What is a travel trailer battery?

The travel trailer battery is the power source for the systems that control the taillights, interior loads, electric wheel brakes, marker lights and all accessories on the dashboard.

Travel trailer batteries are typically the same as “RV Lithium Batteries” and provide 12 volts DC to all components of the trailer. Almost all components in the trailer run on 12 volts. Shore power is typically 120-volt alternating current (AC) power for charging the RV battery. The electricity is convert to 12 volts, which can generate power for the appliances such as refrigerators, microwaves, etc.

Types of travel trailer batteries

Value Regulated Lead Acid (VRLA) Batteries.

This type of electrolyte is suspended in a gel or fiberglass mat. When gel acid is used, the battery is called a gel battery.

Absorbed Glass Mat (AGM) battery

A fiber mat is sandwiched between the plates of this battery, which is more expensive than a regular deep-cycle battery. You can charge them like lead-acid batteries, but they’re leak-proof, can’t freeze at low temperatures, and are mostly maintenance-free.

Lithium-ion battery

This type of battery used to lack deep-cycle applications, but more is now being produced for this purpose. Lithium-ion batteries have an internal management system for maximum safety. they provide more power than many other types of batteries and they are lighter and more compact than lead-acid batteries. Also 4 times lifespan than normal lead acid batteries.

What is the best travel trailer batteries?

With the popularization and maturity of lithium battery technology, lithium battery deserves to be the best travel trailer battery. The following details the reasons why we are updating lead-acid batteries to lithium batteries.

  • Environmentally Friendly
  • Lightweight And Compact
  • High Energy Density
  • Low Maintenance
  • Long Lifespan
  • Low Self-discharge Rate

How long does a battery last on a travel trailer?

Obviously, when someone asks me about how long do travel trailer battery last, we should distinguish between lead-acid batteries and lithium-ion batteries, because the lifespan of the two is very different, which is determined by the internal chemistry of the two. Below I talk about the lifespan of lithium and lead acid batteries separately.

Lifespan Of Lead Acid Travel Trailer Batteries

The above diagram is the cycle life of Trojan Deep-Cycle Gel Batteries, the lifespan is 500times@80%DOD.That means if you charge/discharge your travel trailer one time per day, your travel trailer battery can last 500/365=1.36years. And if you charge/discharge your travel trailer one time per two day, your travel trailer battery can last 500/365*2=2.72years.

Lifespan Of Lithium Travel Trailer Batteries

The above diagram is the cycle life of ELB Deep Cycle lithium Batteries, the lifespan is more than 6000times@80%DOD.That means if you charge/discharge your travel trailer one time per day, your travel trailer battery can last 7000/365=16.43years. And if you charge/discharge your travel trailer one time per two day, your travel trailer lithium battery can last 7000/365*2=32.86years.

In summary,

Travel Trailer Lead-acid battery can last 1-3years

Travel Trailer Lithium battery can last 10-20 years.

How to prolong the lifespan of travel trailer batteries?

As we all know, Proper maintenance of the battery, and compliance with the principles of battery use, which can greatly extend the life of the battery.

Improper use of the battery will also shorten the life of the battery.

Anyway, here are a few tips to keep in mind to enable your battery last longer.

Charging Tips

  • Regularly Charging. Under normal circumstances, when the battery is too low, there will be a reminder when the battery has no electricity. At this time, you need to replenish the battery in time. Although the battery is too low, it will not lead to a direct safety accident, but excessive use will lead to over time. Damage to the battery structure.

  • Do not overcharge. The inside of the lithium battery cell is also composed of many components. The new battery is fine. If it is used for a long time, the function of which component may decline, so there will be an overcharge safety risk. Generally, Overcharging your travel trailer battery cause damage to it in the long run.
  • Use a suitable charger. Do not charge batteries with inappropriate chargers.

Using Tips

Avoid Completely Draining the Battery

Once the battery indicator on your travel trailer shows that the battery is getting low, proceed straightaway to charge it.

Allowing the battery to completely drain out has an adverse effect on the lifespan of the battery. It could hamper performance.

When the battery is used up, please recharge the battery in time.

Maintenance Tips

The purpose of daily maintenance is to place the lithium battery in a suitable environment, thereby delaying the aging of the battery.

Here is two maintenance tips that we need comply with.

  1. Protect against moisture.
  2. And avoid direct sunlight.
