Electric supply options

[motoretro]

I'm starting to work on my 1960's German scooter and in order to see if it will fire or not, I need either a new battery or some sort of electrical supply to help test the various apparatus. I really don't want to go buy a new 6V battery that might end sitting for a while once true restoration starts, Can I use a low (1 Amp) 6/12V trickle charger to run some power through the wiring, switches, starter, etc to determine what works and what doesn't?

Thanks, Motoretro
