What make/model of house batteries?
Just in case there's a difference between different Georgetown motorhomes.......
Can anyone tell me the make and model of the "house batteries" underneath the entrance steps of a 2010 330TS? My unit is at the dealer's right now, so I can't check, but the dealer says they need to be replaced (manufactured June 2008).
Original equipment was two 12 volt batteries, although I know some members have switched over to 6 volt for various reasons.
I'd just like to know a price comparison, and if possible, does anyone know the price here in Canada, specifically Ontario.
Thanks

We just replaced ours at walmart with their deep cycle battery. You might want to call them for a price comparison. Our batteries weren't lasting the night to run the furnace - and at minus 10-20 we needed heat. New batteries not only lasted the night, but several nights.

I would expect a new 2012 rig to have batteries no older than 2011. I think you're getting your clock cleaned!
When we got our '02 in '09, the house battery was shot, but I expected that. Even though the battery box was big enough for two batteries, it only had one installed. I biought two new deep-cycle RV/Marine batteries from Costco, along with the necessary battery cables to hook them in parallel. I think they were about $70 apiece.
They're still working fine.

I would take the unit to a place that has a load tester and have the batteries checked before replacing them.
Like Frank said "I think your getting your clock cleaned."

I have the exact same year and model as you (2010 330TS) and have had no problems so far with the batteries. Curious, were you having it serviced because of battery issues? If not, did you notice anything wrong with the batteries?

We use the Group 27 Marine deep cycle from Walmart. Johnson Controls manufactures this battery and has very good ratings.
I have 5 of these on our boat.
120Ah for a 12V
Replacing a battery after 4 years is expected. You can get them to last 6 years, but that's with proper charging and never letting them drop below 50% charge, usually 12.2V when testing without load.
Hope this helps.

My 2011 327DS came with two batteries with no readily visible manufacturer markings on them. From their size, I expect that they're around 110AH batteries. I've been having problems with an overnight dry camp with the furnace running and had a long talk with the dealer about the problem.
It turns out that the dealer has no way to load test the batteries. They have a tester for the chassis battery but not the house battery! I built my own tester and discovered that the battery has less than a 50AH capacity, I just picked up a hydrometer which shows that the cells are "fully charged" after recharging the battery with my "smart" battery charger. This agrees with what the dealer found when they checked them.
Tomorrow is another load test for the batteries. This time, I'll get individual cell specific gravity measurements in addition to the voltage values taken as the battery discharges. I've already notified the dealer about the problem and his response was that the second battery is probably just as bad and that they'll have to replace them before the factory warranty expires. I'm planning on donating the finished tester to the dealer so they can test batteries for other owners.
In some respects, I'm not surprised about the batteries. When we first looked at the motor home, the sales rep tried to start the generator using the house batteries and couldn't. This means that they had been discharged for an unknown period of time and probably suffered from sulfation. When I had a wiring short in the jack system, it also discharged the batteries and they were left in that state for another couple of weeks until the short was discovered. I suspect that the two full discharges with extended periods discharged have a lot to do with the battery's current capacity.
My next question is about the converter that comes with the motor home. This is the primary mechanism for recharging the batteries and I don't recall if it's really designed to charge the batteries or provide power to run all of the DC stuff. Next time I'm at the motor home I'll have to pull out the documentation for it and see what it says.

Ours had a no name brand of batteries. When one of them blow up. John Armstrong had Ron Hoover RV put in a new set and these are brand name. The coach is in storage so I can't tell you the name. But do seem to hold a charge much better.

That's true,
Once a battery has been allowed to go dead (wet cell) it's live and capacity drops considerably. 2 more times and its toast.
When replacing batteries in a bank, it's best to replace them all with the same size and brand and manufacture date.

Here's my earlier post with the new battery setup I put under the step on my Georgetown. Some good information from Lou in this thread too about his setup in his 5th wheel.

Here is the decal on one of my original house batteries on my 330ts.

Interstate Battery comes in most GT's ,4 6volt cost more but last longer life and give longer amp.hours

Iochsa's photo looks like the one on my batteries. The one I had out has been returned and the dealer is planning on replacing both of them under warranty. I'd like to use 4x6v but FR didn't see fit to make a battery box that filled the compartment and would have provided space for the second set of batteries. Even if the box was big enough; the supplied + power cable wouldn't reach to the other set of battery's positive terminal.
I stopped at a local Crown battery dealer and they checked the battery and said that there were a couple of cells with sulfation damage; what I expected from the known usage of the battery. They also showed me their battery that's the same physical size - It weighs 10-20 lbs more than the OE battery. You can draw your own conclusions from that. It costs more than double what's available from other local stores but, using best guess estimates based on "reserve minutes", has 30% more capacity than others. It seems like many other things, you get what you pay for.
I found the definition for calculating "reserve minutes" for a battery. It's the number of minutes that the battery will supply 25A starting at full charge and ending when the battery voltage drops to 10.5V.

The second generation 2012 378 LX has Inteli-Power converter. My early 2112 378 has an other brand. My coach is in storage and I don't remember the brand. When I had my tour of the Georgetown plant I saw they were putting in the Inteli-power. I had put the same one on my fifth wheel so I noticed it. I asked them at Forest River service if my converter could have been the reason that my battery blow up. They checked my converter and told me it was fine and that it had a control on it to make sure it charged the batteries properly.

Wet cell deep cycle batteries don't last long if not properly maintained. I replaced mine after 2 yrs. I PROMISE I'll take better care of them this time.
