Brand new batteries going dead

This may have been addressed before, but I can't find anything:

our 2007 34 DDS batteries are draining completely. We just put brand new batteries in both coach and chassis. Something is draining them and we cannot figure out what/why. Since we are unfamiliar with how the Xantrex works, we don't know if that is causing it or not. We need to get this fixed. Can someone give us some advice on what to look for? We are at a loss!

Thank you!

maybe you could describe the conditions surrounding the situation.

Is this happening in storage over weeks?
Is this happening overnight from 8pm to 8am?
Are the batteries receiving a full charge, and you've confirmed this how?
Did you make any change to the battery configuation? ie 12 volt to 6 volts.
Are they wired properly?
Do you have an inverter, and if so, are you leaving it turned on?

It happens over night. Went from 2 12 volts to 4 6 volt on the chassis. Coach batteries are 12 volt. Inverter is on all night..

Went to the Internet to get wiring Diagram and also followed diagram on coach.

Why would both Chassis and coach batteries be gong dead? Why would they be interconnected?

Ladytj, welcome to the Alpine family and IRV2. The way your coach is set up, when plugged into shore power the Xantrex inverter/charger should charge the house batteries, and then the chassis batteries. There are a couple of things that will affect if that will work.

1) Are you plugged into shore power or is the generator running, do you hear the ATS clunk about 39 seconds after you connect either shore power or start the genny?
2) Are the disconnect switches turned on?
3) Is charging enabled on the Xantrex SCP?

If all 3 above are true you should be charging the battery banks. You could also have a solar charger that could be charging the house batteries.

If the above does not resolve your issues, reply with the following info

1) Is your coach a limited or Apex?
2) Are you connected to shore power?
3) Is charging enabled on your Xantrex?
4) Do you have solar panels on the roof?
5) When did this start happening and what did you do last on the coach?
6) Who installed the batteries and has charging ever worked after the new batteries were installed?
7) Is there anything else happening with the coach we should know about?
8) When plugged into shore power does everything in the coach operate, like the lights above the table, if so disconnect shore power, do not start the genny and tell me if you get 110 AC at the plugs nearest to the sink?
9) Do you have a digital voltmeter, if so measure the voltage at both the house and the chassis batteries?

Dave

Your coach was not built with 2 12v house batteries, it did have 2 12 volt batteries wired in parallel chassis batteries and 4 6 volt deep Cycle batteries wired in series/parallel giving you 12 volts with doubled the amp hours.

There is an interconnect switch up on the dash board, that must be held closed to work properly, it is only for emergency jumping the 2 battery banks together. The relay that switch controls could be defective, but that is not the cause of your problems.

Thank you, Dave. We will go through your list and see if we can answer these questions. Will get back with you to confirm.

Well, we MAY have figured our problem out. Apparently when new batteries are installed, the Xantrex needs to be reset and reconnected to the device (I'm probably saying this wrong). Anyway, we have the batteries charged and reset the Xantrex system. Will test tomorrow to see if everything is working properly.

Unfortunately, we had never had one of these systems before, so didn't know it all had to be reset...

As a side note, being in Wyoming, we found a place in Colorado Springs, CO (closest location) that is an authorized Xantrex Service Center, just in case!!

Brand new batteries going dead

Since you have made change to the battery bank you also need to be sure the Xantrex is programmed to the correct parameters. All batteries have a specific capacity expressed in volts and AH (amp hours). When you have two 6 volt wet cell batteries in series the voltage doubles, but the AH stays the same. For example if you have two 6 Volt, 200 AH batteries in series you then have a battery bank of 12 volts, 200 AH. If you then add another two 6 volt, 200 AH batteries in series and place them in parallel to the first set you have a four battery bank of 12 volts 400 AH. To properly charge, the Xantrex must be set to reflect this. Program it as wet cell, (or whatever type batteries you have) 12 volt, 400 AH. That way the Xantrex will properly step through the appropriate charge stages. You will have to adjust the numbers above to whatever capacity your batteries are.

If you do not have a manual go to the Xantrex web site and get the right one, go to the set up section and run through it. I think I caught all the steps, but this is from memory.

By the way, most competent RV service centers can service Xantrex systems, if you don't want to, you do not have to go all the way to Colorado Springs to get the Xantrex serviced.

Great news! After resetting the Xantrex, everything works!! This coach has certainly been a learning experience! Even though it's our 5th RV, most everything is different on this one!! We'll keep getting things figured out!!

Dave, you're awesome!! Thanks again for the information!

The coach originally came with 6-6V or 8-6V house batteries, all 220 amp-hour. If you replaced prior batteries with 4-6V 220 amp-hour batteries, you will probably be a little under capacity when dry camping and need to run the gen a bit more. If you put in larger 6V batteries, you are probably fine.
