deep cycle batteries

[itbrokeagain]

Any reason I can't run one in my 80? I'm thinking high drain things like winching or sitting on the trail with the engine off and radio on would be better with the deep cycle. Any thoughts?

A true deep cycle battery will work fine, but will have lower CCA. The hybrids (like a yellow top) will be between a deep cycle and a regular auto starting battery. Lots of info on the net. Try this site for basic info Deep Cycle Battery FAQ, Marine, and Deep-Cycle Batteries

Also, cut over to the Expedition forum for some good battery talk.

Sears Die Hard Platinum - biggest one you can fit in your battery tray. You could get the Marine version, but there's no reason to unless you are using low power items long term with the engine off. The Marine version might make sense as a 2nd battery if you switched over to it while parked/camping.

I run a pair of Blue tops in my rig (despite all the Optima hatred on this board) with zero issue

I also run way more electronic goodies than the average guy (dual winches, mobile theater, On Board Air Compressor, 1300 watts of auxiliary lighting, Emergency strobe lights, Multicamera Video Surveillance System that runs 24/7, etc., etc.)

What you have to remember is that ANY battery (regardless of type) will eventually drain if you forget your lights on

That being said, a Deep Cycle battery (in most cases) will recharge to full capacity, whereas a standard starting battery runs the risk of never seeing full capacity after being discharged

I think the Sears Platinum auto and marine batteries are identical internally. The difference is the marine batteries have auxiliary posts for accessories and they only have a three year warranty instead of the four year warranty for the auto batteries.

Here's an older giant thread on batteries. Count me amongst the dry cell haters. Just my experience.

AFAIK: Die Hard Platinum (DHP) = Odyssey.

If DHP Auto is identical to DHP Marine, both are apparently identical Absorbed Glass Mat batteries (Odyssey re-badged) then it's handy that the Marine batteries are on sale right now.

I have a DHP in my 80 now, but it is the same group as the stocker... I am going to transfer the current DHP to my 4Runner, and buy another for the '80. Do you know what the biggest one is that will still fit without (much) modification?

 

[Black Rhino 13]

I have a DHP too and will get my 2nd as soon as the price drops online. A week ago they were $50 off online with in-store pickup. I would grab a Marine Group 34M now at $165 but there are none nearby. The Group 75 is tempting, but I need to measure my new battery tray and think about it some. I haven't finished trimming the PS battery tray yet. Other projects have taken precedent.

There are threads on this elsewhere but as it's really simple I'll throw some numbers up here:

Marine battery:
Group 31M 13" x 6.8" 1150CCA 75LB Positive terminal on the Right

Group 65 11.8" x 7.2" 930CCA 60LB Positive terminal on the Left
Group 34 10.9" x 6.8" 880CCA 53LB Positive terminal on the Left
Group 35 9.5" x 6.5" 740CCA 50LB Positive terminal on the Right
Group 25 9.5" x 6.9" 740CCA 50LB Positive terminal on the Right
Group 75 9.5" x 7.9" 710CCA 45LB Positive terminal on the Left

In case this isn't intuitive, the factory battery has the positive terminal on the passenger side with the posts toward the front of the vehicle, IIRC. If you buy a battery with the positive terminal on the driver's side, you have to make some kind of adjustment. I flipped the battery so that the terminals faced the rear of the vehicle. Then the negative terminal is on the passenger side of the engine bay and you have to replace or relocate the negative cable. The positive cable can still reach the positive terminal by unbolting a hold-down or something. It's all simpler and more intuitive when you do it. I also ended up putting different terminal clamps on, the ones with the bolt and wing nut for quick release so I can easily add/remove accessories and/or the whole battery.

IIRC, Group 35 is the one recommended for the LC. I went with the Group 34 and did some minor modification to get the Neg/Pos cables to reach. It's worth keeping in mind that the factory lead acid battery has around 480CCA. Any of these is a significant improvement over stock, from that perspective.

I don't know what the max dimensions are. A quick trip to the vehicle with a tape measure is as good as anything. I have Slee's light harness installed and the little relays are mounted in the area with my battery. I've changed my charcoal filter out for the GM version and changed how it mounts, removed parts, changed where my neg. cable attaches to the LC, etc... I like it and I think it works very well.

