New Battery Suggestion

The battery in my TT is defective and I need to replace it. The current one is a DP24MF. Should I replace it with another DP? Or is it worth it to go with a deep cycle DC? Given the size of the carrier and the space, I think I cannot go with a larger battery.

Yes you should replace it with a true deep cycle battery but you also need to figure out your anticipated load and size it accordingly.
Because the container is a certain size that does not mean it has to stay that size. I went from a 75AH to a 150AH AGM battery with a larger battery box.
You do need to do your home work Deep Cycle Battery FAQ and Car and Deep Cycle Battery FAQ, Battery Manufacturers and Brand Names List, and

Thanks for the links. There is a lot of useful information there. In fact, there is almost too much information there. I will enjoy reading them as I have already skimmed through them.

"Anticipated load and size accordingly". Is that contained in the articles? Not certain how I do that. My TT is small, at 17' plus a slide out. My requirements should not be low as I have converted almost completely to LED leaving only TV and DVD, plus perhaps the heater blower and gas igniter when it is cold. I suspect that I will spend a few nights now and then without full hookups, but have not so far.

With the design and setup of my TT, there does not seem to be enough room between the gas tanks and the trailer for anything larger than the current size battery holder, but I will check again.

I will second the "Go with the Deep Cycle" the price should not be much different,

Both batteries are roughly 75 amp hours, (I think a Group 24 is actually 73 but this varies a bit between manufacturers so "About 75" NOTE this is the 20 hour method NOT the wal-mart method)

But the difference is with a DEEP CYCLE you can use about half of that, With other types, much less.

If you use battery power a lot... Consider adding an 2nd battery box, and perhaps repalcing the existing one with one a bit taller, and going with two Golf Car batteries in series, they are six volt each, 230 amp hour put 'em in series they are 12 volt 230 amp hour, again you can use half. Which is more power than your Group 24 holds.

Pound for pound most all batteries hold the same amount of electricity, but DEEP cycle you can safely ue more of it.

Also, you may wish to do a converter upgrade. I will list just 4

Magnetek 6300.. Upgrade

Parallex 7300.. You should consider upgrade
Parallex 7300T, Minimum that I consider acceptable

Progressive Dynamics 9200 (And a long list of competitors) Very hard to find one that would be considered an upgrade, This is the top of the list.

On the first 3, you can upgrade JUST the electronics without replacing the distribution panel.
Home is where I park it!
