battery

Doesn't come with a battery?  Really?

I'm kind of new to this trailer business (two years) and we bought ours used so I'm not real familiar with the program of buying a new unit. But they tell you the battery is extra?
I know they are not shipped with a battery, I'm assuming to do with hazardous materials rules?

I couldn't fathom going with out a battery (but then I have 2 batteries and a new generator).
This one is going to be interesting to hear!

We need the emoticon of the guy eating Pop Corn. 

You absolutely need a battery.  It would border on criminal for the dealer to allow you to drive away without one.  As Podster notes above, in the event the trailer becomes disconnected from the tow vehicle, the battery powers the electric brakes in an attempt to bring the trailer to a stop as quickly as possible (note: it won't be pretty, and the trailer may well end up smashed on its side; but, at least it isn't careening down a hill, gathering speed, heading towards who knows what kind of trouble).

thanks for the replies, but what is the difference between Marine group 24 vs 27, as 2 have mentioned each ?

Generally the higher the group number the bigger the battery.
Bigger is usually better to a point but you have to pay for it and have space to put it.
(and possibly the weight problem)

In a pinch a battery is a battery. But when you are putting money out for the long run you want the right battery for the right job.    Automotive batteries for example have more of cranking amps for starting but do not have a "deep cycle" life.  A deep cycle battery has a deep reserve but not much cranking amps for starting.

One of the experts on here will find you a good link or two for educating yourself about batteries.  If you're like me just keep reading............ eventually some of it sinks in and sticks. 

An addendum to my earlier post: It just goes to show. DON'T BELIEVE EVERYTHING A SALESMAN TELLS YOU.  The more I think about it I can't believe that sales man even said "you don't need a battery".

Originally posted by mesamie I am buying the 2016 Rpod 179 model this week. The dealer informed me it does not come with the battery, it would be extra. He indicated he doesn't use his, but if he did buy one he would get a bigger one than what is provided/sold with the unit. So first question, if I don't plan on dry camping, at least not for a while, do I need a battery, and if NOT, can I use the car battery for basic power ups ? Second, if I should get one, should I get a bigger as he recommended ?

Seriously.. WALK AWAY. Find another dealer. If this is how he operates, you don't want to find out how they might be for service or warranty. Really. You don't.

Find another dealer.