People will modify their battery trays to hold a more powerful battery if they want it that bad. I'm in the middle of trimming the battery tray for the passenger side to get it to fit. That is on the back burner at the moment.

I've been running dual Die Hard Platinum Marine batteries for over 3 years now and haven't had any issues. And yes, from what I've read, they are manufactured by Odyssey.

Marine battery:
Group 31M 13" x 6.8" 1150CCA 75LB Positive terminal on the Right

Group 65 11.8" x 7.2" 930CCA 60LB Positive terminal on the Left
Group 34 10.9" x 6.8" 880CCA 53LB Positive terminal on the Left
Group 35 9.5" x 6.5" 740CCA 50LB Positive terminal on the Right
Group 25 9.5" x 6.9" 740CCA 50LB Positive terminal on the Right
Group 75 9.5" x 7.9" 710CCA 45LB Positive terminal on the Left

I measured my stock battery tray, and the max battery size looks like, 12.75" wide, 7.5" deep, and 10" tall. That's w/o modifications.

I would like to fit that Marine 31m in there, and it looks like it would go in without too much trouble. For the $, it doesn't looks like you could get a better battery right now. There's plenty in stock in my area, so it just might be time to get that dual battery setup going!

 

[Black Rhino 13]

^^^ I haven't measured in a while. Are you referring to 12.75 as the plastic/fiberglass tray dimensions or the width allowable by the metal battery hold down bar?

TWO 31M's would be something if that's what you're talking about!

Might have to upgrade to the OME 3" or 4" Comp's with 150+LB of batteries up front.

 

[bryson]

I came across these today... another rebadged Oddysey? For $149 it is very tempting! There are most sizes available.

I run dual Die Hard Platinum Marine batteries 31M in my cruiser. They are awesome and fit better in the tray than the biggest yellow top. The DHPM 31M also have a higher CCA and reserve capacity over the biggest Optima Yellow top.

I'm referring to the tray dimensions, I dunno about the holder.

So you fit them in nice then, no crazy fighting to get them in there? That's what I wanted to here, a couple 31m's should keep me powered up for a while.

 

[itbrokeagain]

Right now I am running a interstate. I have an optima in my xj and I had it in the 80 but for some reason it didn't like the 80. It would discharge quickly. I have access to marine batteries at work so this was my next thought. I just didn't know if there were any major drawbacks to sticking them in the 80. Dual batteries are a thought also. We will see.

They fit snug as a bug lots of off road trips without a strap on them. You do have to trim the fins a little on the side of the battery but it is super easy and takes only a minute. The rear part of the OEM tray has a slight triangle bulge. You run into a similar problem with the Yellow Top but the DHPM can be adapted much better for a perfect fit. The DHPM also has a nice carry handle to help with the install and removal. I have lots of electrics running to my batteries, 5000w FyrLyts, 50qt ARB fridge, Full Kicker stereo system with 12" Sub, PUMA OBA, TJM 12,000 winch, etc.

Its the perfect setup for me. I like to play music while camping, or hanging out at the river or lake. My system can play all night without any worry of the cruiser not starting in the morning. My fridge also runs comfortably at 32F all at the same time for days on end. I also leave my phone charging and let people fill up their air matresses without starting the cruiser.

I was a die hard Optima believer when my two red tops powered my car with a failed alternator from El Golfo Mexico to Yuma at night with high beams on. Since trying the DHPM I am very confident they are a superior battery and the specs show this. I also ran all of the same stuff on one DHPM 31M before I purchased my dual battery setup and it ran great. Before that I had a regular DHP OEM spec and it was fine until the first discharge. It made my fridge act weird and was a disappointment. I say go big (31M) or you might not make it home.

Right on, I think I may have to go get a set of these then. I may not have as much stuff running as you, but similar, OBA, 12k lb winch, fridge, water pump, lights, big inverter, and dvd system for the kids going in next chance I get. When we start camping this year, definitely gonna need the extra power.
