I'm looking at picking up an Odyssey 2150 battery for my 91 F-Superduty. Is there any reason I couldn't get by with a single battery? I can't really justify spending what two of these Odyssey's would cost for this truck.

It's pretty much parked over winter so there won't be a need for a lot of cold weather starting.

I'm going to replace the battery cables and I've got a new starter for it too.

 

I'm sure it's fine, but why risk it?

 

Well I want to run an Odyssey battery but don't want to spend $750.00+ for a pair of them!!

 

I ran my 89 F250 diesel on one Optima battery with no problems, but I live in Texas where it's pretty warm.

 

Im running mine on a single battery atm (untill I can get my battery box built on the flat bed), cold starts are a little interesting but otherwise it gets along fine

 

What kind/size of battery are you running?

 

Factory sized battery, think its a duralast but not sure, just whatever came with the truck last summer when I bought it (had 2 at the time, removed the pass side one to run my intake there) in any case its just a pain jane factory sized battery that works but startings a little harder (also partly due to bad cables and so-so glow plug harness)

 

The battery I'm getting is a group 31 with 1150 CCA.

I'm going larger then stock new battery cables, new starter, all new glow plugs & controller, rebuilt IP, new injectors, return line kit & a Carrier/Facet electric fuel pump.

So I'm hoping it's not going to be hard to start. I'm going to be using this truck to haul scrap metal, spring thru fall. It will get parked over the winters. So I'm not too worried about cold weather starting. I just wasn't sure if that was the only reason for dual batteries.

 

since you have good glow plugs and an electric fuel pump, it should be fine on one of those batteries. honestly it shouldn't take more than 2 seconds of cranking on a bad day, and one battery will have no trouble with that.

but in stock form with only a mechanical lift pump, an air intrusion event will leave you needing about 60 seconds of cranking time, and thats almost all that 2 stock batteries can produce. a single battery in this case would be unwise

 

1150 CCA is only two-thirds what you're supposed to have (two 850 CCA batteries) ... your engine will crank slower than it should, and that means you'll have difficulty building the compression to ignite the fuel. It might work, it might not. Why not just spend $200 on two properly sized batteries with a three-year warranty?

 

If you go to a gear-reduction starter it will cut your amp requirement for the starter by 1/3.

 

I seriously doubt the engine will turn over slow with this battery! This battery is rated at 2150 HCA. But if I'm wrong I guess I'll end up having to fork out another $380.00 for a second battery.

Last summer I just hauled two properly sized fleet farm batteries, 2 years old, to the scrap dealer because they were crapped out. If I went with standard batteries again they would be at least 1000CCA each. And that's more then $200 for the pair.

I want a deep cycle battery ( sits all winter not being used ) that has cranking power. This battery does. Plus this battery has a 6-10 year service life. So in the long run this will save me money over buying standard batteries.


Once I get the truck to the point of using it more then I'll throw a pair of these Odyssey's in it.


Has anyone here tried running a single Odyssey 2150 battery?

 

That's what my new starter is.
