My '95 had the original batt's until I sold it a couple of years ago. They were original Ford "silver" series batteries. I have a couple of Chev mechanic friends who swear by and buy the Motorcraft batteries for their GM's. When it comes time for batteries in my diesel it will be the Motorcraft ones for me...maybe "Gold: series if available. Always replace in pairs. Do you plug the block heater in at all, in the winter?

 

I probly wouldnt normaly but i had to or the batteries this past winter wouldnt have the cranking power after the glowplugs

one batt looks likr original and the others a way smaller kirklands


thanks for the heads up on the batteries, it seems im in over my head with dead batteries lol truck needs 2 plus i have 2 cars ive fixed that are up forsale both need batteries plus both demo cars need batteries.... jeesh

main things the truck, i bought a good batterie for the exploder when i was up in Fort Mac from ford it had a hefty price tag but lots of cranking amps dumb me didnt switch it out before i sold the exploder

 

I replaced mine with an Odessey Battery I like it allot, read all the info here http://www.odysseybattery.com/batteries.html

 

I put a pair of Odessey's in my 06 diesel truck in the spring. One of my batteries was an original and the other appeared to be a used Delco. I had some slow start ups in the cold mornings, so I figured they were due for replacement.

They weren't inexpensive, but I have used Odessey's in my 2 Seadoos and my Subaru STI with great success.

I picked all of them up in Hamilton at Great North Battery, located on 475 Parkdale. Best pricing I could find for an Odessey.

They fit my truck like stock (no spacers, etc.), have very good cranking amps, a good warranty and they don't leak acid!

 

When I put batteries in my truck I put in AC Delco. Not the best but are fine so far. The price was decent.

 

If your lucky, maybe you can use the diesel's batteries for the demo cars. Might last a while longer in a gasser.
