6 signs that your RV battery needs to be replaced

RV batteries have a difficult job. They have to supply electrical power to the coach 24 hours a day, 7 days a week, 365 days a year. That’s why an RV battery needs to be robust and reliable. It is important to verify the health of your battery and replace it when necessary to protect your RV appliances, electronics, and battery chargers.

So, how do you know when you need to replace your RV battery? Here are six telltale signs:

1. Your check engine light is on

From the battery’s first day in your RV, you’ve been told that a check engine light means there’s a problem with your battery. If the light comes on while you’re driving and stays on while you’re idling, you’d be wise to heed its warning.

It could mean that the voltage coming from your battery is too low, or that it has drained itself and can no longer power your vehicle.

2. You can hear corrosion inside your battery

Corrosion occurs when there’s a leak in the battery. The acid from the leak will eat away at your vehicle’s metal parts, causing damage and making your RV less safe to drive. If you hear any sloshing or bubbling noises coming from your battery, there could be acid leaking inside, and that means it’s time for a brand new model.

3. Your battery recharges slowly

The battery needs to be recharged after use. If it’s not being fully charged or is experiencing a lower charge rate, then there might be an issue with the battery and it needs to be replaced. A good rule of thumb is to replace your RV battery about once every 5 years.

4. Your headlights dim while you’re driving

If your headlights don’t seem to be as bright as they typically are, it could be a sign that your battery is wearing down. One of the most surefire signs of a dying RV battery is that you can feel the dimming (or even hear it) while you’re driving.

5. You notice a bad smell coming from your battery (that isn’t exhausting)

One of the first signs to look out for is a funky odor coming from your battery. If you notice that it smells like rotten eggs, sulfur, or even ammonia, it could be an indication that the cell’s casing is cracked and leaking acid inside your battery.

This is an obvious sign that you need to replace your RV battery right away. In addition to releasing harmful fumes, leaked acid can cause corrosion and damage surrounding components, which will cost you more in the long run.

6. You notice cracks and holes in your battery

If you notice any cracks, holes, or other signs of damage on your battery, it’s time to get a new one. Damaged batteries are more susceptible to leaking and other accidents that might be harmful to you or your RV. Additionally, they’re less reliable and likely to fail while you’re on the road, leaving you stranded in an unsafe situation.
