I have been playing with graphine ultracapacitors for a few years now after watching all of lasersaber's videos on YouTube. Turns out that for specific niche uses that ultracapacitor "batteries" are fantastic. I have a pair of 6 cell units that I put together using Maxwell boostcaps for one and Eaton for the other. They are 2.7v x 6 for the Maxwells and 2.85v x 6 for the Eaton. I have the Maxwell unit dedicated for use in my 6-71 Detroit powered International semi (it replaces the 2 12v lead acid batteries).
Imagine a "battery" with no electrolyte, that weighs 8 pounds, doesn't care what orientation it is mounted in, can drain completely and be left dead indefinitely or freeze without damage of any kind. It can be charged from dead to 16+ volts in under 2 minutes with a 200A charger. Has an estimated 7000 CCA which aren't effected by cold temperatures. It will crank an engine for 35-40 seconds with the ignition off before going dead. It cranks down to 9v or less where lead acid won't crank below 11.5-12v. It also operates at alternator voltage so instead of 12.7v of lead acid it stays at 14v of the charging system. It will operate in a 6v system happily with no modification, it just stays at the generator voltage of 8v.
Downsides? Costs about $300 to build. Doesn't have much reserve capacity, so parasitic drains will deplete it quickly. I run a battery cut-off in the semi and shut it off if it has to sit longer than a few hours. I put the Eaton unit in my Case SC (6v) for testing and it has been great so far. I have many tractors and other vehicles and I am sick replacing several hundreds of dollars in batteries yearly. I am also developing an in cab battery kill using a starter solenoid on the negative cable with a hot wire from the capacitor to a switch in the cab to energize the negative terminal.
Fascinating technology, it stores electricity as static electricity instead of chemical. I plan to just move the Eaton unit between vehicles. I also made a small unit for our lawnmower and generator. That one is the size of a softball. Should pay for themselves in no time.

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
