evolta battery world record train run

[Super]

I have not tried this battery but i do use Sanyo's Eneloop rechargeable batteries. Also purchased a 16 battery charger and double AA conversion case for C batteries. So all of my locomotives now run on just AA batteries.

I use these "C" to "AA" conversion cases also but it does not fit in all trains. What do yours look like? I have over 200 AA Energizer Lithium Ultimate batteries that I got very cheap and also try to use "AA"s to replace the "C" batteries. For some reason some of the trains run better on the AA than the C but I don't know why. My battery charger unit charges all batteries, 9volt AA, AAA, D, C. Ni-Cd, Ni-Mh and Alkaline...yes, the charger I have has a switch for recharging Alkalines. They say an Alkaline can be charged up no more than 10 times. It does work so I have been getting extra life from my batteries.
