What is the difference between a 12V40A battery and a 12V60A battery for a car

12V40A battery and 12V60A battery, their working voltage is the same, both output 12V, the difference is that their load capacity is different, that is, the output current is different. A 12V60A battery can output a rated current.

Larger, with greater load capacity.

Normally, the amount of electrical energy that can be stored in a battery is relatively rated, and as the plates peel off and the surface activity decreases, the battery's electrical and chemical energy.

As a result, the conversion efficiency decreases, resulting in a gradual decrease in the battery's ability to store electrical energy. AH is the unit of capacity of the battery, which indicates the volume of the battery. A battery with a nominal voltage of 12V60A can theoretically discharge continuously at a current of 60A below the output voltage of 12V, until its charge is insufficient and the voltage is reduced to a shutdown voltage.

Since the electrical energy and voltage are rated, the output power of the battery.

It increases as the current increases.

The power of the battery varies depending on the load added, but this load is not unlimited, and an electrical appliance that applies too much power, quite a short circuit with the battery, will damage the battery.

It should be the difference between 12v40ah and 12v60ah!!

Ampere-hours stands for battery capacity! 12v60ah is bigger than 12v40ah! It's also more expensive than him!

Hello, the battery capacity is not the same, 60A is larger than the capacity of 40A, if it can help you, I hope the best setting, thank you.

To make a difference, the magnitude of the current represents 40 amps and 60 amps, respectively.

The difference between car battery 12V60Ah and 55Ah is as follows:

1. Battery capacity, the battery capacity of 12V60Ah is larger than the capacity of 55Ah.

2. The speed of electric energy conversion, the speed of 12V60Ah battery to convert electric energy is faster than that of 55Ah battery, because 60Ah battery has higher power conversion efficiency.

3. The voltage is different, the voltage of the 12V60Ah battery is larger than the voltage of the 55Ah battery.

60Ah and 55Ah are both the capacity of the battery, the unit is ampere-hours (ampere-hours), their difference is that the capacitance is 60 (discharged at a current of 60A for an hour), and the other is 55, the former is 5Ah larger than the latter

The 60as capacity is slightly larger, and the difference is minimal.

It's almost identical,,, it's just a 9 percent difference in capacity.

Yes, as long as the voltage is the same, no problem. The 12V45Ah battery can replace the 12V60Ah battery, but the time is shorter, if it is used in the car, it is necessary to consider the use of a 12V45Ah battery, will it be due toBattery capacityLeave the car halfway down, not whether it can be used or not. Of course, it is better to replace it with the original capacity or a larger capacity, so that you can run farther on a single charge.

AH is a unit of battery capacity, and similar ones like 45 and 60 will not affect the output current, and can be supplied normally. However, now the use of 60ah battery cars are generally vans, cars and other cars, this kind of car due to more electronic equipment on the power demand, it is not recommended to change small for large, large for small or the same best, but if you are emergency or have no other choice, this is no problem.

Also, in Ah, a is the unit of electric current.

h is the unit of time.

hours, together are usually called ampere-hours, and 12V45Ah means that the battery can be discharged for one hour if it is discharged at a current of 45 amperes (A) at a voltage of 12 volts (V); In the same way, 12V60Ah means that if this battery is discharged at 12V, the current discharge of 60A can last for one hour. AH This parameter can be used for reference.

Whether the 12V45Ah battery can replace the 12V60Ah battery depends on the specific situation, but in principle, it is not, no matter what electrical equipment, its power supply and load are matched, and it has been scientifically verified to be the best use state. If used as a starter starting power supply, the instantaneous discharge current of 12V45Ah is far less than that of the 60Ah battery, so that the 45Ah battery has to release more electric energy to meet the requirements, which is not only huge or even fatal damage to the battery, but also the starter is slow and difficult, and the electric energy cannot be quickly converted into kinetic energy, which will produce a large amount of heat energy, which is easy to damage the starter. Take a step back, you may not see much of a problem with it for the time being, but the battery life is greatly shortened, and you may not know when the entire system will fail, causing trouble!

can be replaced. The output voltage is the same, and the maximum output current is related to the motor power and motor load. The 12 60ah has a longer battery life, and the trolley can also speed up and increase the load.

The 12V45Ah battery can be used instead of the 12V60Ah battery, but the battery capacity is not as large as the 12 60Ah.

What you said is the starting battery of the car, it was originally 15 volts 60 ampere, I want to use 45 ampere-hours instead, it is not recommended, because the original manufacturer designed 60 ampere-hours is based on, now the power suddenly drops, if it is a new battery, it is the weather is hot, you can make up for it, once it is winter, it will cause difficulty in starting, so it is not recommended to change the battery with a small capacity.

No, the same type of battery is required to replace.

Yes, as long as the voltage is the same, no problem.

AH is the battery capacity.

units, such as 45 and 60, which are almost the same, will not affect the output current, and can be supplied normally. However, now the use of 60ah battery cars are generally vans, cars and other cars, this kind of car due to more electronic equipment on the power demand, it is not recommended to change small for large, large for small or the same best, but if you are emergency or have no other choice, this is no problem.

Also, in Ah, a is the unit of electric current.

h is the unit of time.

hours, taken together, are usually called ampere-hours, and 12V45Ah means that the battery can be discharged for one hour if discharged at a voltage of 12 volts (V) at a current of 45 amperes (A).

In the same way, 12V60Ah means that if this battery is discharged at 12V, the current discharge of 60A can last for one hour. AH This parameter can be used for reference.

Theoretically, it can be replaced, as long as it is the rated voltage of the battery.

It can be used when matched, but because the capacity of the replacement battery is a little smaller, the service life or battery life will be 25% less than the original battery, that is, the frequency of charging will be more than before. If the battery characteristics are the same, there are no other noticeable differences. So you can decide whether to use a new battery or not according to your own usage.

As long as it is also a Q-shaped battery, it can be completely replaced, but the capacity is smaller.

OK. It's just that the capacity is smaller. It does not affect the use.

You first understand the number of ** used in your car to choose the battery, and the 12V45Ah battery is not a substitute for 12V60Ah, and the current is not too large.

Brand model: Varta battery.

System: L2-400

12V60AH car battery charging for 6A 12A, charger set 3 gears (about 8A). Usually the battery of the family car is 12V, the general no-load voltage is about 13V, and the load voltage is not less than 11V, if it is lower than this voltage, it will cause difficulty in starting.

The battery can be charged by the generator while the car is driving, and if the car is parked for a long time, it is easy to cause the battery to lose power, causing the car to fail to start. The current for charging is calculated as ten percent of the battery's capacity. The battery is afraid of low temperatures, and in a low temperature environment, the capacity of the battery is lower than that at room temperature, so it is necessary to check and maintain it in time.

Note: 1. Avoid parking the car in the open-air parking lot for a long time, if it is parked for a long time, the battery must be removed and taken away to prevent the battery from being damaged by icing;

2. Avoid multiple uninterrupted starts, which will cause the battery to burn out due to excessive discharge;

3. Start the car every once in a while to charge the battery.
