Checkout the Proper Way to Install Car Dual Battery System
Before you start working with the marine electrics services, learn the proper procedure. Keep the tools and switches within your reach.
Just like car dual battery system, it is equally essential to establish a second battery in your boat. Adding a second battery to your boat is a wise option as it will offer you more battery capacity. Moreover, you can use the second battery, in case you have drained out the first one. Just quickly start your engine with the second one and gradually shift to the first one as soon as it gets completely charged.
An easy job
Adding a second battery is an easy task. All you need is to install a dual-battery connector switch. Once done correctly, a single switch will allow you to power one of the two batteries. You can either combine or disconnect them.So let’s get started.
Tools and equipment
Installation and use of dual marine batteries is a part of Marine Electrics Services. To install a switch, you can either call a professional or do it yourself, provided you are a pro. Before you start, go through the list below and keep all the necessary tools ready.
- A second battery that meets engine specifications
- A battery selector switch from a reputed company
- Battery box coming with battery bracket
- Black or red cable with 2/0 marine-grade specification
- Soldered or crimped cable lugs with 2/0 marine-grade specification
- Het contract tubing to fasten the cable-lug connection
- You can also keep pre-made cables if you want
- Terminal lids for each of the positive terminals
- Drill bits and power drill
- Mounting screws made of stainless steel
- A set of screwdriver
- Socket haul set
- Heavy-duty soldering gun
- Tie wraps and cable clamps

Five easy steps
Installation of dual marine batteries can be a little different from car dual battery system.
- Switch selection:Make sure the switch you buy is suitable to work for two batteries. It will be enough if it comes with 250 amps rating. Some switches come with security locks to prevent boat theft.
- Engine check:Look for your engine specification before moving towards the battery installation. The process should be in sync with the ABYC Standards and comply with the Coast Guard. Use the battery box to keep the wet-cell batteries intact. Keep the positive terminals covered with nonconductive caps.
- Choose location:Selector switches generally have 4-6 inches trail. So you need to pick a location for your switch where there is enough space. As per the ABYC standard, you should place the switch closer to the battery so that it is easily accessible.
- Marine cable:When you buy the cables, check for the ‘marine cable’ stamp on it. Connect both the positive terminals to that of the corresponding posts at the backside of the switch. You can then attach the positive cable to the output port of the switch.
- Cable installation: To make the dual battery system work properly, you need to install crossover cables in between the two negative terminals of the batteries. Attach the negative cable haul from the engine and connect the supporting negative wires to one of the negative battery outlets.
