Is it slum to have 2 batteries instead of one cap. I don't have a cap, but two batteries, i put an extra battery in the trunk. I put it in a box with vents and sealed it; i ran tubes out the box and out vents in the trunk so the corrision and acid wont destroy my equipment. Should i still get a cap?
Croucher, why why why would you put vents in your trunk?? Haven't you heard of sealed yellowtop batteries? No acid to spill and gases to worry about. Look for a similar topic in amps and accessories. Your question was already answered. I'm sure you'll find it interesting.
