Batteries: 2013 Internation 19, Interstate SRM-24 both dead

[DoublTrouble]

I am hoping to make the switch to a pair of GPL 27 T. With my 2015 27 FB, I have the access door in the way. To go 6 volt I'd need to to more mods than I care to do. Also, for my type of camping, I would be ok with 100 amp hours per day as long as I bring my eu 2000i. HOWEVER, as I look at the picture of the GPL27, I see just 2 battery posts per battery. My setup looks like this...
Any help is appreciated.

When properly connected, you only need one positive and one negative post per battery.

There are several photos of a pair of AGM group 27 batteries wired in parallel that you should easily find in a search of battery threads.

All positive loads connect to the positive post of battery one and all of the negative leads connect to the negative post of battery two.

The parallel cables (which should definitely be larger than your 6AWG pieces of pasta) should run positive to positive and negative to negative.

You know, I've kind of lost count of the number of times Lew Farber has unselfishly stepped up to the plate to answer our questions. We are very lucky to have him around !

I thought I'd take a minute say "Thanks" and also.....

Remind folks that the batteries and converter mentioned in this thread and others are also available from Lew !!

I know we all love good deal and I'll bet Lew will deliver on that good deal AND a Good Deal More !

Merry Christmas to all and All the best through the New Year !

Put in the charger this weekend and will advise results at that time.

I had to do the same and have the same fears about replacement but will cross that bridge when I get there. Hind sight says I should have gone with the taller 6v cart batteries, raised the lid and picked up the extra amps. Lazy me....

I did however place a rubber mat to put the batteries on and drilled it to match the existing holes in the bottom of the box. Initially i was concerned about no tie down after cutting the rod, but the fit is so tight I don't think it will be a problem, though I did place a couple wedges between them.

Yes, thanks Lew. I will look for it.

as I ponder the wisdom shared, I see that, even if I made no change, the stock batteries are not connected properly from the factory. Lew, unless I am hallucinating, the negative car type clamp should be on battery two....
Then it is also true that the "less than stellar" performance of the stock batteries could be the result of this odd installation.

You're starting too 'get it'.

[DoublTrouble]

DT,

Nice work! I would definitely consider upgrading the parallel cables from the supplied 6AWG to a minimum of 2AWG. Your batteries WILL thank you!
