Replacement Battery

[Kevin21]

The original battery in our TT has seen its last days. What brand and type is the best replacement.

There are a ton of threads out there on battery setups for boondocking.

But, if you just want a battery for an odd night w/o electricity and not for longer term camping then a deep cycle battery ( not a starting and deep cycle marine battery) will do.

Based on what you want to do a 27 model battery has more reserve power than a 24 and only costs a little more. It will help if you get into a no electric situation and need to run your furnace.

Brand and source are important as you want to have warranty service.

Be aware that most deep cycle batteries only come with a one year warranty.

Each battery mfr has there own warranty replacement time frames. Below is the Trojan Warranty information. After the initial replacement time frame the battery is pro-rated for x number of months.

Before you decide on which battery to buy, you need to know if you will be needing power just to supply the TT with 12Volts, or if you plan on using it for overnight stop-overs, or for dry camping. If you just need to replace the battery and no need for overnight or dry camping a regular size 24 Interstate RV/Marine 12VDC, 85Ah battery (or equivalent) will be fine... you still need to check the water level on a regular basis, or you will be replacing the inexpensive one also.

Can you describe how you use your TT. We could recommend a really good batter set, but if all you do is pull the camper from home to a full hookup site, then this would be a waste of money.

For example if you always use full hookups a cheap group 24 dual purpose battery is good enough. all it needs to do is power the emergency breaks and provide a little backup power.

If you boondock a few nights a year, a single group 27 battery might be OK. if you do not need to run the furnace for more than one night and you have all LED lights, and are fairly power conservative.

If you like to be off the grid for days and want to use lots of power, then a multiple 6 volt golf cart battery setup would be much better solution.

So, if you provide a little more info on how you use your camper, I bet we can help select a battery choice.

We have had the TT 5 years and have only boondocked 2 times. Everything is home to a full hookup.

@Mustang65, that Trojan warranty states they will only cover if used in "renewable energy or backup power" installations. That doesn't really strike me as how it is used in a TT application (the batteries in those listed installations don't generally get dragged along our roadways for miles on end, with the attendant vibration etc).
Anyone ever tried to make a warranty claim with Trojan for TT use?

Unless you are planning to change your camping style.

A cheap group 24 dual purpose battery will work fine your needs, such as an Interstate Battery. A dual purpose battery is a cross between a deep cycle battery and a starting battery. These batteries do not have as much of a power capacity as a true deep cycle battery.

The most important thing the battery does for you is activate the trailer's breaks in an emergency disconnect situation.

One of the questions I asked the specialist when I purchased the T-145's was what if one or both go bad... his response was that they would honor the Trojan warranty (even if they were in the TT). Never had any issues, so I have no idea.
