Overview / What Is Blue Sea Add-A-Battery?
The Blue Sea Add-A-Battery is a compact, high-quality battery switch designed to safely add an extra battery bank to your boat’s electrical system without complex rewiring. This product offers an automatic switch-over feature that prevents the main battery from being drained when using auxiliary loads and helps isolate batteries to maintain optimal charge levels.
Key features include its marine-grade materials, corrosion resistance, and simple installation. This device is crucial for boat owners who want to expand their battery capacity safely and efficiently while protecting their electrical systems.
How Blue Sea Add-A-Battery Works
This innovative switch allows you to connect a secondary battery that can be isolated or combined with the main battery system. It protects your starter battery from deep discharge while powering additional equipment like trolling motors, electronics, or cabin lights from the auxiliary battery.
By automatically isolating the batteries when the engine is off, it ensures the starter battery remains charged and ready to start your engine every time. When the engine runs, the batteries can be linked to recharge both simultaneously.
Why Use Blue Sea Add-A-Battery for Marine Engines?
Marine engines demand reliable starting power, and any power shortage can cause frustrating delays. The Blue Sea Add-A-Battery provides a simple yet effective solution to extend your boat’s electrical capacity without complicated wiring changes or risking your starter battery’s health.
It also offers peace of mind during extended trips by providing auxiliary power to onboard systems, preventing battery failures that could compromise your safety or comfort on the water.
Compatible Applications
- Fishing boats with trolling motors
- Powerboats with multiple battery banks
- Commercial vessels requiring additional battery capacity
- Yachts and cruisers with complex electrical systems
Maintenance Tips
Maintaining your Blue Sea Add-A-Battery switch ensures optimal performance and extends its lifespan. Marine environments are harsh, so proper care is essential.
First, regularly inspect the switch and terminals for corrosion or buildup. Clean contacts using a marine-grade electrical cleaner and apply dielectric grease to protect against moisture and salt exposure. Check wiring connections to confirm tightness and prevent voltage drops.
Also, test the switch’s functionality seasonally, especially before extended trips. Make sure the isolation and combination modes operate smoothly to avoid unexpected power losses.
Expert Advice and Pro Recommendations
Boat electrical expert recommendations for using the Blue Sea Add-A-Battery emphasize professional installation, especially if integrating into complex systems. While it is user-friendly, ensuring proper wire gauge, secure mounting, and adequate fusing improves safety and reliability.
Additionally, pairing this device with quality marine batteries and a smart charger can greatly enhance battery life and power efficiency on board. Use marine-grade cables and connectors for best results.

Installation Guide: How to Install Blue Sea Add-A-Battery
Installing the Blue Sea Add-A-Battery is straightforward but requires attention to detail. Begin by disconnecting all power sources to prevent shorts. Mount the switch in an accessible, dry location near your batteries.
Connect the starter battery cable to the “Battery 1” terminal and the auxiliary battery cable to “Battery 2.” Connect the load terminal to your distribution panel or loads. Always use the recommended cable size and marine-grade terminals to ensure safety and minimize voltage drops.
Troubleshooting Blue Sea Add-A-Battery Issues
Common issues with the Blue Sea Add-A-Battery include battery drain, failure to isolate batteries, or difficulty switching. To troubleshoot, first check for loose or corroded connections. Verify that the switch is operating correctly by manually switching positions.
If battery drain occurs, test both batteries individually for faults or parasitic loads. Use a multimeter to check voltage continuity across terminals. Sometimes, replacing the switch is necessary if internal contacts wear out after extended use.
Detailed FAQ Section
What is the primary function of the Blue Sea Add-A-Battery in marine electrical systems?
The primary function of the Blue Sea Add-A-Battery is to safely add a secondary battery bank to your boat’s existing electrical system, allowing you to power additional devices without draining the starter battery. It isolates the batteries when the engine is off and connects them when the engine is running, ensuring both batteries receive a charge without risking starter battery depletion. This function is crucial for reliable engine starts and extended power availability onboard.
How do I install the Blue Sea Add-A-Battery correctly on my boat?
Installing the Blue Sea Add-A-Battery requires careful planning and adherence to safety standards. Start by disconnecting all batteries and power sources. Choose a dry, accessible mounting location close to your batteries. Connect the primary battery to the “Battery 1” terminal and the auxiliary battery to “Battery 2.” Connect your load or distribution panel to the common output terminal. Use marine-grade cables and fuse protection as specified in the manual. After wiring, check all connections for tightness and test the switch function before powering up your system.
What maintenance is recommended for Blue Sea Add-A-Battery to ensure long life?
Maintenance for the Blue Sea Add-A-Battery mainly involves regular inspection of terminals and wiring for corrosion or wear. Clean the terminals using an approved marine electrical cleaner and apply dielectric grease to protect against moisture and salt damage. Ensure cables are secure and free from fraying. Periodically test the switch’s isolation and combination modes for smooth operation. If you notice any irregularities, such as intermittent switching or power loss, inspect wiring and replace any damaged components promptly.
Can I use Blue Sea Add-A-Battery with any marine battery type?
Yes, the Blue Sea Add-A-Battery is compatible with most marine battery types, including AGM, gel, and flooded lead-acid batteries. However, it’s important to match battery voltages (usually 12V or 24V systems) and ensure the auxiliary battery is suitable for your electrical load. Using batteries with similar capacity and chemistry will optimize performance and charging efficiency. Always consult your battery manufacturer and the Blue Sea product specifications to ensure compatibility with your setup.
What are common troubleshooting steps if the Blue Sea Add-A-Battery fails to isolate batteries?
If the Blue Sea Add-A-Battery does not properly isolate batteries, start by checking for loose or corroded connections at all terminals. Test the switch manually to confirm it changes positions smoothly. Measure voltage on each battery and across the switch terminals to identify any unintended continuity.
