A dual battery charging system contains two batteries connected in parallel that doubles the amount of electricity available to you. In the least complicated setup, its installation includes a conventional on-off switch that needs to be operated manually. At the campsite, you will throw the switch the other way so that your accessories such as fridge and lights are not using the main battery which is used by your vehicle to start the engine. A four-way manual switching provides you more control over your dual battery charging system. You can manage which battery is doing what job. Some switches are designed so that only the secondary battery can be used for bigger power draws such as fridges. However, the problem with manual switching is that you have to remember to put the correct battery on at the right time, failing which you may end up without sufficient power to start your car the next day. You may not have enough electricity to crank your engine on a cold day after an overnight stay on a campsite. The dual battery charging system in modern automobiles are set up in a way that it can temporarily take one battery off from the main electrical system so that both batteries do not go flat at the same time. The system automatically takes your second battery out of your main battery based on a variety of factors. Automatic dual battery charging system In the simplest of the automatic dual battery charging system, the setup can switch on the secondary or auxiliary battery for charging as soon as the engine is cranked. The solenoid then automatically isolates it from the system when the engine is turned off. This ensures that both of your batteries are not drained at the same time as accessories draw their power from the secondary battery, not the main battery. However, the problem with this setup is that the battery may end up drawing power from the secondary battery instead of the alternator when it connects to the circuit as you turn on the ignition key. Moreover, as the secondary battery is usually of a different type than the starter or main battery, it may get drained before the main battery is able to crank your engine. If this happens, you end up having two dead batteries at the same time! Voltage-sensitive relays To prevent this scenario, some modern Australian cars feature voltage-sensitive relays that do not connect the secondary battery to the system when you start your car. It waits until the engine is running and first fully charges the main battery of your vehicle. Once you’re at the campsite, both batteries will be able to provide you power until the voltage in the main battery falls below a certain level. At this point, the voltage-sensitive relay will act in the other direction to isolate the batteries again. This arrangement ensures that both of your batteries do not discharge completely at the same time, and you always have the power to crank your engine or run your onboard accessories. Fixing problems with your automotive dual battery charging system However, if you are experiencing problems with your dual battery charging system, such as engine cranking slowly, battery uses too much water or overheats, the auxiliary battery does not charge, lights are dimmed, there is noise under the hood, or your car doesn’t start at all, it signals a problem with your automotive dual battery charging system.

Your auto mechanic Brisbane will attend whichever address suits you best, at a time and date which is the most convenient for you. The electrical demands of your 4 x 4, camper, caravan,. SUVs and trail-friendly trucks in Australia are hardly typical as they have a higher demand of electrical power. Even if you use your battery with the engine on, it will require more than a few minutes of winching to charge it. This will increase the energy debt on your vehicle as it will not be able to recharge the battery with the demand of its use, especially if you are using your automobile’s electric power in your vehicle at a campsite. In a typical single battery system, the starting battery and accessories are powered by a single battery, increasing its chances of drainage with an onboard entertainment system or other accessories requiring a large load in use. Your afternoon fishing trip could suddenly turn suddenly serious if your main battery is too drained to start the engine. Meeting the increasing demand for energy The solution for the increasing demand of your vehicle is a dual car battery charging system. At its most basic level, a dual battery charging system has two batteries connected in parallel that double up the amount of available electricity to you. However, one battery after another will eventually go flat with this arrangement. A dual battery charging system will provide you the electricity to power your additional comforts such as fridge or camping accessories without flattening your main battery. A dual battery charging system allows you to power your various electrical components such as camping lights and fridge without draining the main battery. It is designed in a way that both the main battery and the auxiliary battery benefit from the automated charging system or the alternator. However, the two batteries need to be separated so that the secondary battery does not drain the main battery when it is being used. For this, a smart solenoid or a smart battery isolator may be used in the dual battery charging system. Alternator to boost electrical output The alternator used in your dual car battery charging system consists of a stator and coil windings inside which a rotator revolves. The rotor is an electromagnet