Battery

Hi my family recently puchaced a 2004 forest river rockwood roo. We are been learning how everything works, but are having trouble with getting the battery to charge. If I use a battery charger it will charge up but when I hook it up to the trailer it drains. If anyone has any helpful tips it would be most appreciated. Thanks Ryan

first, welcome to the "Roo Kroo"!!!

second, there is a Roo section under Expandables. lots of Roo or Shamrock owners there to help. you posted under "Useful Links", which is buried under a lot of other forum sections.
or you can post Tech questions in "General Tech and Repair".
which model of Roo do you have?

a lot of new trailer owners are unaware of the parasitic battery drains in trailers(propane alarm, radio and so on). and they mistakenly think that the tow vehicle will recharge the battery. mostly, it's only a trickle charge.
have you tested the battery and how old is it? don't rely on the monitor panel. they are famous for being inaccurate.

have the battery tested.

I'm not sure what model it is. My Father in law has it and he is not sure how to find out which one it is. There is three slide outs. One in the front, one in the back and one on the side. We are going to have the battrey tested. but we thought that having it plugged into the house that it would charge it but its not. Ill check out the useful links. Thanks for your help. Ryan

when you say "slide outs", you must mean "bunk ends". the Roo is a hybrid with canvas bunk ends. a slide out is a section of the wall that mechanically slides out.
the bunk ends drop down like a tailgate on a pickup.

if it has the 3 canvas bunk ends, 1 on each end and one on the driver's side, it's a 183 or 233. should be a sticker, by the door, with the model number.
if it has just two canvas bunk ends and a slide out, it could be a number of different models.

with that old of a trailer, the converter/charger may be bad. need to have that tested if the battery is good.

You may have some bad cells in that battery. If you haven't opened it up yet to check the fluids, then do that carefully, and look at the plates in all 6 holes. If you can see exposed metal fins in any of the cells, that battery is more than likely fried. My 08 has a WFCO 3 stage converter that charges the battery when plugged in, or when driving, hooked to the truck. Good luck, Randy

Always wear eye protection when messing with a battery.......better yet use a full face shield.

I have an 06 21SS Roo. Sounds like a bad battery or if I leave my battery connected for over a week the monitor inside makes it dead. So I disconnect it when Im not using it.

It sounds like there is little or no charge from your converter/charger to your battery when plugged in. While plugged into shore power, try checking where the leads connect to the battery from the charger with a voltage meter. You should have about 13 amps flowing from the converter/charger to the battery. If you have low or no flow, you need to focus on the converter/charger.

Question

This is a timely topic. Looks the battery in my '06 sv 264 is about to go. I had the power unhooked for 3 weeks and when I went to open the slide it was almost dead. Plugged it back in and the battery charged ok and opened the slide with no problem. But since it's the original, I should shop around for a replacement.

What is best battery to get? I want to get the max power rating since we'll be doing some dry camping from time to time.

if you want to do dry camping, having two 6v golf cart batteries or two 12v deep cycle RV batteries, are the way to go. we can go 4-5 days easily without a recharge.
the 6v are the best option but more expensive.
