I would like to change to a dual battery setup. What electrical equipment do
I need to make it work? -- Message posted via CarKB.com http://www.carkb.com/Uwe/Forums.aspx/4x4-cars/200607/1 |

dual battery
It is a 68 IH 4x4 p/u and I would like to have confidence that the engine
will crank. If I could switch from one battery to another, it would be nice. I have been in the situation where the battery went dead while on the trail and it is more than just aggravating. -- Message posted via CarKB.com http://www.carkb.com/Uwe/Forums.aspx/4x4-cars/200607/1 |

I would just parrallel two of them because you will get more than twice the power that way. More than running each one down seperately because battery efficency drops as load increases due to interan resistance and gassing and spliting the load between two batteries reduces load per battery and will also give you a lot more starting power too, even when they are nearly dead. ----------------- The SnoMan www.thesnoman.com |

dual battery
One should only parallel two batteries if they are of the same type and age
otherwise the poor battery will drain the good battery until they both put out the same voltage and you could end up without the ability to start your truck. Furthermore, if both batteries are low your alternator may not be able to charge them both at the same time and could overload the alternator (though with a '68 you could probably put in a big enough alternator to compensate since you don't have all the electrical draw that modern trucks have). If you just put in some kind of switch (i.e. a solinoid) then when you cross connect the batteries the poor battery can drain the good battery very rapidly which can cause all kinds of problems, even a fire. I recently added a dual battery setup to my Dodge and went with a Hellroaring BIC-95300B isolator/combiner which is designed to provide a backup starting battery. It cost about $250 for the unit, remote switch and shipping, but I think its worth it. Under normal operation, the truck runs from the main battery. Once the main battery reaches a full charge the backup starting battery gets charged. When I shut off the engine and there is no charge going to the batteries then only the main battery is connected to run the radio, lights, camper, etc. If the main battery doesn't have enough amperage to crank the motor, I throw a switch in the cab and the backup battery is combined through a regulating circuit so as not to overload the battery cables and I have enough current to crank the engine. You can also combine the batteries if you are using high current devices like a winch. I have used it after camping for over a week, using the lights, fan, stereo and water pump in the camper. The battery monitor will indicate a poor or weak battery (I don't know what voltage the indicator is measuring for it's various levels), yet I throw the switch and viola, the engire cranks without a problem. Before then, if the monitor got down to poor, I would barely have enough current to start the engine on a warm day.

I don't think it's fair to call that vehicle a p/u. It's more like a
tractor with a p/u bed on the back. I bet it will out-pull just about any pickup except a diesel with a high gear ratio. I wish IH still made consumer products. The '81 Scout II concept vehicle had _lots_ of promise.

This is GREATLY overstated. I have been doing it for 17 years and I have never had a "matched" set of battieries and NEVER had any problems. I have two vehicles with dual batteries too and I get great battery life.(and let me tell you, snow plow duty is tuff on batteries) I typcally replace the main battery every 3 years and move it over to the aux postion and get a total of 6 years or more out of a battery. They last a lot longer because the total load on them per battery is greatly reduced. You just do not want to parrallel a deep cycle with a regular car battery or a maintainance free with one that is not thats all because they does have different working voltages for ful charge (maintainance free is higher) and you will have problems. ----------------- The SnoMan www.thesnoman.com |

You could say the same about my old J20 Jeep P/U too because it is tuff as nails and tuffer than any new truck of any brand. Few creature comforts though. It hauled 20K plus grain trialers for first 7 years of life and then plowed snow until a few years ago and it still runs and still stock drive train too. ----------------- The SnoMan www.thesnoman.com |