whose rotation inside the stator coils generates much more electricity inside the coils. Electromagnets in the alternator helps in boosting the output of the electric current. The alternator has a transistor-operated control device that is used to regulate the voltage to the electromagnet as required. A smart isolator keeps the secondary battery disconnected until the starter battery is fully charged. This way, the smart isolator ensures that you always have enough power to start your vehicle on a campsite after a long time of idling. Some modern smart isolators allow you to jumpstart the starter battery off the secondary battery. Intelligent maintenance charger Some models of smart isolators feature DC to DC chargers to meet the strict fuel and emission targets. The charger makes for two completely separateseparate electrical systems. Some high-end automobile models can even regulate solar inputs. If your vehicle doesn’t have a car dual battery charging system, you may be suggested to install one by the auto mechanics Brisbane. A dual battery charging system may become dysfunctional due to a variety of reasons, such as loose connections, corroded terminalsterminals, and reduced capacity to hold a charge. Addressing the problem with your dual battery charging system A battery condition indicator is provided on your 4 x 4 to show your battery’s state of charge. A warning light on your dashboard will show that the battery is not being properly charged. If you have problems with your dual car battery charging system, you need to get have it inspected by RACQ-approved auto mechanics Brisbane who can diagnose the problems with your car’s charging system. North Brisbane based Sandgate Auto Electrics has RACQ-approved mechanics who can diagnose all the electrical and mechanical issues with your car including its dual battery charging system.

To keep your fridge running while your car is parked, you need a plentiful supply of electric power. For many people, adequate supply of electric power in the vehicle is not a luxury but a requirement for work so they can keep their gadgets and equipment running. Equipment such as safety lights, radio, and laptop charger. When the vehicle is stationary, a dual car battery system is must for such vehicles.
The second battery in a car dual battery system is usually isolated from the primary or main battery, and installed in the engine bay, load area or passenger compartment so that it does not drain the power out from the main battery. Some 4 x 4s from Australian manufacturers including Piranha, ARB, TJM, and also Toyota from Japan come fitted with a dual battery system and have space created in the engine bay for its installation from the factory itself. Most diesel Toyota Prado’s come fitted with a dual car battery system while some petrol versions of the model have a strong factory-engineered foundation for a second battery. Fitting a secondary battery In many other vehicles, you may have to figure out where to place the secondary battery. If you need to install a secondary battery in your single battery car, you may require extra hardware such as a strong fabricated steel tray to carry the 15 kg or more load of the secondary battery. Fasteners should be adequately sized, and large washers used to evenly spread the load across the panel work. You may also need to pay extra attention to the type of battery to be chosen and the wiring needed. Batteries hate the heat, so they should be installed away from the hot areas of your vehicle. The secondary battery of a car dual battery system is used to power the accessories such as fridges and entertainment systems. That’s the reason a deep cycle or dual-purpose battery is often installed. Wiring of the primary or starter battery remains largely unaffected in a dual battery system to help it start the car with ease. Charging your car’s batteries The only thing worse than a warm beer is your car refusing to start. This can mean a problem with your car’s battery. If that is the case with your car, you need to get it diagnosed by an auto mechanic Brisbane. Many batteries under warranty are just deeply discharged and work fine again when properly recharged. A secondary battery can be wired in a way that allows it to be charged when you are driving and disconnected when you set up camp and operate the fridge and other accessories. When you start your vehicle, the switch will connect the secondary battery to your car’s electrical system. This allows for its charging from the alternator. However, you need to remember to flick the switch to isolate or charge the accessory battery, failing which the entertainment system and interior lights may continue to operate from the main battery. If that happens, the main battery may run flat and you may not be able to start your car at all. Car battery diagnosis and replacement The auto mechanic Brisbane will diagnose any problems with your car and may either suggest a repair or a car battery replacement. In many cases, there may not be any issue with your car’s batteries, but the vehicle is not used enough for the batteries to be charged properly. In that case, the auto mechanic Brisbane may suggest a battery repair, instead of a full replacement. A car should be driven for longer distances and frequently. This way, the battery gets enough time to be charged. If you drive your car for short durations and do not drive it often, the battery may not get time to be fully charged. Your car’s battery may have short-circuited cells, corroded or damaged plates due to vibrations, low electrolyte (fluid) level, or broken internal