5 UTV Accessories that May Cause Battery Problems

While UTV (Utility Terrain Vehicle) accessories can enhance your off-road experience, it’s essential to consider their impact on your vehicle’s battery.

Here are five UTV accessories that can potentially cause battery trouble:

1. Powerful Sound Systems: UTV sound systems, including amplifiers, speakers, and subwoofers, can draw significant power from the battery. If these accessories are used excessively or at high volumes, they can put a strain on the battery, potentially leading to a drained battery or reduced overall battery life.

2. Auxiliary Lighting: Additional lighting options like LED light bars or spotlights are popular UTV accessories. These lights can consume a substantial amount of power, especially when used for extended periods. It’s important to monitor their usage and ensure you have an appropriately sized battery or consider adding a secondary battery or a battery isolator to prevent draining the main battery.

3. Electric Winches: Electric winches are commonly used for off-road recovery or pulling tasks. However, they draw a significant amount of power when operating. If the winch is used frequently or for extended periods without the engine running, it can quickly drain the battery. It’s advisable to keep the engine running while using the winch or consider upgrading to a higher-capacity battery.

4. Heated Accessories: UTV accessories such as heated seats or heated grips are popular for cold weather riding. While they provide comfort, they require electrical power to operate. Constant usage of these heated accessories without the engine running can drain the battery, particularly if the battery is not adequately sized or if the vehicle’s charging system is not optimized for the additional load.

5. High-Powered Electronics: Additional electronics such as GPS units, communication systems, or onboard diagnostic devices can draw power from the UTV’s battery. If multiple high-powered electronics are connected and used simultaneously, they can place a strain on the battery, potentially leading to a drained battery or diminished performance.

To minimize battery-related issues, it’s advisable to:

Opt for a higher-capacity battery or limit the use of power-intensive accessories when the engine is not running. Regularly monitor and maintain the battery’s health and charge levels. However, since all vehicle owners love accessories, consider adding a dual battery with an isolator setup. A dual battery setup with a battery isolator kit is beneficial for several reasons, particularly in vehicles like UTVs or off-road vehicles that require additional power for accessories or extended periods of operation.

Here are some benefits why you might need a dual battery setup with an isolator:

    • Power for Accessories: Many off-road enthusiasts add various accessories to their vehicles, such as winches, auxiliary lighting, sound systems, and communication devices. These accessories can draw a significant amount of power and may drain the vehicle’s primary battery if used for extended periods. A dual battery setup allows you to power these accessories without risking a drained primary battery, ensuring that you always have enough power to start the vehicle.
What to Consider When Choosing a UTV Light?
    • Extended Power Supply: In certain situations, you may need to operate power-consuming accessories, such as a winch or auxiliary lighting, for an extended period without the engine running. A dual battery setup provides a secondary battery dedicated to powering these accessories, while the primary battery remains isolated and reserved for starting the engine. This ensures that you have power available for these accessories without compromising the ability to start the vehicle later.
    • Increased Battery Life: A dual battery setup with an isolator helps extend the overall life of your batteries. The UTV battery isolator kit prevents the secondary battery from draining the primary battery, and vice versa, by ensuring that power flows in one direction only. This prevents deep discharging of both batteries and allows each battery to maintain its optimal charge level, resulting in prolonged battery life.

  • Enhanced Electrical System Reliability : By isolating the batteries from each other, a dual battery setup reduces the risk of electrical system failures. If one battery develops a problem or is discharged, it will not affect the other battery. This redundancy provides increased reliability for your electrical system, especially in remote or off-road situations where a failed battery can leave you stranded.
  • Flexible Power Management: With a dual battery setup, you have more control over how power is distributed and managed. You can choose when to activate or deactivate the secondary battery based on your power needs. This flexibility allows you to optimize power usage and preserve battery life, especially during long trips or off-grid adventures.


Consulting with a UTV expert or contacting the manufacturer for specific guidance on your UTV model and the accessories you plan to use can also provide valuable insights on battery management and optimization. You can also ask the TrueAm support team for best advice on installing a second battery with isolator technology.
