Is anybody running a single battery if so any one in particular that works well ?

Your alternator charges at 14.4 volts roughly so the electronics of the truck are used to that voltage. I'm pretty sure you'd have to mod your alt to charge @ 16.4 volts though, in order to run a 14v battery. Just extra power allowing you to run one battery without any negative impact. But a single 12 should do just fine 99.9% of the time.

I have 2 AGM batteries in mine and it snaps the engine over well, using one battery you might want to consider a higher amp alternator at idle. I'm looking at one right now that puts out just a tad under 150 amps at 710 rpm idle where I want it and not using an underdrive pulley (smaller diameter). It's not a high priced Denso hairpin like Mechman etc. sells and has the OAD not the OAP pulley.

I run a single Battery for weight reduction. Like others have said it is slower cranking but I have no trouble even in the winter but I do use my block heater over night.

Share please Just last week I linked a Dmax buddy to your info on alternators; he needs one soon.

tusconalternator.com, I bought the parts for the hi-amp alternator feed wire not the kit so I could install the fuse in another location.

The graph shows alternator RPM not engine RPM based on a 2-3/8" alternator pulley and a 7-1/2" harmonic balancer at about 2200 alternator rpm with a 710 engine rpm This does not take into account for heat loss which is a minimum 10% and goes up from there and where I live heat is a major factor.

I've been running a single Die Hard Platinum AGM battery (basically the same as an Odyssey). Haven't had any issues at all. Starts fine every time.

I run the same one on the outside of my frame just before the rear tire. Works great!

 

[prostreeter600]

Anybody run a single Optima ? Do they hold up ?

 

[1SloLMM]

I use a single diehard platinum on my lbz but it the group 31 marine battery and weighs 75 pounds but has 1150 CCA. Put it in the way back to put more over the rear wheels.

I also have two of the stock size in my lmm and they never have given me a problem starting even after sitting for a couple months in the winter. I believe they are 800cca. Get the for 175 from sears on sale

I've run a single red top for the last 5yrs...no issues. It's a little slower to turn over but that isn't a big deal. If your worried just disconnect one for a couple weeks to test.

 

[plowboy_lbz]

I ran a single yellow then switched to a red top (more cca). If the truck was going to sit very long I would unhook it. A lot of short trips are hard on single battery set ups. Always carried jumpers.

 

[prostreeter600]

Oh, not wanting to have to carry jumpers all the time . Lol

 

[Dozerboy]

Well you could just carry a booster around with you then.... which is a battery...maybe just keep 2. Lol

I hear ya. Lol. We do strange things to try to go faster . I may give the Red Top a go . It's between the Red Top and the Oddesey .

 

[PACougar]

I'd get the Oddesey, you kill a Red Top once and they seem to be dead forever. Plus they don't like the Texas heat in my experience.

 

[prostreeter600]

I hear ya

When I researched batteries for my puller, I seen a lot of negative feed back on the Optima batteries. Apparently they were bought out a few years back and have since gone down hill. I read nothing but positive things about Odyssey batteries, off-roaders with big winches love them!

 

[Woodster]

AC Delco's lasted 4-5 years. Deka's lasted 2-3. I'm using Optima's now. No problems yet, loving those CCA at start up though. :thumb:

I had Optima batteries back in 2008-2009. In those 2 years, I went through 5 batteries, all under warranty. I finally got tired of being stranded with a truck that wouldn't start, and gave them away to some chump, and have been running the cheapest batteries I can find. I figure if I get stranded, it might as well be from being a cheap ass. Oddly, the cheap ones have yet to let me down, but usually only last 3-4 years.

From my saga with the Optimas, I found that you can start the truck with one battery just fine (even a cheap one), it just cranks slowly.

Hopefully Optima has sorted out their issues. It has been almost 8 years since then. I'm due to replace my current set of cheap AutoZone batteries, maybe I will risk the price of Optimas and give them another go?

I ran these for a while in my LB7. no batteries at all. cranked over ridiculously fast. one set cranked over as fast as two lead acid batteries. both sets cranked over faster. also they weigh about 10 lbs total. that is some weight savings





Specs:

They are 2.7 volt 2.85 surge, 3000 farads - yes 3000 farads.

I wired 6 in series to make 16.2 volt (17.1 volt surge) 500 farad bank.

Two of these make a 1000 farad set to replace the batteries in my truck

good down to -40 degrees all the way to 149 degrees. the set has 4330 CCA/CA & and short circuit current of 18,000+ amps

the engine turns over and starts so quick and it recharges in less then 30 seconds. the audio system seems to have gained an extra kick too

right now i have them temporarily tied down in place of my old batteries
