Before I run out and buy a charger I thought I would ask. I have a car that has been sitting for about 10 months and the battery is dead as dead gets (although only a few years old). It is next to my RV and I tried to jump it using the RV chassis battery. It took so long that I gave up as I didn't want to do that to the RV any longer.
The car is next to my RV steps and house batteries (under steps in sunseeker). Will I get any more direct jumping power from the house batteries WITHOUT harming them or the RV electrical system? I don't car about the car I am jumping as I will either scrap it or donate it. If I donate it they will pick it up, but I was going to try and get it running for them.
If hooked up properly it should work without harming anything, however, the chassis battery is the better choice for starting as they usually have a higher cold cranking amps rating.

After the house batteries are charged back up from your efforts, Disconnect gnd from car battery and jump Pos house bat to Pos car bat then Neg House bat to car frame or disconnected car gnd. Your house batteries were being drawn down by dead car bat.

Kind of thought the chassis was best but was reaching for a quick solution. Thanks. I might just have the donated company tow it away and be done. They will put it to good use.
Another thought - ethanol fuel tends to go bad quickly and can foul the fuel system in the car. If it cranks and won't start, that could be the problem.
Trying to crank off anything to a REALLY DEAD REALLY DEAD battery can be futile. I have had two really big over priced Robert Bosche five year replacement guaranteed batteries DIE in my Ford Explorer so dead that the big Double O gauge cables from the giant AUTO CLUB tow truck could not jump start it. Told it was a direct short inside the battery and no amount of cranking gave it back enough juice to even run the ignition system. MORAL OF STORY don't give up until you take the battery out and put s good one in its place. Besides that the house battery is deep cycle and may not have enough CCAs to do it.
That's strange when your jump starting granted a bad battery will take some of the cranking amps but you are really by passing the battery and going right to the starter/ignition. You can always disconnect the battery and jump to the terminals only.
Bought the Pro-Logix (Solar) from Clore Automotive, to keep the TT battery maintained through the winter. The charger also saved a deeply discharged TT battery, that paid for the charger. Won't start a vehicle, but sure keeps all types of 6/12V batteries maintained.

This is the best idea so far. Probably the safest.

There is dead and then there is DEAD. My two experiences with Bosch High End battery in my everyday car has been DEAD SHORT INTERNALLY DEAD! Just saying that before he has the car towed to the junk yard maybe it would be worth a battery change out. Full replacement warranty and NUMBER 3 is holding up so so at two year of age, it just has outlasted the first two and the warranty has expired so I expect another DEAD DEAD any day now.
