Introduction
When you’re looking for a travel trailer, one of the things you need to consider is what size battery you need. Travel trailers come in all shapes and sizes, and so do batteries. The size of your battery will depend on the size and weight of your trailer, as well as how many amenities it has.
If you’re not sure what size battery you need, here are some things to consider:
-The length of your trip: If you’re only going on a weekend trip, you won’t need as big of a battery as if you’re going on a week-long trip.
-The number of people in your party: The more people in your party, the more power you’ll need.
-The type of camping you’re doing: If you’re doing “roughing it” style camping, then you won’t need as many amenities and therefore won’t need as big of a battery. However, if you want to be able to use all the amenities in your trailer (lights, air conditioner, etc.), then you’ll need a bigger battery.
Once you know how long you’ll be gone and what types of camping you want to do, then you can start looking at different battery options. Here are some things to keep in mind when choosing a travel trailer battery:
-Flooded Lead Acid Battery: These are the most common type of batteries used in RVs and travel trailers. They are typically less expensive than other types of batteries, but they require more maintenance. Flooded lead acid batteries also have a shorter lifespan than other types (about 3-5 years).
-Lithium Iron Phosphate Battery: These batteries are more expensive than flooded lead acid batteries, but they require less maintenance and have a longer lifespan (about 10 years). Lithium iron phosphate batteries are also lighter weight, making them ideal for RVs and travel trailers that are light on amenities.
-Absorbed Glass Mat Battery: These batteries are similar to flooded lead acid batteries in terms of price and maintenance, but they have a slightly longer lifespan (about 5 years). Absorbed glass mat batteries are also good for RVs and travel trailers that have lots of electrical devices because they can handle multiple draws without being damaged.
Battery Types
Batteries are an essential part of any travel trailer. They provide power for the lights, water pump, and other appliances. There are three main types of batteries: lead-acid, gel, and absorbed glass mat (AGM). Lead-acid batteries are the most common and most affordable. Gel batteries are more expensive but offer a longer lifespan. AGM batteries are the most expensive but require the least maintenance.
Lead-Acid Batteries
Lead-acid batteries are the most common type of RV battery, and they come in two varieties: flooded lead-acid (FLA) and sealed lead-acid (SLA). FLA batteries require regular maintenance, such as adding water to the cells, while SLA batteries are maintenance-free. Both types of lead-acid batteries are reasonably priced and have a relatively long life span, making them a good choice for RVers who don’t want to spend a lot of money on batteries.
Lithium-Ion Batteries
Lithium-ion batteries are one of the most popular types of batteries on the market today, and for good reason. They boast a number of advantages over other types of batteries, including a longer lifespan, lighter weight, and higher capacity.
One of the biggest advantages of lithium-ion batteries is that they don’t suffer from the so-called “memory effect” that can plague other types of batteries. The memory effect occurs when a battery is only partially discharged before being recharged, and it can permanently reduce the capacity of the battery. Lithium-ion batteries are not affected by this, which means they will retain their full capacity even if you only discharge them partially before recharging them.
Another big advantage of lithium-ion batteries is their weight. These batteries are much lighter than other types of batteries with comparable capacities, making them ideal for use in portable devices and vehicles.
Bottom line: If you’re looking for a high-quality battery that won’t let you down, lithium-ion is the way to go.
Battery Capacity
The size of the battery you’ll need is affected by the amount of electricity you use while dry camping and the number of days you’ll be dry camping. To estimate your power use, figure out the watt-hours of each appliance you use and add them up. Watt-hours (Wh) = volts (V) x amp-hours (Ah).
Amp-Hours (AH)
Amp-hours, or AH, is a rating that tells you how much power a battery can hold. The higher the number, the longer the battery will last. For example, a battery with an AH rating of 100 will last twice as long as a battery with an AH rating of 50.
You’ll usually see amp-hour ratings listed as 20AH, 30AH, 40AH, and so on. But what if you see a battery with a higher number like 100AH or 200AH? That just means the battery can hold more power and will last even longer.
Watt-Hours (WH)
Watt-hours, abbreviated Wh, is the most common way to describe the capacity of a battery. The formula to find watt-hours is simple: multiply the voltage by the amp hours. For example, a battery that is rated at 100ah @ 12v has a capacity of 1200 watt hours (12v x 100ah = 1200wh).
Most travel trailers have a 12-volt system, so you will typically see batteries advertised as either 12 volt or 6 volt. The difference between these two types of batteries is simply the number of cells in the battery. A 12 volt battery has six cells arranged in a series, while a 6 volt battery has three cells arranged in a series. The voltage of the battery is determined by the number of cells in the battery; each cell has a voltage of 2.1 volts. Thus, a 12 volt battery has a total voltage of 12.6 volts (6 x 2.1v = 12.6v), and a 6 volt battery has a total voltage of 7.2 volts (3 x 2.1v = 7.2v).
The capacity of a battery is also affected by its temperature; as temperatures increase, the capacity of the battery decreases. For this reason, it is important to consider both the amp hours and the temperature rating when choosing a travel trailer battery.
Battery Life
There are a few things you need to take into account when determining what size battery you need for your travel trailer. The first is amp hours (AH). This is a rating that tells you how much electricity the battery can hold.
The second is cold cranking amps (CCA). This number tells you how much power the battery can provide in cold weather. You’ll want a higher number here if you plan on doing any camping in cold weather.
Finally, you need to take into account the size of your RV. Smaller RVs will need smaller batteries, while larger RVs will need larger batteries.
As a general rule of thumb, you should get a battery with at least 50 AH and 400 CCA. This will be enough to power most small to medium-sized RVs in most conditions.
Conclusion
The size of the battery you need for your travel trailer depends on a number of factors, including the type of trailer you have, the number of appliances and electronics you plan to use, and how often you plan to use them. Choosing the right size battery will help ensure that you have enough power to meet your needs and that your battery lasts for as long as possible.
