Got a question or two for you battery experts.
My 02 Dakota is about ready for its first
battery replacement. With that said, I helped my
Son-In-Law get his van started the other day. His
battery went dead. I don't like jump starting
from one system to another so I used a fully
charged battery I remove from my old AMC while
the car is in winter storage. That battery would
not turn the vans starter over very fast. He also
has (will replace today) starter problems. What I
did next was I used my half charged DEEP CYCLE
battery out of my stored RV camper. It rolled that
vans starter over like it was a new one!
My question is, can a DEEP CYCLE battery be used
in a car or truck insted of a *normal* battery?
Will the car or trucks charging system *boil* the
crap out of the deep cycle battery?
Thanks for any input guys...

Theoretically if it gave out enough amps, yeah you could use one. Truck starter probably takes a very large current draw in short bursts. Large deep cycles should be able to handle this.
But of course they are designed to have low to medium current draws over long periods of time. They are heavier, more expensive, and may or may not provide any benefit to you. My boat for has a dual purpose deep cycle that I use. It's just a small one that provides enough CCA for starts, but allows me to run the lights and depth finder over long periods without draining. I'm not sure a truck would ever need this ability though unless you are running aux devices while it's turned off. Your alternator should always provide charging while the vehicle is running.

Deep cycle batteries are designed to be discharged more; I'm not so sure they are only designed for low or medium current drains as claimed above though. I use several - one on a flatbed trailer that sees some pretty strong draw from a winch; one in an I/O boat that sees starting and charging from what is basically an automotive engine. Another in my camper that gets charged through the trailer wiring by my truck's alternator (the flatbed gets charged like that as well). I see good longevity from all of them - nothing to indicate the method of charging or drain causes any problems.
Lead, follow, or get out of the way

Do a google search on deep cycle batteries. Unless you have a lot of accessories that will draw a lot of power over a long period (winch, fridge, utility lights), a standard battery will work best in the long run. I awlays buy the biggest one that will fit.

As some of you may recall, I had a golf car repair business for 21 years. Somewhere in the 3 to 6 year life of golf car batteries, One to 3 will go bad out of 6 or 8. The bad ones got traded in and the rest got charged. Of the ones thatI charged, Most or all would take a 100% charge. I used some and sold the rest to guys with campers and old 6 volt restored cars. Couple of guys had wind or water generaters that used a bunch of my batteries to run there lights, refrigerator, deep freeze and power tools when needed.Nobody ever complained. Now myself, I used 2 6 volt batteries to make 12 volt IF THEY WOULD FIT. If not I used a new 12 volt deep cycle. I will not recommend A combination battery, Start-deep cycle battery. They don't start well and they don't run a winch for beans. Without question, I will install a deep cycle in my Dakota when the time comes. One think to watch. Just because the starter will turn the engine for WHAT SEEMS FOREVER, Do not do it. You will burn the starter out
