Engine jump start

More than any portable I know of. With a cold engine I'd think you'd be SOL!

 

i agree most jump boxes are worthless on a semi, a good set of real heavy duty jumper cables would probably be better.

 

Something like this? http://www.toolsource.com/3400-/-17...eid=googleps&gclid=CMnQ3u76kcECFTDl7Aod3FoAgw

 

Most trucks have 3 to 4 batteries 800 to 1000 cold cranking amps ... Best winter maintenance is go get batteries load tested replace them if they test bad ... Keep connections clean and a set of jumper cables .. If you pull refeer you have a 53 ft battery charger all you need to do if hooked up is connect positives together truck and trailer are grounded already I have a smaller jump wire I sometimes use to keep batteries up when running bunk heater on a layover

 

You can jump start your big truck with any vehicle that has a 12 volt system. Hope you never need to.

 

U can start truck from any car, just run car connected to truck batteries about 15 min and truck will start

Other good idea - just install APU

 

I gues I would spend the same amount on 3-4 new batteries, than this unit. but it is nice. If I had one, more than likely I would be using it to get everyone else started, as I buy new batt,/alt starter on a timeline, instead of when they go out, which is always away from home.
