North Central Alabama | I just bought a a 20' 20,000 lb. rated dump trailer with a electric over hydraulic Scott level load model# 800DH hoist.I am planning on hauling chicken litter with it.I called the manufacture of the hoist and give him measurements of where it was located underneth the bed and he said it should lift 11.9 tons @20' i was thinking about putting a partition 24" from the front and making it a 18' and the lift capicity goes up to 13.9 tons.The bed probally weighs 2.5 tons.The engineer at Scott said it would pull 275 AMPS when lifting the first couple of feet.It needs 2 new batteries do i go with deep cycles or regular starting batteries?

Manitoba | Go with Optima batteries http://www.optimabatteries.com/us/en/ Expensive but worth the money IMHO. They are virtually indestructible and have great cranking power. |

North Central Alabama | I like Optima too.My question is do i need to get deep cycle? |

Hagen Brothers farms,Goodrich ND | I would guess you need deep cycle, as hoist operation may deplete the batteries enough to cause a medium deep cycle. Normal starting load on a cranking battery makes terrific amp loads (600-1500) for only a few seconds, then immediatly recharges. A deep cycle battery better takes a few hundred amps draw for a minute or more, then a slower recharge.
We just converted an old gooseneck grain trailer to a parade toy hauler. It has the electric over hydraulic hoist (300-400 amps?)and an 8000 pound winch that draws about 280 amps at full load. We fitted the trailer with a large (105 AH)TSC deep cycle flooded cell battery. It seems to handle raising the bed about 30 degrees and winching a 6-7000 pound tractor on it taking about a minute on the winch. loading / unloading the tractor twice leaves the battery at about 75-80 % charge.

Northeast Indiana (Auburn) | How many lift cycles per day? I ran one 12volt group 31 on the trailer and had welding cables connecting the trailer battery to the truck battery. The most I would cycle was 8 times a day. If your truck is charging the trailer battery you won't need two batteries on the trailer. If you are going to charge the trailer batteries only at night with a charger you will need two group 31's. |

Ohio | We run ours off of the truck battery. We ran cables from the battery back to the truck bed and used one of those heavy quick connect plugs. I can't think of the name of them right now. So your getting the output of the battery plus the alternator and you don't have to screw around with recharging the battery on the trailer. |

WC IL | Probably could use a plug like on an electric forklift. |

Central / West Texas | I have a trailer similar to that. We have 2 group 31's on it and a trickle charger hard wired to them. I have a plug in the bay of the barn I keep it in and keep it pluged in all the time. I can make 5-6 dumps in a day and it seems to lift just fine. I have never made more than 6 dumps with it without plugging it back into the charger |

NE Indiana | I have one like it and run a deep cycle Interstate battery. Been in there 6 or 7 years and going strong. No experence with Optima batterys. |

Goff, Kansas (Nemaha County) USA | We have a electric/hydraulic grain trailer similar to yours, we also ran cable to truck battery, also have one setup on tractor too if we want to use it to pull it. We used the ball as ground and ac/dc welder lead connectors to quick disconnect. Cheap and easily replaceable from just about anywhere. We have it and the trailer connections in the bumper of our trucks and use a piece of small angle iron to make a bracket to hose clamp it in place then chopped off the front face of a 6 pole trailer connector to act as a dust cover. Works well and you never have to worry about the batteries being charged on the trailer. Also keeps all the neighbors from borrowing it too! ;-) |

Northeast Indiana (Auburn) | Don't count on the ball for a ground. When the trailer is about empty dumping the weight of the load left will for a second or two lift the hitch up off the ball causing all of the small ground wires on the truck handle the pump motor grounding. I burnt up several cab to frame, frame to battery wires before I figured out what caused them to melt. Thats why I added a second welder cable from the battery to the trailer for a ground. I had a grain trailer that when going up the grain would slide to the tail gate and build up as the grain was going out the small grain chute causing the front to lift. If you open the back up then dump like you will with chicken litter you should not have that problem. |

Type of batteries for dump trailer?
