How Long Should A Travel Trailer Battery Last

A battery’s lifespan is determined by a number of factors, including the quality of the battery and how it is used. That said, a good rule of thumb for estimating the lifespan of your battery is to divide its amp-hour rating by 20.

The problem with this estimate is that it does not take into account how you use your trailer and what type of battery you have. For example, if you use your trailer in cold weather or if you use it to power appliances like an air conditioner, then your mileage will be less than what this estimate would predict.
