A vehicle�s battery system that consists of a second battery, in addition to the first one is known as a dual battery system. The extra battery works as a power source for the auxiliary gas and accessories.

 

A dual battery system is an excellent option if you want to power your gear without exhausting the original battery. Alternatively, you can simply install a second battery. However, this may not do the trick as the other battery will not have a battery management system linked to it.

 

How Does a Dual Battery System Work?

Two batteries operate as two distinct systems in a dual battery system. When a vehicle�s engine starts functioning, the starter battery works with the alternator to provide power to the car and its electronics.

 

When your engine is turned off, the secondary battery provides energy to the accessories and gear inside your car. In other words, you can power your lights, and inverters without keeping your engine turned on worried you will drain the battery.

 

This is made possible due to an isolator that severs the connection between the starter battery and the secondary battery. Hence, it allows you to extract power from a single battery at a time.

 

Having each battery working independently is vital to save your starter battery from exhaustion. The battery isolation also helps the two batteries charge suitably.

 

However, certain 4x4 dual battery isolators may allow the starter and secondary batteries to function simultaneously. This enhances the starting power to the car if there is a dramatic drop in the voltage of the starter battery.

 

The auxiliary battery will probably be a deep cycle battery. Deep cycle batteries are manufactured to be discharged and recharged frequently without facing damage or a shortened lifespan. With a deep cycle battery, you can be at peace knowing that you have a regular power supply and without the risk of damaging your battery.

 

Benefits of a Dual Battery System

Dual battery systems provide a consistent power voltage supply, free from interruptions. Here are the top benefits of adding the system to your vehicle:

• Minimum power loss and potential prevention of total loss
• Better durability
• Saves time as you don�t have to stop operating to pause to recharge your gadget
• Increased mobility
• Reduced fire risk as dual battery systems have fuses installed in the cables of each battery�s positive terminals

 

A dual battery system functions by connecting two batteries to an isolator in order to regulate the power supply. The second battery�s job is typically to power accessories. With a dual battery system, you can get your vehicle started immediately � even if you were camping over the weekend and had the fridge and radio running.
