One battery?

[hondarider552]

Who runs only one battery? my passenger one is dead, and id like to only run one. Here in az the winter temps are like 50-60*, and the truck is parked in the heated/ac'ed garage. never have had my glow plugs come on in 26k.
pros and cons?

 

[DmaxHawk]

I think GM put 2 batteries in there for a reason

Not sure what the pros and cons are but personally I wouldnt run 1:baby:

I only run one here in Ca. because of the twins, but it makes the hour meter rest FWIW.

X2 Actually Wendy started like crap. But, I think it's because I running the original batteries.

Casper only runs one and it's Costco brand and never has had a problem.

I only have 1 in and have had no problems, only been down to about 20 here tho. And I have no grid heater either

 

[Dzlnut]

I ran one for a little while but i don't think i would try it when it was very cold out.

 

[1badmax]

I run only one battery, no problems.
I dont drive my trk in the winter either...

 

[12secondhandshaker]

I run one battery in the summertime as long as its above 50ish its no problem.

Make sure its a good one though! I flew out for a 4 day trip in the fall and it drained the battery and it never came back 100% I ended up replacing it(GM original) just before winter.

thanks kat for the link, looks like i might be going to costco or walmart today then
I dont even trust 2 ac delcos.

 

[duratothemax]

you're fine. here is mine at starting at -7* on one battery sitting outside all night without being plugged in.

[hondarider552]

cool thanks ben. did you just use the ac delco or the costco ones?

 

[duratothemax]

whatever generic one Advance Auto sells...

something titanium?

Lithium?

Ben found a Autolite platinum. this what you have?

Found this:

[duratothemax]

no. its titanium. (im not saying that to be funny ha ha, it actually says titanium on the side ill take a pic )

If you go into Advance and say "I want an OEM replacement battery for a dmax", its what they give you. I think it was 90 dollars.

Just throwing this out there -

Wouldn't it be harder on the battery, starter, and glowplugs to run an LB7 on only one battery versus the LLY and LBZ?

IMO, at least in theory it would, due to the higher compression and glowplugs taking more voltage.

As in it wont keep timing the hours on the truck? sweet

couple things...

the LB7 and LLY have the same compression.

Its hard on the battery yes.

not hard on the starter IMO

the LB7 glowplugs use higher voltage, but lower current. LLY+ glowplugs are only 4.7 volts, but draw roughly 2 1/2 times as much current...... 6 1/2 dozen or the other as far as I know.

I was under the impression the LB7 was the highest compression....but if they use the same pistons they should be the same.

Thanks for clearing it up.
