Welcome to another edition of Tech Tip Tuesday! This week, we’re diving into your most pressing RV questions and offering expert advice to keep your RV systems running smoothly.
Upgrading Your Water Heater Fittings
Many RVs come with plastic water heater fittings, which can become brittle and crack over time. Replacing these plastic fittings with brass fittings can greatly improve durability and reduce the risk of leaks or damage. Brass fittings are more resistant to temperature changes and wear, making them a long-term solution for your RV's water system.
Treating Grey Water Tanks
Proper maintenance of your grey water tank is essential for preventing odors and buildup. Use a tank treatment specifically designed for grey water systems to break down grease, soap scum, and other residues. Regular treatments not only keep your tank clean but also prevent unpleasant odors from permeating your RV.
What Percentage Does My RV Battery Need to Be at to Start My Generator?
For many RV owners, understanding the relationship between your RV battery and generator is crucial for smooth and uninterrupted travels. One common question is: What percentage does my RV battery need to be at to start my generator? Let’s break it down.
The Role of Your RV Battery in Starting the Generator
Your RV generator relies on the house batteries to crank the starter motor. If your battery level drops too low, it won’t have enough power to engage the generator’s starter. Typically, your RV battery should be at least 50% charged to reliably start your generator.
Why 50%? At this level, there’s enough voltage and current available to turn the starter motor over without risking damage to your battery or the generator’s starter.
Voltage vs. State of Charge
-
12.6V - 12.7V: Fully charged
-
12.4V: About 75%
-
12.2V: Around 50%
-
12.0V: About 25%
-
Below 12V: Critically low
If your RV battery is showing less than 12.2 volts, you’re likely to encounter difficulty starting your generator. Additionally, consistently draining your battery below 50% can shorten its lifespan significantly.
Tips for Ensuring Reliable Generator Starts
-
Regular Battery Maintenance: Check water levels (if applicable) and ensure terminals are clean and corrosion-free.
-
Monitor Battery Levels: Use a battery monitor to keep an eye on voltage and state of charge.
-
Charge Batteries Properly: When plugged into shore power, ensure your batteries are charging correctly.
-
Limit Excessive Drain: Avoid leaving high-drain devices running when battery levels are low.
Understanding Battery Bank Size and Age
Older batteries may struggle to hold a charge, even if they display an acceptable voltage. If you find yourself frequently struggling to start your generator, it might be time to replace your batteries or consider upgrading to a larger battery bank.
