Photoflash cap specs

I've been posting on the Beginners Handbook thread and remain very much a beginner, but now I want to add a cap discharge system so I can use my SG to rejuvenate car batteries - so here I am.

I couldn't find a photoflash type cap here in Costa Rica so I'll be ordering from the states and want to make sure I get it right.

Peter says photoflash caps are best but doesn't give details about ideal voltage or uF ranges. Though he shows an "example" cap of 15,000 uF and 80V, if I disconnect an output wire to my charge battery the neons come on, indicating the radiant spike is always over 100v so it seems like an 80v cap wouldn't be enough.

Any advice on the specs I should be looking for, and whether to get one or more caps?

Also, I'm thinking a simple cam activated switch is probably the easiest to start with, and I found these super cheap ones on Amazon - https://www.amazon.com/SODIAL-Micro-...eywords=roller
Any feedback about whether they'll work?

Thanks.
