Batteries for Freightliner Motorhome Chassis

It seems sense that the sort of battery you use would depend on the brand of chassis.

This is not true.

The battery system is not significantly influenced by the chassis.

The mechanism works well and it just needs to keep the battery in place.

Only the quality and lifespan of the battery count when seeking for a replacement, not the brand.

There are some excellent off-brand choices and some subpar models from well-known brands.

In other words, regardless of the brand you choose to purchase, you run the risk of picking a subpar product.

However, there is a method to continue using the Freightliner brand.

The private label for components used by Freightliner is a business named Alliance.

They produce or market two AGM batteries.

One is for the coach, and the other is for the beginning.

These battery choices are the deep cycle model EPM/AE8A31 and the beginning model EPM/AE9A31.

A simple search reveals that Alliance continues to provide batteries for the Freightliner chassis and cars even if that information is dated 2009.

Your chances of finding the ideal battery for your RV with a Freightliner chassis are good given that their website includes three pages of batteries.

How Long Do The Batteries In RV Chassis Last?

Lead-acid batteries, which are often used in general chassis batteries, are known for their extended lifespan.

Some deep cycle batteries have a stated lifespan of six years or more.

Despite the fact that some owners have reported getting 11 years out of their batteries, lead-acid choices do not last as long.

A lead-acid battery typically has a lifespan of 5 to 6 years.

However, if you camp in a hot climate, they could only survive two to three years.

It’s possible for batteries to last up to 7 years for those who go to colder parts of the nation.

Sulfation is what shortens the lifetime of many batteries.

When batteries are kept in storage for an extended period of time, this situation develops.

when the discharge reduces the battery’s capacity to less than 50%

Overcharging is another factor in batteries not lasting as long as they are supposed to.

Although charging is always necessary, overcharging will harm any batteries, including deep cycle batteries.

Dropping the battery or sustaining any other physical harm is a third risk to its longevity.

When handling batteries, caution is advised since you never know which bump, drop, or bang will be the breaking point.

What are the steps for Battery Replacement in an RV Chassis?

There are several wires connecting to the positive and negative lines, which might make this process intimidating for some individuals.

But it’s not as difficult as it seems.

The battery terminals on the chassis battery system are connected via wire looms.

The rest of the wires are connected to the positive or negative looms, respectively.

You simply remove the looms and all of their wires off after removing the bolts that are located right on the terminals.

Then, have a helper hold the loom upright so you can swap out the old batteries for the new ones.

Replacing the nuts completes the process.

The whole procedure should be completed in around 15 minutes.

You should have no issues if all the bolts are snug.

How To Make Your Batteries Last Longer?

Your chassis batteries should follow these guidelines:

1. Maintain the batteries‘ cleanliness by performing routine cleaning of the connections and terminals to prevent corrosion.

Make sure the dirt is also removed.

A connection may be ruined by dirt, which also prevents the battery from operating properly.

2. Keep it charged; most batteries have a minimum charge level beyond which it may be difficult to recharge; don’t let it go low.

So that your battery always operates at peak efficiency, keep the battery charged above the minimal level.

3. Keep an eye on the weather; if you’re putting your RV away for the winter, be sure to keep the batteries in a cool, dry location.

A battery may be destroyed by high temperatures more quickly than corrosion.

The same holds true for freezing conditions.

For your battery to last a long time, you want it to be at a comfortable temperature that is neither too hot nor too cold.

These easy-to-follow tasks may be added to your maintenance to-do list.

It should just take you a little while to clean it up and keep it charged.

A meter should be included in your toolbox.

You can monitor the charge level thanks to it.

The Symptoms Of Bad Batteries In The Chassis

There will be indicators to let you know when it’s time to replace the batteries.

When you start seeing such indicators, check the batteries and start looking for new ones since the deadline can come sooner than you anticipate.

1. There is nothing too complex about the RV not starting.

If all you hear are clicks or silence, your battery has to be changed since it is dead.

There are a few battery manufacturers that enable you to restart the battery, but they are quite uncommon.

2. If your headlights begin to fade or start to dim while you are driving, it is a solid indicator that your battery is losing power.

Those batteries could only need to be recharged, but they might possibly be running out of power.

3. When batteries are losing power, they might hum and crackle, so keep an ear out for odd sounds.

You should change the batteries if you hear these noises or other odd noises.

Recharging may not be possible at this time.

4. The battery is outdated; you should start preparing yourself and your finances to acquire a new battery after three years.

The likelihood that a battery may fail on you increases with age.

Although not all batteries are created equal, a reasonable starting point for battery monitoring is the 3-year standard.


Batteries are quite helpful.

It’s the same as looking after yourself to take care of them.

If you treat them well, you’ll have the strength you need to start the next leg of your trip.

You should be OK for many years if you can only get the correct batteries for your RV.

Until you neglect to clean them.
