    Ahhh, a heckler in every crowd!

    But, I was mistaken about that weight - should have said 46 lbs instead of 26 (sorry!). And there is some wiring to be done.

    They tell me if your key-off electrical usage isn't too much, might could get away with one battery. 15 - 20 seconds of crank time, recharges in seconds. Guaranteed power even if batteries are dead, won't drain/need batteries on line to work; this is information from KBI.

    I would stay under 88 mph to be on the safe side! Sorry just could not help myself.

    Around 2 years ago I had thought about capacitors for starting system and I did a Google and found some outfit that actually made them for vehicles. I talked to guy at the company. They are expensive, around $2,000.

    He said they usually sell them to guys in the frozen north. They aren't affected by cold like lead acid batteries IIRC.

    Sounds like a great idea in place of the starting batteries. Then you should have a bank of batteries for hotel load. If you have a generator you can recharge the cap if you run it out.

    It would pay for its self in a year or so if I could replace three of my four 67 pound batteries with one 27 pound battery, one ultra capacitor 27 pounds one regular battery 67 pounds equals 94 pounds net savings 174 pounds.

    [/QUOTE]
    How would this pay for itself in a year?

    You lost me....... reliability issues with lead acid batteries? Net savings of 174 lbs? For? Expectations of said savings?

    If your merely looking to dump 2 batts off the set then recalculate CCA and buy 2 that match. Be a lot cheaper than the flux capacitor your looking at.........

    ? standing by.....

    Maxwell ultra capacitor cost $1,100 from local Volvo dealer
    Maxwell rep claimed real world weight of 27 pounds.
    Everything!!!! I haul is a per pound / ton rate, more weight = more money
    I stay old about one day a week so hotel load is a none issue for me

    the old saying of figures don't lie, but liars can figure

    It would take about 160,000 miles to pay it back at four cents a pound in a perfect world.

    Stay away from the capacitors unless YOU have the 1.21 gigawatts to power them. how long must I hold your hand, thru this learning process. :study:

    to see if anyone on this post is up to par with me... does any of you have an electrical engineering degree? :biggrin_25519:

    no but they should try 70.7 finals before paying $200 for a capacitor that they could make with cardboard tube from t-tissue and wax paper + aluminum foil.....

    This is the only good reason I have heard to use them

    Didn't realize a question to the intelligent o-o's, drivers, and technicians reading these posts would turn into some sort of urination competition of who's smarter!!! Thanks for reading and responding.

    Haven't gotten back with KBI yet, may still get their info; but not sure if it's right for me after some consideration.
