2017 REV batteries

[Delco Bobby]

I think I need to replace my house batteries.

This is the OEM. Looks like they may be group 31. Can anyone confirm?

I can get this exact battery in Delaware for $249 each which is much less than many web stores and Amazon.

However, there are local shops that sell InterState and DEKA. I am leaning towards the Interstate from past experience with them and convenience. I haven’t figured out the Interstate equivalent yet. Takes me awhile to mentally focus.

Comments anyone?

I like Interstate.

[Motorhome1]

I just bought interstate. Very pleased

I like Interstate as well, but they have "dumbed down" some of their good deep cycle batteries.

I would also take a look at the Duracell batteries from costco or sams. That is a private label from Dekka/East Penn which is a cheaper version of that exact battery you have in there. If I could buy them I would too.

The last time I needed batteries it was for my Sunseeker and COSTCO didn’t have the group 27 and said they wouldn’t install them. That was 4 years ago.

Today COSTCO told me they don’t have RV batteries and wouldn’t install them anyway. I asked if another COSTCO location might have the batteries. Got brushed off with a NO.

I have read many posts by people who stated they bought their batteries at COSTCO. Either a new policy or the guy is ignorant.

Well, hold that thought. It looks like it is Sams Club, not Costco with the Durcell AGM.

Whew, that is quite a list and it is appreciated.

I am leaning towards the Interstate because there are two Interstate stores that are convenient for me and they remove and install. Now I know what to ask for.

Thanks 😊

Interstate 31M-AGM

I have a Battery Tender that I was considering hooking up to see if it would have a positive affect on the batteries.

I am rather ignorant in these matters so I have questions.

Will the Battery Tender resolve he sulfate issue above and beyond what the stock charger would have done. i think it is a Progressive Dynamics product.

If it is worth a try what is the proper way to hook up the charger to the 2 batteries? Can I do both at the same time?

Just trying to not spend $$ if I don’t have to do so.

Thanks in advance,

Bobby

If you have the batteries removed from the vehicle then you should use an intelligent battery tender to maintain them. However, and Brian C would be authority on this, but I believe that the Progressive Dynamics system you have is a multi-stage intelligent charger so there would be no need to add anything else. There should be a battery management system too that will isolate but also charge your chassis battery.

Yes, what you state above matches my recollection regarding the PD equipment. When home I almost always have the RV plugged in to a dedicated 30 amp circuit. So the PD should be taking care of business.

Grasping at straws here.

not to pry but why do you think you need to replace them? you have a 2017 model year listed so those batteries should only be 2 or 3 years old. and they are group 31 AGM batteries which are a large battery and won't boil off water. you keep them plugged into the PD smart charger. what's the issue? i would expect them to still have quite a life in them? did they get damaged?

They were run down 2 or 3 times. One my fault and twice at the dealer.

They seem to lose their charge quickly. For instance, recently it was on shore power for 3 days. Then we took a 30 minute drive to a shopping center. My wife shopped for about a half hour and I chilled in the REV. All was fine until the water pump ran or the steps operated. Then we had blinking lights. That usually happens when the batteries are getting low. Only some of the lights were on while I was waiting, nothing else.

I am open to comments if I am interpreting this wrong. With winter coming the batteries will discharge quicker.

Replace them.

Just go all out...replace the charge module with a lithium charge wizard and put a lithium up in there. Just do it!

Was that advice for me?

Will one lithium do the job of two AGM batteries.

I just left the Interstate store near me. They said Interstate doesn’t make a group 41 AGM deep cycle.

Quoted me $403 each for Enersys battery plus installation and tax. That is approaching lithium price.

Never heard of a Group 41. You mean a Group 31. This is the link I sent you a few days ago for an Interstate Group 31. This battery or equivalent should only cost you ~$250-$270

Fat fingers. Group 31.

I had your list in my hand.

Interstate Group 31 AGM RV Battery

[Delco Bobby]

I did a Google search for the 31M-AGM but only saw them at Interstate stores and dealers.

I didn't see any Interstate group 31 AGM batteries in the price range you found.

BTW, after I left the store near my home I drove down to the company store in Delaware. The man laughed when I told him what happened. Then he put his hand on the battery we are discussing. Retail price is about $350 each. Installation is half the price of the PA location and no sales tax.
