What is the principle of connecting three 12V batteries to become a 24V battery?
Connecting three 12V batteries in parallel or in series can realize the superposition of voltages and turn three 12V batteries into 24V batteries by taking advantage of the principle of electricity. In some specific cases, this kind of connection makes the higher voltage battery can better meet the demand of the circuit.
How to connect three 12V batteries into one 24V battery?
1. Prepare batteries in good condition and other required tools
First of all, to complete the 12V battery connection work, then you must make sure that the battery itself is not a problem, including the battery can not have broken, leakage, etc., and the battery voltage, capacity, etc. must be consistent with the required specifications, the battery itself is not a problem in order to facilitate the work of the later. Secondly, the battery connection work also needs other necessary tools, including wire stripping pliers, wrenches, multimeters, battery cables and insulating tape, etc., of course, these tools themselves must be in good condition. Prepare these things, you can carry out the 12V battery connection work.
2. Connect the batteries in series and parallel according to the safety regulations.
Before connecting the batteries you need to go through the safety instructions, which will minimize the risk of accidents and protect your life and property. Of course, you must wear the correct labor protection tools, including goggles, insulated gloves, coveralls and so on. The correct wearing of labor protection tools can guarantee the safety of the battery connection operation process.
First of all, we have to understand that the total voltage of the battery in parallel will not change, and the total voltage in series is the sum of the voltage of each part. Therefore, according to the relevant knowledge of electricity, you want to use three 12V batteries connected to become a 24 battery, you need to connect two 12V batteries in parallel, and then and the third battery in series, and then you can get a total voltage of 24V battery. For the wiring, you need to pay attention to the connection of the positive and negative terminals, do not connect them incorrectly.

3. Safety test of the connected battery packs
After you have finished connecting the three 12V batteries, you should not use them immediately. Since you cannot ensure that the connection process is completely problem-free, it is necessary to test the whole system at this time. A multimeter is a common tool used to test the circuitry. Make sure that the whole system has no obvious connection errors and wire exposure, etc., with a multimeter connected to the battery ends, the multimeter shows the voltage of 24V, the circuit system is normal, on the contrary, the circuit system has problems, you need to further be testing.
What are the advantages of connecting three 12V batteries into one 24V battery?
1. To fulfil the operation of equipment that requires a specific voltage.
The most direct effect of connecting these 12V batteries is to increase the voltage, the voltage can be increased to cope with some special circumstances, to meet the needs of a class of equipment operation. Some devices need to be able to work properly under a specific voltage, three 12V batteries can be connected to 24V batteries can be a good supply of these devices to work properly.
2. Provide longer running time
It is obvious that by connecting three 12V batteries in a specific way, not only can the specified voltage be guaranteed to be supplied to meet the operating conditions of the specific equipment, but also, the total amount of power that can be supplied by the battery pack will be increased. Due to the increase in total power, the battery pack can run the equipment for a longer period of time in the same situation, which can provide you with certain convenience.
FAQ
This is not necessarily the case. A 24V battery connected by three 12V batteries has some disadvantages, for example, it is difficult to control the loss of each 12V battery. During the charging and discharging process of the battery pack, the three batteries may have different degrees of loss, resulting in different performance, which in the long run will affect the overall charging and discharging efficiency of the system. However, a 24V battery connected by three 12V batteries can be applied to equipment of specific voltage. To summarize, it cannot be completely said that the performance of 24V battery connected by three 12V batteries is better.
1. You can test your batteries regularly, if you find problems such as circuit aging, damaged batteries and poor contact of battery terminals, you need to make adjustments in time, because these problems may lead to a decrease in the charging and discharging efficiency of your battery packs, or even damage to the circuit system, which will in turn affect the safety of your life and property. In summary, regular testing of your battery pack is necessary for you.
2. Adhering to the charging regulations may be a good way to make your battery last longer. If you use an unsuitable charger or charge irregularly, it will lead to abnormal charging and discharging process of your battery, destroying the normal chemical reaction inside the battery, which will lead to the overall performance of the battery pack and reduce its service life, or even cause safety accidents. Therefore, you should comply with the standardized operation mode, so that you can have a longer service life of the battery.
