Your Car Is Better Off With a Dual Battery Charging System with Energy Supply For All Accessories

The primary function of your car’s battery is to power the starter, the mechanism that sparks the plugs and cranks a cold engine. When your car is running, the alternator recharges the battery and also provides electricity to accessories. This arrangement is good for any car with no increased demand for power.

However, the electrical and power demands of modern cars, especially 4WDs, SUVs, recreational vehicles, caravans and motorhomes are hardly typical anymore. These vehicles are fitted with many accessories such as a fridge, radio, reversing camera and laptop. To keep these accessories running when your vehicle is parked, it needs to have plenty of reserve power. This electrical capacity can be provided by a dual battery charging system that can power your extras without running your battery flat.

More amount of electricity available to you

A dual battery system with the batteries connected in parallel creates double the amount of electricity available to you. Such an arrangement can keep your vehicle’s lights, fridge and onboard entertainment systems running even if your car is not running. However, your batteries can eventually go flat if there is a constant energy drain. That is why many modern vehicles come fitted with dual battery charging systems that temporarily take one of the batteries offline to ensure that both batteries do not go flat together. You can manually run your car on either battery by manually flipping a switch. Some switching systems allow only for the secondary battery to be used for bigger power draws. Smart switches automatically make your secondary battery in or out of the main electrical system based on different factors. In most dual battery installations, the second or auxiliary battery is used to power the accessories.

Advantages of dual car battery charging systems

• You can start your car right away even if the fridge and radio are running and you have been camping out for days.
• You won’t have to keep the engine running to charge the battery. Unnecessary pressure on the engine can deteriorate its condition sooner.
• Two batteries in a dual battery charging system work together to reduce the load on the engine.
• You can expect your car to keep running on rough terrains or a rough river even if the engine might have stalled.
• The two batteries can be connected in parallel to provide extra power to the starter battery. This helps the winch and motor work better under load.

It can be an outright disaster if your car fails to start at night on a desolate location or in the woods with no help around. With a repaired and fully functional dual battery charging system, you will have peace of mind as you need not worry of getting stranded in the middle of nowhere, waiting for help to arrive.

Types of dual battery charging systems

A regular lead-acid battery is designed to be mounted under the bonnet. It’s great as a backup starting battery but is not suitable to run accessories for a long period of time. Each time a lead-acid battery runs flat, its lifespan is reduced, so you may need to replace it often.

On the other hand, a deep-cycle battery is a great option to run the accessories in your car. It’s designed to be repeatedly drained and recharged. These types of batteries may not be suitable to mount under the bonnet.

A dual-purpose battery can be a good compromise between the two. These are semi-cycling and are sturdily designed for off-road uses. These batteries are ideal for dual power applications and can be used for starting the car and also supplying energy to meet its overall energy demands of the engine, gears, lighting and accessories.

Battery management system

However, it is equally important to attach a battery management system with your car’s dual battery system as you may still get stuck in the morning with two drained batteries. Your secondary battery may not be charging, it may have been drained of the energy, there could be charging, connectivity, wiring or other issues, there could be fluctuations in voltage or the battery may need replacement. If your battery has issues, you will experience a starting problem or there could be inefficient operations of your fridge or other accessories you use in your car.
