ok, so according to spyder the battery will get about a 6 hour battery life. is this true? also (since it has to be charged in the gun) what can i do once the battery dies? can a normal 9v be used, or must i get a second spyder battery? also anyone know how fast the rapid charger (car charger) charges (approximate)?
That six hours sounds about right, yes you can use disposable 9v, or buy a new Java charger and battery if you want to (or any chargeable 9v will do). The car charger will be as fast as the normal charger.
with a couple mods you can also hook-up an RC Car battery that lasts a couple days. The Java 9.6V is 170 mAh if I'm not mistaken, and a 9.6v RC Car battery can hold many more mAh.
I have my mod posted somewhere here... I'll link it eventually...
