[QUOTE="spoonraker, post: 3139716, member: 570956"] Even a huge cap drains almost instantly. Well, maybe in about a second or so for a decent one, but that's still a drop in the bucket for a decently powerful system. What most people don't understand is that you don't completely drain a cap. The cap is only utilized until it's electrical potential is lower than the battery or alternator, not all the way until it's empty, that means that about 85% of the capacitors stored electricity is never used. I can't remember the exact numbers, but one time I did the math for a huge batcap...we're talking a large capacitor bank that would dwarf any capacitor you can buy. It was boasting an impressive 8 second discharge time at up to 400 amperes. Now even this beast of a capacitor will drop below battery voltage in just over a second, how are you going to tell me that a single 10 farad cap is going to do anything useful? [/QUOTE]
