How often do you replace the fifth-wheel dual batteries.
This will be the fourth yr for out camper. In previous campers I was never able to get more that 2 yrs before I replaced the original dealer batteries.

What is the go to battery for a fifth-wheel?

Lifespan depends on the battery and technology. 5 to 6 years is typical for a well cared for battery. Some go longer. Some last shorter. An electrolyte tester is the best way to determine the health of a battery. AGM and maintenance free batteries are difficult to test.

How you use the battery, care for the battery, type of converter/charger, will all make a difference on battery life.

I purchased my current FW new 8/15/2012, at which time a single Interstate RV/Marine battery was installed. It is still in great shape, works like new. I only had to add water one time, after using a different charger, while battery was stored for Winter. That was five years ago, and water in battery is right where it should be last week, when I installed it back in my FW.

Wet cell batteries typically will go 5 to 6 years if you do not abuse them and maintain them properly.

Most FLA or AGM batteries have shortened lifespans due to over discharge, lack of full and complete regular charging or poor maintenance. The stock converter chargers in many RV's don't do a great job getting batteries to 100% and many don't do equalization charges. In addition the standard battery monitors give poor information as to state of charge so you are basically guessing leading to the batteries easily becoming discharged too low.

If you want a battery that will last many years go with lithium and also install a true shunt based battery monitor.

I use 2 Trojan T-105’s and they perform well for 6 to 7 years if treated properly and you have a good converter.

I replace at 4 1/2 to 5 years. Just don't want a problem away from home.

Any of the batteries we received from the dealer were 12 volt car, or at best a so called hybrid RV battery. In either case they just can't deal with being drawn down time and again if you do lots of RVing off the power grid. If you mostly camp hooked up to a power pedestal any type of battery would suffice. Since we most often attempt to boondock or drycamp we found golfcart batteries give more bang for the buck. We purchase our GC2 6 volt batteries from Samsclub, we use a smart charging converter or inverter charger to keep them happy.

10 years on my 4x Costco GC2. Might be trading them early for a home built LFP later this year.

I only expected the included with purchase battery to get me home [emoticon]
