Product Description
Battery Doctor 20090
About This Item
The WirthCo 20090 Battery Doctor 75 Amp100 Amp Battery Isolator is the perfect solution for anyone in need of a reliable and efficient battery isolator. Designed with water resistance in mind, this battery isolator is suitable for marine use (IP62), making it ideal for boats and other watercraft. One of the standout features of this battery isolator is its priority charging for the starting battery. This ensures that your vehicle's primary battery receives the necessary power to start the engine, even if the auxiliary battery is being used or charged.
This guarantees peace of mind and eliminates any worries about being stranded due to a dead battery. In addition, this battery isolator is equipped with overcurrent and surge protection, which is especially important for vehicles with electronic systems. This safeguard prevents any potential damage to your vehicle's electrical components during the charging process. The WirthCo 20090 Battery Doctor 75 Amp100 Amp Battery Isolator also includes a manual override for the starting battery. This feature allows you to manually override the isolator and draw power directly from the starting battery if needed.
This can be useful in emergency situations or when your auxiliary battery is depleted. Automatic charging of the auxiliary battery is another key feature of this battery isolator. Once the starting battery is fully charged, the isolator will automatically divert power to charge the auxiliary battery. This ensures that both batteries are always in optimal condition, ready to power your accessories or equipment. This Battery Doctor 20090 Battery Isolator has a maximum capacity of 100 amps, making it suitable for a wide range of applications.
Whether you need to isolate batteries in an RV, boat, or other vehicles, this battery isolator can handle the job with ease. Please note that this product is subject to California Proposition 65, which requires us to provide the following warning: WARNING: This product can expose you to chemicals, such as Diisononyl phthalate or others listed on the product, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, please visit www.P65Warnings.ca.gov. When it comes to battery isolation, trust the Battery Doctor brand. With a reputation for quality and reliability, you can be confident in your purchase.
Don't settle for anything less than the best - choose the WirthCo 20090 Battery Doctor 75 Amp100 Amp Battery Isolator for all your battery isolation needs.
