Replace battery advice

I need to replace the six house batteries in my 2014 Dutchstar. Iím thinking about replacing them with 6 Lifeline GPL-6CT batteries (300 amp hours per battery). The width/length of these batteries are the same as my current batteries. But the height of these batteries is 13 inches. I measured the space in my battery tray compartment area - seems there is room for 13Ē high battery. Second, the batteries are 90 pounds each, which is about 25 pounds heavier (per battery) than what I have today.

Any opinions on these batteries? Should I be concerned with the added height or weight? I called Newmar and they said they didnít think the added weight should matter.

Thank you, Dave

Would adding the battery cables impact your fitment...you have probably thought that thru, but thought I would mention it.

Good Luck with your swap out!

Hard to beat Costco for Interstate 6 volt batteries. Less then 100$ a piece with a 3 year replacement free of charge. Have put them in our Essex and numerous other Newmar's. Our 18 LA came with AGM batteries and will have to see how they do in the future.

Lifelines batteries are the finest quality, longest lasting,
and are superior to all other AGM batteries. They cost
more but are worth it. IMHO.
Developed for the military, used in all the high quality
aircraft, boats and rvs, you will not be disappointed.

The question I would be asking is do you plan to switch to Lithium batteries when the technology matures and the prices come down, hopefully in the next 3-4 years?

I installed 8 of these this in my 2018 LA. I had to fabricate a hold down frame and new crossover cables. No regrets much improved capicity. Had Lifelines in my last MH they were still going strong 5 years later.

Remember when disconnecting the cables to remove the POSITIVE first to avoid damage to the inverter. If the ground is removed first the inverter will try to find a ground through the display and cook it from what I've been told.

Lifeline are an excellent battery but pricey. Since we donít do a lot of boondocking I installed 8 Dura Cell agm 6v golf cart batteries from Samís. They are made in the USA by East Penn. They are about $180 each. I have been real happy with them.

AGM Batteries

Dhibe- you are definitely doing the right thing! Three years ago I replaced my 8 Discover AGM batteries (OEM) that only lasted 21 months - What a piece of Chinese Junk! with 8 Lifeline GPL-6CT batteries- about $3,200.

I had used Lifeline in my previous 2 coaches & had great longevity & service from them. In my 2005 MADP they were 9 years old & still going great!

To eliminate your concern about the increased weight, which is correct- I called the battery tray manufacture & talked with them. They said 720# was no problem as the tray is designed for 1,200 # uniform load & they have tested it to well above that weight. I have been running with them for 3 years & over 20,000 miles & the tray is still solid as a rock & operating smoothly.

I have now been able to boondock for up to 3 days without starting the generator.

As the old saying goes- YOU GET WHAT YOU PAY FOR!

Happy Trails

Thank you everyone for comments and suggestions. I talked with battery retailer today - very knowledgeable about RV batteries. He will have Lifeline ship the 6 batteries to a shipper here in Houston. I then go pick them up. Out the door price is just at $400/battery.

Weight ALWAYS matters, if you should worry about the extra weight or not would depend on your current corner weights. As others have said the batteries are quality batteries.

I also installed these Duracell's. A little less amp rating but they're all I need
