6v golf cart batteries at Costco

I saw 204AH 6v batteries there for $85 yesterday. Lead acid.

Does this seem like a reasonable approach for house batt setup?

If putting inside van, is this a bad idea? Do we have to put non vented AGM inside?

Well, looking at the recent posts from the DIY'ers/RV'ers here, you either need to but the lead acid batteries in a vented box, or eliminate your smoke and CO2 alarms.
Putting them under the Sprinter, in a vented box, or using the Auxiliary battery tray in the engine compartment seems like a better idea to me.

The Costco 6 volt blocks are good quality in these parts. We have three electric Club Cars and the Costco blocks hold-up well over time....lots of lead and plenty of space above the plates for electrolyte, like the Trojan 6V blocks.

Sailquick is correct about the possibility of hydrogen off-gassing (H2 evolution) making your CO alarm nuisance-trip. This would not normally be the case on float; mostly during heavy charge or heavy discharge periods. Although, I doubt an RV-mounted solar system charger could make battery electrolyte boil, like a larger AC-powered rectifier.

BTW, valve-regulated (recombination) lead acid batteries do vent hydrogen gas but just not as much or as often at just flooded lead acid cells.

I have held them in my hands, they are a good price but no where near the weight as a Trojan or Deka [less lead] After the issues I have had with flooded batteries I would recommend AGM style if you can afford them, especially inside the van, no gassing and if mounted under the van alot less hassle to maintain, basically null. Flooded batteries need close regular inspection, and leak.

Thanks for the insight.

Costco listed these as 63lbs.

I looked at the Costco 6v Golf cart batteries a couple of days ago and they sure looked like one of the Deka batteries: same lid covers, same dimensions, similar weight, etc.

It might be worth throwing these on the scale at Costco, as they may have received a non valid weight to post on the placard.

I love my Costco batteries, coming up on 2 years, with zero issues, hose them down occasionally for corrosion, and the solar keeps them topped up, but I have only had to fill them once in that time. And I run TVs and furnaces and lights all the time, even an AppleTV via the inverter. Thinking about adding a 2000 watt inverter to reheat with the microwave or at least to Kuerig some coffee in the morning w/o having to crank up the genny in the rest area, or casino parking lot. That's just rude.

I ended up getting 2 golf cart batteries at Costco in OR. They are Interstate batteries with full Interstate labels. $87 ea.

Costco recently has switched from Kirkland Signature to Interstate batteries. Their Marine/RV deep cycle batteries seem to be heavier than their car batteries. They still had a CCA spec on them so am guessing not AGM. Would be curious to see if anyone else know what they really are?

If it says 'Marine' anywhere on the battery it is probably a starting/deep cycle hybrid (if there really is such a thing.) It is in all likelihood not a true deep-cycle battery.
