Battery nearly dead after 6.5 hours
On 11-3 we had left our camp site after being set up for three weeks. 6.5 hours later the battery seemed to be about dead. When we pulled in to a campground for an overnight, stay, prior to hooking up to shore power, I ran the water pump after using the bathroom and it seemed weak. It was cool out ( 50 degrees) so I kicked on the furnace to take the chill off and it would not come on. Checked the panel and battery showed empty. All I was running while on the road was the refrigerator and the co/lp detector.
Trailer was picked up new on 6-30 and is always on shore power unless we are towing. I have noticed the co/lp detector would intermittently beep since day one when not on shore power. Looked it up and literature says low battery alarm. I just figured the detector was no good and was going to get it replaced under warranty.
When I got home I checked the battery on shore power and it was reading about 13.6 which would indicate the converter is charging it. Disconnected the shore power and ran the front stabilizers down about half way and checked the voltage. It dropped to 11.6 volts that fast and did not rebound.
Apparently the Interstate deep cycle battery (which I am not fond of) is no good. I was also under the impression the TV would maintain the charge while driving but I guess this is not true (2000 Ford Superduty 250) Checked the voltage hooked up and running the TV and it did not increase on this TT or my old TT which I still have. Voltage on the Prodigy brake control was showing 14.2 while running and the old TT which has been sitting for almost a month not connected was 12.6 volts before and after hooking up to it.
Guess i will take the Interstate to a dealer and let them load test it and replace it of no good. Thinking of taking the battery out of the old TT which I bought about 8 months ago and putting it in the Flagstaff, both batteries have the same capacity.
