Rayovac IC3 batts
 

I just got some earlier today along with the 15min charger. The car seems quite a bit faster than with my silver and gold rayovac's. The charger is really nice, it has a fan that runs while it is charging. I guess it only does this when charging IC3 batts, and other rechargables take a fiew hours to charge. I highly recomend them.

Were did u get them from and how much did they cost?

walmart, $20 for the 2 bat charger or $28 for the 4, both chargers come with 2aa's. 4 aaa's were i think $14
