2012 Interstate Lifeline Batteries Orientation

Hello. First post on this forum but I've been lurking in the background since the purchase of our Interstate Lounge back in the fall. I've learned so much from this forum and can usually find the answers I need with a simple search. One question I can't find an answer to is the orientation of the Lifeline batteries. Unfortunately, our Interstate came with two small Optima Blue Top 50 amp hour marine batteries that just don't get the job done. I measured the battery box and don't see anyway that the Lifeline 24t batteries can fit in the box unless they are lying sideways. Is that the way they came originally? Or did some other brand of batteries come in it when new?
(We have an Interstate Lounge, but that choice is not in the pulldown in the profile setup)

Lifeline AGM batteries can be mounted in any orientation but upside down. Here is link to their knowledge center where you can download a tech manual which has more details.

Welcome! I'm pretty new to the group too. Our 2011 came with 2 conventional batteries stacked vertically in a box under the rear lounge. Not sure if the 2012 is similar. It's my understanding that AGM batteries can be positioned on their sided since they are completely sealed. No doubt there will be much more knowledgeable folks chime in soon with a more detailed answer.

Some have used Lifeline 6V wired in series because they have a higher amp-hour rating. However they are a smidgen taller and require some mods to the installation to accommodate. IIRC, the mod consists of a thinner partition and extra insulation to prevent the cover from shorting.

I wanted to go that route but the batteries wouldn't fit the box. Went with Trojan 12V AGMs instead because my battery guy didn't carry Lifelines. When those wear out I'd like to get the "Lewster special" with lithiums and solar upgrade!

You rang???????????

Actually, I usually remove the stacked battery box when installing Lifeline golf cart batteries and fill in the hole, level the floor and use a pair of GPL-4CT (220 A/H) or GPL-6CT (300 A/H) in the same space….usually positioned upright.

I'll see if I can find a couple of shots.

Found 'em!

And before you ask…..YES! The rat's nest of Romex cabling and bare copper grounds was straightened and properly bundled and loomed BEFORE placing the Lifelines.

Thanks for all the replies. Lewster--That's a nice and neat modified installation for those batteries. I'll most likely go with the the 6v batteries as I need all the capacity I can get (cpap machine). I wasn't sure that the 24Ts would even fit in the battery box I have since the length is slightly over 11" and the battery is 11.1", which is moot if I go with a pair of the 4t. Going with 6t batteries is even more appealing if I don't need to pay to have a modified box built. Any concerns about the minimal venting of gases from those batteries being outside of a battery box?

Sidebar - the CPAP power supply question is important to a fair number of people. Last week, my husband and I were stopped in Palo Duro by a northeastern couple who opened the conversation with, "Is that a 2007?" I was stunned that they even knew what the vehicle was, let alone its model year, but it turns out that they, too, were the proud owners of a 2007 garnet-striped Interstate. But they didn't bring it on their Palo Duro trip because they hadn't yet figured out how to retrofit it to run the CPAP machine that one of them required - so they use their Interstate for local trips only, and brought a larger RV down south instead. They were very interested in our solar array for that reason.

I got 2 GPL-4CT LifeLines to fit

I'm an early 2012 EXT Owner. I was able to just fit 2 GPL-4CT LifeLines in the battery box. Wanted to install the 6CTs, however there was no way they were going to fit.

The 4CTs fit with just barely enough room to add an insulated layer between the battery posts and the metal box. I slid in a thin 'plastic' cutting board to use as the insulating layer and hold the batteries in place.

Seems like everyone's configuration is different.

I wish you success with your effort...

Reading carefully Lewster 's email, He used one 4T and one 6T in his conversion; is that correct Lew? Does that give a total of 520 AH? AEW

That doesn't sound right. You don't mix battery sizes in one bank, whether that bank is series or parallel.

I stand corrected, thank you Protagonist, seems I missed the very important word "PAIR" of batteries. At my age I'm still learning very important things. AEW

Nope! Please re-read what I said. I use a PAIR of 4CT's OR a pair of 6CT's.

The pair of 4's total 220 amp/hours and the 6's 300 amp/hours. It's a pair of one size or the other....... Not one of each.
