Increase short battery life!
 

Well this is my first post so... (where was I going with this?) oh well.

If you have a zip zap SE and your battery life is really short (4-15 seconds) You may not have to buy a new battery! (unless you want another one)
Step one: Open up the car
Step 2: Take out the battery and remove any hair or other things in it and the battery compartment
Step three: Sand the tips of the battery compartment (the metal) and the tips of the battery (the metal again) with sand paper or a nail file. why? so the battery can make a good connection.
Step 4: Put the car back together!
Step 5: enjoy your car!

And that's how to do it! (this is not guarenteed to work because there may be something else wrong with the battery)
w00t post numero 1!

Soldering leads to the terminals on the car and the terminals on the battery would likely work even better.
