We've been experiencing lack of 12 volt ability to raise/lower our window shade, and extending/retracting the auto awning, waiting several minutes and several attempts to operate them.

The 2 x 6 volt interstate deep cycle's are about 5 years old, their specific gravity are about 1275-1300 in the green zone, and showing 12.6 average when taking a reading, but fail to provide ample voltage when needed as mentioned above. No apparent issue to operate the Norcold 12 volt function, water pump on occasion, etc.

I am of the opinion that the Xantrex inverter/converter/charger should be providing 12 volt when we are connected to shore power, but it appears that not to be the case, anyone have imput on this?

In doing a search here it appears people have good results with BJ's, Walmart and Costco deep cycle golf cart batt's.

Where should I look to pick up a decent deal on a couple of deep cycle batteries? Thanks.

If I were you I would be checking out why your converter is not charging your batterys while plugged in before just going and buying batterys

Before doing any replacement, locate where you are loosing power from the charger. You should be getting normally over 13 volts to the batteries. It could be just dirty connnections on the batteries.

New batteries won't help much until the charger is fixed. Buy a $5 DVM and post the battery voltage. Then clean and maintain the batteries and have them load tested.

Check out the Xantrex inverter/converter/charger "control panel". Read the manual for how to set it up. If you don't have a manual you can download it.
They even have a video showing how it works and how to set it up.

Batteries & connections are clean, acid level is correct and maintained, voltage when charger is on is 13.+ volts, when off it's 12.6 approx. It's only when putting a load on there is insufficient voltage apparently. I do have a DVM, that's how I posted voltage in my OP.
I will be picking up a Load Tester today, will than do a Load test and proceed from there. Thanks everyone.

Why are some of our members so nasty. If you can't say something constructive or at least nice, you should keep your "Your poor thing" to yourself

I purchased my 6 volters from Costco for about $80 each.
What happens when running on shore power? Does it work properly? If yes, there is a bad connection in the system. Could be around fuses or circuit breakers controlling the defective items.
