How many batteries

Hello we have just picked up a 292bhs prime time lacrosse and im concerned that the dealer got cheap and gave us just one battery.

In fact they gave us a dual purpose battery not even a deep cycle battery it still is a marine rv style.

if the dealer truly did the minimum then we will deal with that and move on to dual batteries.

Our issue happened on our first trip, the single battery didnt even last much more then 2 hours total, and thats not even using anything besides the basic lights and initial setup.

One battery from the factory is pretty standard, though the battery box usually has room for two. You should have gotten a little more than 2 hours. Check the breaker for the converter. Shop techs will often turn it off while doing installs, etc., and forget to turn it back on. Also, if you have slides wait until plugged in to extend them - thet are big drain on the batteries.

How bad will the slide kill the battery? we went camping and had no power, this along wit the power awning and jacks i thought we would have got atleast two batteries, it doesnt seem like much bigger of hassle for two.

It's very uncommon to get two batteries unless you specify and then you'll pay for additional including extra wiring.
Did you disconnect battery since delivery?
If your unit isn't plugged in while not in use parasitic draws will run battery dead unless disconnected.

It isn't the hastle the manufacturer/dealer is worried about when installing a second battery, it's the cost. Most come with one battery and you have to specify that you want a second, at an extra charge of course. Make sure you have a shut-off switch installed too, if there isn't one already there, or your battery will drain when not hooked up to shore power. Also, make sure you match the batteries up for amps and age or one will go bad faster than the other. They should both be deep cycle batteries on your TT. I don't understand why they would have a deep cycle/starting battey in it. I would be calling them about it and wanting it changed out.

It is most likely the battery you have was:

1) not completely charged when you got to the campsite
2) Used to power high draw items (slides, heater, jacks, water pump)
3) Not monitored for usage (minimize battery use).

While 2 hours is really low (normally), it could be right if you have no idea how much juice you had at the start and what you were using. The more amps you try to suck out at once, the less able to do so any battery is.

Make sure your fridge is not on climate control and your light use is minimal. (Each bulb pulls 1.2 amps for example).

Here is a chart that shows how trying to use a lot of power at once will actually reduce the ability of the battery to deliver it. Multiple batteries allow the demands to be spread across the batteries so the individual generation requirement extends the over all life of the battery bank.

We brought home the trailer friday night and it was immediately plugged in until we unhooked sunday night and left, the campsite was 45 minutes away and a little after 2 hours all the lights had dimmed etc.

The initial setup with jacks and tongue and slide all was performed with the trailer connected to the truck.

I have been talking with Rick @ Prime Time and he is checking to see if we should have gotten two batteries.

The dual purpose battery is a definitive issue that will have to be fixed as we want a deep cycle.
