Still researching 6 volt house batteries

Still researching 6 volt house batteries. Looking at Trojan T105 and T125. Also Carquest has a golf cart battery at around the same price and rating for around $140 each. Our bay is limited to 17.5 inches in each direction by 11 inches high. Our problem at the moment is our 4 year old Interstate batteries discharge overnight. When the coach is parked, we keep it on a battery charger for two hours every day and even this discharges quickly. We have had this problem analyzed by two different mechanics and determined a 2 amp per hour draw (parasitic?) Could this be our current batteries, would changing the batteries help? We have been told Interstate are not good 6 volt batteries. Our supplier told us no 6 volt batteries are guaranteed. We are confused.

I don't believe that Interstate can't make a good 6 volt battery. They are one of the favorites on this forum and others. You can't draw 2 amps from any battery and have it keep a charge for long. It's a LOT more than a "parasitic" drain. Here's what I would do. I would break the problem down and try to find WHERE the drain is happening. You should be able to do this by using an ammeter. First determine with the ammeter what the drain current is. Verify that it is 2 amps. Then, with the ammeter still in the circuit, start pulling fuses one at a time, noting which fuse, when pulled, drops the meter reading significantly. It may be more than one circuit that is draining, so check all the fuses. When you have found the one or two fuses that affect the reading, you will know what appliances are responsible (assuming your fuses are labeled). Any competent tech should be able to do the same thing, but, as you found out, they don't always come up with complete answers. You may also have weak batteries or batteries without enough water in them.

Full Monte is right on for researching your drain. Interstate sells a bazillion batteries for RV use so blaming them is silly. Until you find the drain your problem will continue with new batteries as well.

First of all, Interstate doesn't make batteries - they are just a brand name for marketing & distribution. Last I knew, US Battery supplied 6v golf cart batteries for Interstate and they make as good a GC battery as anyone. Carquest is also just a private label for marketing - they buy their batteries from a battery manufacturer too. I don't know who supplies Carquest stores.

When comparing 6v GC2 batteries, compare the rated Amp-Hours or the weight or both. More AH = more capacity, and more weight means more lead inside and that relates directly to more capacity and better construction. A T105 weighs 62 lbs and produces 225 AH - use that as the standard. A T125 (same physical size) weighs 66 lbs produces 240 AH - that's the premium end for the GC2 size you need. If you can find another, less expensive battery with the same specs, it's probably ok, though Trojan remains the gold standard for golf cart batteries.

If you don't do a lot of boon docking, Sam's has a Duracell GC-2 w/205 amp hrs for $84.52 + tax. They sure look like the interstate version...
Have you checked for a bad cell with a hydrometer? They're a pretty cheap battery health and troubleshooting tool.
