Battery size

Do the group 31 ned to be trimmed a little in order to fit under the clamp??



Does anyone have the cca to copare between a 31 and a 65??



I'll likely go with the Diehard Platinum 31's when it is time.



Thanks.

I installed the group 31's in my '01 thus replacing group 27's and not 65's; so I won't be able to tell you how much work to make them fit. I know it was very easy on the '01. As far as I know the group 65 is 930 CCA, and the groupd 31 is 1200 CCA. Good luck.

Thanks for the info... I'll compare case size beteween the 31 and 65 .

Sadly, I am replacing battery today in my 06 and disappointed that their is not room to go bigger than 65's in my truck. Hoping to get more than three years out of this next set.

batteries

so has anyone gone to a 1 battery setup? with the hefty pc2100? I need new batteries b4 winter but im on a bit of a budget and 200 is easier to swallow over 400..... it seems like the 2100 is capable over a normal lead battery... also is sears the best place to purchase?

Batteries

I actually installed two group 31 Die Hard Platinum batteries (Made by Odyssey), but with a better warranty and no outrageous shipping costs. Have only had them for over a year now, but it's hard to beat the 1200 CCA's per battery for sure. No more hard starting, even at -30 last winter.

Im looking at batteries also looked at Odyssey and wow are you trying to turn over the space shuttle. They look like the one for me

Actually I run a Webasto and want to make sure I will not be stranded no matter how cold it gets. Haven't had any issues so far and I hope the trend keeps up! Oo.

Hey Guys, I have had odysseys and beware if you get them because you have to have a special charger if you need to charge them up. They cant take over 15 volts when charging and most car chargers go up to 17 or 18 volts. .

I also did a 1700 amp single battery odyssey and it didn't stay charged in the winter,. . then I ruined it with a regular charger. . didn't know about the sp. charger then... . I then bought 2 new Odysseys, bought the special charger, it did a little better but they still don't do well in the cold. . Had to charge them up 2 or 3 times during the winter. . mostly because of the grid heaters. . I had the grid heater savers as well that turn off sooner... If you have the batteriy blanket, then they might do better... If you live in a warmer climate, then 2 of the 1700 amp batteries will do well. . just get the special charger if you need to charge it up.

If you use a regular charger on them, it has to be on a trickle so the volts are low. . if they go too high, it ruins the battery... Call Mr. Bob who sell them and ask him... . After that, I bought the Wal-mart , Yellow batteries called Ever-Start... Did great and never had a problem with them. . very in-expensive too.

I've heard of the issues with this, but do have an appropriate charger for the batteries, but have not yet had to use it. I have been extremely pleased thus far with the performance of the batteries as I have now had them for over a year now, and had absolutely no issues with them last winter even with the -30 temps we saw. Never have had to charge them, they have been working flawlessly for me. One of the main reasons I got them is because I was sick and tired of the corrosion issues with other batteries, and this has not been a problem with these of course. Oo.

Wow, Eric, that's the first black mark on Odyssey I've heard! I'm sorry to hear you had such trouble.

I managed to squeeze group 31 into my battery trays with just a little persuasion. :-laf

It wasn't as hard as I feared it would be. A little trimming on the trays and the batteries, and they fit like they were stock. Problem I had it they were initially shorting out on my oil soaked hood liner. Took care of that problem easily enough as well... :-laf

OK... sounds good, but what year is your truck??

From his profile I believe he has a 98, with group 27 batteries originally.

Whaddya guys think about this, other then OMG that is EXPENSIVE!!!



DieHard Marine Battery, Platinum PM-1 - Group Size 31M (with exchange)



Is running a deep cycle/ marine application battery OK with our alternators, or will these batteries have a shorter service life if they are NOT cycled deeply??



All opinions welcome... . :-{}:-laf

That's what I have been running for almost a year and a half now. No issues yet. I couldn't get a group 27 of that type battery, so I opted for the group 31, marine version. No regrets so far, and I will be happy to post if I do encounter any problems (hope I don't have to though... )

I guess I missed that ypu were running the marine version, but now that I see the 31 is ONLY available in the marine. Sure looks like a superb battery, I am all about redundancy, BUT I would think a person could get away with only one of these monsters, and leave room for other goodies (compressor, filters, whatever... on the other side. )



Just curious, does anyone know which battery would be easier to leave out if one were to go that way... . I am guessing to leave the drivers side by the fuse box and drop the passengers side by the air filter;



Would there be any problems with running only one of these??

That's my opinion. The drivers side is the one to keep.

You can move to single battery, but my suggestion is to get one that has at least the same CCA as the sum of the factory batteries. That would be 1300 amp, I believe.

But it will vary by user. Users in perpetually warm areas may only need one 750 CCA battery. Users running thinner oil won't need as big a battery.

I have always thought that oil viscosity is the main factor in determining your battery size. If you're cranking 15w-40, particularly in cold weather, you need a TON of energy. If you're running 5w-40 synthetic, you don't need as much energy.

Having said that, my opinion has always been "run the biggest battery that will fit". But then, I run 15w-40 and I live in a cold climate.

If you are going to drop one battery, it should be the one on the passenger side indeed. There are plenty who have done it with no ill effects. My twins setup allowed me to keep both batteries and so I did as I do not wish to get stranded anywhere due to lack of power; and since I run my Webasto a lot in the winter I preferred not to take any chances. If you live in an area that does not see bitter cold weather, I don't think you would have much to worry about.

AutoZone Group 65

I have two group 65s from AutoZone(850cca), and the cost was just over 200. 00. If you don't have a winch and a ton of lights this is cost effective.

so has anyone gone to a 1 battery setup? with the hefty pc2100? I need new batteries b4 winter but im on a bit of a budget and 200 is easier to swallow over 400..... it seems like the 2100 is capable over a normal lead battery... also is sears the best place to purchase?

 

[The patriot]

Correct. A 98.

It was warm out and I just coaxed them in. The plastic spread a little and all was OK.
