekend my others aren't holding a charge for more than 30 minutes or so. Thanks in advance!