connections. The auto mechanic Brisbane will have all the batteries of the leading manufactures that can be replaced and fitted in your car. They use the newest diagnostic tools and techniques to provide car battery repair and replacement services in and around Brisbane. A car battery stores energy in the form of chemical energy which is then converted into electrical energy for use by the electrical systems of your car. The car battery provides energy to your car’s starter motor and also powers all the other accessories such as power steering, power window, lights, electrical systems, onboard entertainment systems and fridge. Besides providing electrical energy, the car battery also stabilizes the voltage and keeps the electrical current steady to keep the engine running. Without a properly functioning battery, your car will not start. In addition to the starter motor, spark plugs, lights and electronic appliances all require electrical energy. Car battery replacement at regular intervals ensures that you get the best performance from your car, and will not face problems on the road. Construction of battery A battery consists of positive and negative electrodes. In a lead-acid battery, there is a positively charged plate consisting of lead oxide which is immersed in an electrolyte. It also has a positive grid consisting of a lead alloy. This is used to hold the active material and serves as a current collector. A grid has two plates, one made of lead and the other one of lead oxide. In most batteries, there are six cells, each providing 2 volts energy; therefore, it becomes a 12-volt battery. Negative and positive electrodes in the battery are separated by a separator made of polyethylene material to facilitate an efficient flow of electric current. A positive plate set is made by combining several positive electrodes, while a negative plate set is made by combining several negative electrodes. Negative and positive plate sets make a battery cell. The electrolyte of the battery consists of a mixture of sulfuric acid and distilled water. The electrolyte can be in a liquid or gel form. In new cars with Start-Stop applications, the electrolyte is bound to a glass mat. This arrangement provides greater cycle stability and eliminates the problem of acid layering as the acid is bound to the glass mat, It also helps provide reliable performance in vehicles with increased demand for energy. The new generation of car batteries in micro-hybrid vehicles have lithium-ion cells that operate at 48V. Battery terminals Battery terminals consisting of positive and negative straps provide an interface between the battery and electrical system of your vehicle. Straps are welded to the top of each element to provide an electrical connection to the terminals. A battery also has battery paste made of lead-oxide mixture that creates lead oxide and sponge lead. The paste adheres to positive and negative grids of the battery. The battery case holds the battery plates, electrolyte and cast-on-straps. It is usually made up of a polypropylene resin and has a robust construction to minimize any vibration impact and extend the battery life. What is battery stratification and how it is harmful If a battery is operated at too low a voltage, stratification occurs as the acid in the electrolyte stratifies. This means sulfuric acid settles on the bottom while water moves to the top due to a difference in densities. Because of this, only the middle section of the electrolyte is available for charging purposes. The process of stratification is accelerated when you only take short drives and use all your electrical appliances as the alternator doesn’t get enough time to recharge the battery. A vast majority of batteries are SLI or starting lighting ignition type. The vehicles with a high demand of electrical energy, such as 4x4s, caravans, campers and recreational vehicles feature two batteries, one main battery that powers the starter motor to crank the engine, and one auxiliary battery that provides power to the other electrical components such as fridge, power windows and lights. Such cars also have a dual battery charging system that charges the batteries so that you have enough power to start your engine and also keep your accessories running. Issues with your car battery If the battery isn’t consistently charged to an adequate level, the lead sulphate in it crystallizes on the electrodes and forms a larger crystal structure. This process is known as sulfation that reduces the battery’s capacity to cold start your car. Sharp crystals may also cause short circuit in the cells. To prevent sulfation, the battery should not be subjected to low charging for an extended period of time. Your car battery can last well beyond three years, but you should have its current condition inspected by a car battery replacement service especially if you are facing battery problems such as slow cranking of engine, dim lights, rotten egg smell (sulfuric odour) around the battery, bloating battery case or low battery fluid level. Also, if you have a dual battery charging system, it may develop problems and you may not get enough power to navigate a steep road.

Also, you risk your life and that of other drivers on the road with malfunctioning power steering, engine or lights. Get your vehicle inspected for a possible car battery replacement or repair for the safety of everyone. Your Car Is Better Off With a Dual Battery Charging System with Energy Supply For All Accessories5/27/2020 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
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.
