As well as additional reserve, dual batteries give you more cranking power - especially important with a diesel.

Yes, duals CAN help with a plow, but a good hefty single battery and high-output alternator can also work well.

One problem you may run into with installing a second battery is where to put it - I don't know how much room you have under your F250's hood.

Battery

Untill we got new trucks, we just kept a freashly charged battery inside the truck setting on the floor. When the existing battery began to show signs of drainage, we just swapped out batteries. 2 batteries usually got us through most snowfall events. this is cheaper than trying to wire up a duel system.

Two batterie is not that expensive. On older 250's there was room under the hood. I have also seen them put into toolboxes or cases in the bed.

Even my little Toyota has duals. I bought the kit for a diesel Toyota to add the second tray. My other trucks are diesels now so I hav no problems.

I also run Optima Yellow Tops

Dont ALL makes of Trucks with Diesel engines have them?? I ordered my truck with dual batteries, and just the other year wired them together, as from the factory, it was a AUX. battery that was isolated. I wanted the increased capacity of joining them together. Battery trays are available for all Chevys, just look for ones with the Diesel engine, then buy some heavy gauge wire and wire them together + to + and - to -.

Geoff , i had dual batterys in my 94 f250. moved the charcoal can that was right behind the stock battery and then bent the bracket down and installed the 2nd battery right behind the 1st one. i set it right on top of the plastic wheel well liner and it did fine for two years however i allways ment to make a mounting plate for it.

There is a kit out there that replaces your factory battery tray, with a tray that will hold 2 Optima Red Top Batteries, not sure if the yellow is the same size. This kit requires no modifications to the truck from what I have been told.

I am looking for this kit and when i find it I will buy it. The truck will then have 2 optima batteries. I found that when we connected a second battery to the truck, that all the voltage problems went away. The 95 Amp alternator was fine, when you had two batteries with 850 CCA.

I have 2 Optima Red Top Batteries hooked up on my '84 dodge, gas. Also 114 amp alt. Have plenty of power.

Just a suggestion, if you change your alt. repleace the voltage regulator if you have an external one.

Sorry I was looking for a picture of it. Could not find it though. I basically did what you described in the kit. I made my own plate and mounting straps.
Optima Red and Yellows are the same size approx. I used the Yellows per Optima. They fit in perpendicular to the way the original battery went in.
Add the extra terminals and cables and you are set. This will make a huge difference on a gasser.
Another option I have heard is to modify the other side with a diesel intake and put the battery where the second diesel one goes on the driver side.
