Customer Questions & Answers
-
Question:
What is the purpose of the RECOIL 500 Amp Mobile Audio Battery Isolator?
Answer: The RECOIL 500 Amp Mobile Audio Battery Isolator is designed to manage the power supply of your audio system while ensuring that your vehicle's battery remains charged. It prevents power drainage by disconnecting the audio system from the main battery when the engine is off, protecting the vehicle's starting battery from being depleted. This is particularly useful for car enthusiasts who have high-demand audio setups and need reliable power management to maintain performance without risking battery drain. -
Question:
How does the high current starter relay in the RECOIL 500 Amp product work?
Answer: The high current starter relay operates by ensuring a strong connection between the vehicle's battery and the starter motor during engine start-up. When the ignition key is turned, the relay closes the circuit, allowing high current to flow and ensuring the engine starts efficiently. This is critical in vehicles with powerful audio setups, as they typically draw substantial power; the relay helps manage that load effectively without causing voltage drops that could affect system performance. -
Question:
Can I install the RECOIL battery isolator myself?
Answer: Yes, the RECOIL battery isolator can be installed as a DIY project if you have basic automotive wiring knowledge. It typically requires connecting the isolator to the vehicle's battery and the audio system, making it relatively straightforward. Detailed instructions are generally included, allowing you to follow along with the installation process. However, if you're uncertain, consulting a professional technician can help ensure a secure and correct installation for optimal performance. -
Question:
Is the RECOIL Mobile Audio Battery Isolator compatible with all vehicles?
Answer: The RECOIL Mobile Audio Battery Isolator is designed for a wide range of vehicles, but compatibility can depend on factors such as the vehicle's electrical system and battery configuration. It is specifically designed to handle high current applications, making it suitable for most cars, trucks, and SUVs. It's advisable to check the specifications against your vehicle's electrical system to confirm compatibility and ensure seamless operation with your audio equipment. -
Question:
Does the battery isolator require any maintenance?
Answer: Generally, the RECOIL battery isolator requires minimal maintenance due to its durable construction. Periodic checks on the connections and wiring are recommended to ensure everything remains secure and free from corrosion. This helps in sustaining optimal performance. In practical terms, after installation, users mainly engage with the isolator through their regular audio system checks, ensuring that everything operates smoothly without draining the vehicle's battery. -
Question:
What are the benefits of using a battery isolator?
Answer: Using a battery isolator, like the RECOIL model, offers several benefits; primarily, it extends the lifespan of your vehicle's starting battery by preventing over-discharge while allowing for the use of a high-performance audio system. It provides peace of mind for vehicle owners who want to enjoy their audio experience without worrying about power drain. Additionally, it helps in managing multiple battery systems, making it ideal for vehicles equipped with auxiliary batteries or those used for extensive power-hungry applications. -
Question:
What features make the RECOIL isolator stand out from others?
Answer: The RECOIL 500 Amp Mobile Audio Battery Isolator stands out due to its high current handling capability, designed for robust audio systems. It features a compact and durable build, ensuring reliable performance even in demanding conditions. The isolator is also user-friendly, providing straightforward installation options, and it effectively manages power flow without sacrificing audio quality. These characteristics make it a preferred choice among car audio enthusiasts looking to optimize their sound systems while protecting their vehicle's battery. -
Question:
Can the isolator be used with a dual battery setup?
Answer: Yes, the RECOIL battery isolator is highly effective for dual battery setups, allowing users to integrate an auxiliary battery for their audio systems while keeping the main starter battery secured. This setup is ideal for those who use their vehicles for camping, tailgating, or sound competitions. The isolator ensures that power is directed appropriately, preventing the starter battery from draining while enabling high power usage for the secondary battery, providing flexibility and performance without compromise. -
Question:
How do I know if I need a battery isolator?
Answer: If your vehicle is equipped with a high-powered audio system or auxiliary battery, or if you've experienced power drainage issues during use, a battery isolator like the RECOIL model is likely needed. Signs include dimming lights or audio cutouts when the car is off. Utilizing an isolator helps protect your starting battery while allowing for uninterrupted audio experiences, perfect for those who frequently use their vehicles for extended audio playback without the engine running. -

RECOIL Battery Chargers Editorial Review
The RECOIL 500 Amp Mobile Audio Battery Isolator and High Current Starter Relay is an affordable option for car audio enthusiasts who need to manage multiple car batteries of different chemistries. The product claims to have a coil amperage of 500 and comes with everything needed to install, except for wiring. However, there are mixed reviews of the product's durability and effectiveness. One user reported that the product initially worked great but stopped disengaging when they stopped using the secondary battery, requiring them to tap it with a screwdriver to get it to disengage. Another user mentioned a very audible whining noise that comes from the unit itself when the secondary battery is active. Several users also reported issues with the product's durability, stating that the nuts are fragile and easily broke. Despite these issues, there are still positive reviews of the product. One user reported using it to isolate a winch on their Jeep, stating that it was a must-have feature to prevent a runaway if the contactor on the winch welded itself together. Another user who had previous success with other RECOIL products felt confident in their purchase of the Battery Isolator and recommended it for car audio systems.
