2 batteries will be better especially the further NORTH you live.

You will get much longer life out of your batteries if you go ahead and put two in it even if you are in a mild climate like I am.

I agree with the other good gents, if it ever gets very cold where you live Id opt for two twelve volt batteries in paralell. In paralell the CCA and Amp Hrs of available stored energy is additive........

I was under the impression that it depended on the cranking amps. a 1000 cca in a 12 volt has more power then 2 6 volts that have 600 cca. I went to a single 12 volt in my 70 and it cranks faster and longer. We have cold weather here to, it starts below 0

This is about a 4010D, not a 26hp big brother. I bought one once and I kid you not the battery was a single trolling motor deep cycle, not combo start/cycle but deep cycle and the farmer I bought it from had been using it for several years. I absolutely couldn't believe it after you read what you are fed by the news media about low cranking currents from regular deep cycles.

I ran the battery for another year or so before I bought a single 12v series 31 HD OTR truck battery.

But I live in N. TX. and winters aren't all that severe.

And that's the truth!!!!!!!

In series the CCA nor the Amp hours is additive, only the voltage adds. In paralell voltage is the same while CCA and Amp Hrs adds.

Co John s,
Look in the 2440 battery thread for my post there on the large single 12v battery I run and guarantee that the 1600 cca battery I have gives me higher cranking voltage (measured at the starter) and faster cranking and more than enough reserve power than I have had with 2 12volt batteries and I never had it slow down in the least cranking my 4020D. The battery was 120$ at teh local farm chain store, I have had it for 2 years now, -10 degrees F did not phase the battery at all when I started it up (and I could not use my block heater so it was totally cold). Run 00 short cables both directly to the starter and you will not be sorry. It is physically larger than 2 of the "skinnies" put together, taller longer and wider. I had 2 high performance skinnies in paralell before this and I can tell a huge differance. Make sure you have a good starter like the 4.0 or 5.0 kw Denso starter. Better batteries on the 2.3kw delco Deere gives you in kits and put on a lot of 12 v engines is like putting perfume on a pig. I put a picture there as well showing my set up.

email if you want more information on what I have set up. just keep in mind two batteries means more cables and connections to corrode, more cost in batteries to buy and replace them, more places for problems. I always try to keep is simple and straight forward.

I understand what you said about 2 12 volts in parallel being better, but if your replacing 2 6 volts with a 12 the 2 6 volts would be hooked in series. I know his 4020 is a lot more engine then my 70 is but on my 70 I found the single 12 volt is better then 2 6 volts in series

Yeah the thing is you have to make an apples to apples comparison. Given all else equal, the more lead and the more plates (about same as more WEIGHT) the more STORED ENERGY. As an example, two light wimpy twelves in paralell may or may not store more energy then two super heavy sixes in series IT ALL DEPENDS ON HOW MUCH LEAD AND ACID N PLATES.

Fun discussion for us sparkies at least lol

Take care

Compare the cubic inches being squeezed during the compression stroke on the 70 vs the 4020. Then factor in the compression ratio.
Not a whole lot of difference.

John T, weight does sound like a pretty good idea. For fun I will weigh my battery when I take it out here soon. I bent the case frame some and plan on fixing it. I will measure dad's 12v skinnies too. Pretty curious about how they compare.
