ZipZap not working

[PittPenguinFan]

I found my old ZipZap, a red Dodge (Viper?), in my closet(I haven't used it in atleast a year) and decided to see if it still worked. I turned on the controller, the light was green, and then put on my car on to charge. When I did, the light blinked red about 30 times, then turned a yellowish color. I put in on my table, but it wouldn't move and the lights don't work. The car is on (that was the first thing I checked). I assume it's not the AAA batteries, because the light on the controller works. Is there something wrong with the car?
