Thank you for reading it. My car has an electrical short that will drain the battery if the brake is pressed when the car is off. Pressing the brake turns all electrical accessaries on with the motor still off. I need advice on what is the good battery jumper box. I have a box from AAP and a Black&Decker from Walmart. Both are junk even though they are fairly new, with the Walmart one only 2 months old and never used. I was left stranded in West Virginia yesterday and they didn't work even though I charged them for 30+ hrs before the trip. Some nice fellow gave me a jump using his Snap On jumper. I can't find Snap On jumper around here but just bought a very large one from Chicago Electrics Power Tools at Harbor Freight Tolls store. This is a large model with 1200 Amps maximum discharge and 600 Amps normal discharge. Is this a good tool or should I get something else. This is a highest model Harbor Freight Tools had. Any other tried and trusted jumper by the BITOG community. I am going on a trip to Florida and really need to get one. Battery, Alternator, and chargining system were checked by both AAP and Sears. I even put in a work order at Sears in WV to have battery replacement and system check. They said I didn't need a battery after installing it. Since they refuse a $115 sale and only charged me for checking, I know they really did what is best. The problem is a short and the car needs jumping if the battery is drained again. I need a [censored] fine jumper box and cost isn't a concern but I want to be able to purchased it at a store and it needs not be way too big like those that need to be on wheels.
