Ultracapacitors, Are they worth it?,...

[uncleal13]

I've had one a little over two years now. I live and work on the Canadian prairies. As Rawze says I'm the perfect candidate for one of these.
I have a 2013 Western Star with a DD15. I don't like to idle all night. I have both Webasto engine pre-heater and bunk heater, they use up some of my battery power, plus the fridge kicking on and off all night, so the Maxwell takes the worry out of starting in the morning. I have successfully used the Maxwell down to -29C, below that I just leave the truck running. When it gets that cold you don't want to take a chance.

As far as starting the truck after fuel filter changes, it's easy.
I just move the starter wire from the start post on the Maxwell and attach it to the positive post. Then crank away as usual, after you get things sorted out, just return the starter wire to the start post on the Maxwell. Only takes 30 seconds and you don't have to wait for the Maxwell to recharge.
