Hey, guys. I have a couple of questions regarding batteries and charging. Bear in mind the questions I'm asking is for a toy grade RC:

1) I have a 600 mAh battery that's getting me roughly 13 minutes run time. If I upgrade to a 1600 mAh battery, barring the added weight because of the higher capacity, and I run the vehicle the same way as I did before would that theoretically multiply my run time by 2.66 times? If not, about how much more run time would I be getting?

2) The charger I am currently using has an output of 12V DC 350mA. About how long would it take to fully charge the 1600 mAh battery and how long should I keep it on the charger for the initial charge?

I'm sorry if these are stupid questions but I am totally new to this hobby and all this is a learning experience for me. Thanks for any help I can get.
