20AH charger for battery car Charge 12AN battery Does charging have an impact?

Battery car charging has an impact, and the battery will heat up and deform after a long time, reducing the battery life, which is very dangerous.

1. The battery of the electric vehicle charger 20ah and 12AN is equivalent to fast charging. Grasp the time, up to three hours, regardless of whether the light is green or not, it cannot be charged.

2. Long-term use of electric vehicle charger 20ah, 12an battery, easy to cause battery heating and deformation, shorten the life.

3. Long-term use of electric vehicle charger 20ah, 12an battery, fast charging, it is not easy to charge the battery to a full level.

4. It is best to buy a charger suitable for the battery, the comparison between the charger and the battery, is not cost-effective, and it is also dangerous.

A 60v12ah charger can definitely charge a 60v20ah battery; A 60v20ah charger can definitely charge a 60v12ah battery; Generally, chargers are not expressed in "ah"; The accurate expression should be the output voltage **v, current **ma, or current **a; Maybe the charger you bought is specifically for charging the battery of an electric vehicle, so it is expressed in ah (amps, hours); If you use a 60v12ah charger to give a 60v20ah battery, it will take a little longer because of its small current; In terms of time, the charging time of small current is slightly longer, and the battery is used for a long time; The same goes for a 60v20ah charger for a 60v12ah battery; The time is slightly shorter; There is nothing wrong with that.

12A is the capacity value of the battery, and 48V is the voltage of the battery, which is not directly related to the size of the charger. When the charger is large (refers to the current during charging), the charging time can be shortened, and the charging time will be more if it is smaller. The key is that the current chargers are all automatic, and when the capacity value of the battery reaches the rated value of the charger, it will automatically stop charging.

A 12ah charger can charge a 20ah battery. It has an impact on the service life of the battery. The 12ah charger charges a 20ah battery, and it takes longer to fully charge the battery.

When a 12ah charger is charged with a 20ah battery.

Due to the small charging current of the 12ah charger, the battery will be in an undercharged state for a long time, resulting in a decrease in the rated current value of the battery and unstable power output, which will cause the vehicle's battery life to be shortened and the climbing ability to decrease. Select the charger by the rated capacity of the battery. This is good for the battery and good for the use of the vehicle.

First of all, we have to interpret what the meaning of a 12ah charger is12Ah means that the charger can charge your battery to 12A (amps) per hour (theoretically).Therefore, if your battery is 20ah, theoretically it only needs to be charged for 2 hours, but most of the current chargers exaggerate their product performance, so they need to be charged for at least 3 hours

Also, the battery is generally not fully charged at one time, and it takes at least 2 or more timesIt is recommended to buy a multimeter to measure electricity with peace of mind

There is a problem with this unit. If the charger does not have AH as a unit, it is XXA, if it can automatically adjust the current, there is no problem, if it is 12A fixed current, the charging current is too large, it is easy to cause high temperature, the electrolyte electrolysis is fast, and the battery life will be shortened.

Generally, it is best to control the charging in about 4 hours to fully charge the battery, for example, yours is 20ah, just 20 4=5A or so.

The charger of 12he can charge 20 rechargeable batteries, this should be possible, but I think this should be for the battery, Ferguson is still relatively large, all artificial evidence must still pay attention to safety, because I think this should still be deservedly harmful, all think that this is the case, or need some management, in order to achieve a better use effect, otherwise for its practicality, it should still be more harmful.

It can be charged, and there is no other effect on the battery, that is, the charging speed and time have an effect.

The 12Ah charger generally has a charging current of about 2A, and the charging time is more than 10 hours to charge the 20Ah battery. Charge normally.

Yes, but efficiency isn't so good. I can't charge it at full efficiency, but it's not like I can't.

12 Ah and 20Ah both indicate the capacity of the battery, and A indicates the size of the charging current. Generally speaking, the charging current is suitable for charging a 12Ah battery, if the 20Ah battery is charged, the current is a little smaller, and the charging time should reach 14 hours.

The voltage of the charger must be equal to the battery voltage, that is, 4 sections for 48V, 5 sections for 60V, etc., in addition, the charger is generally also marked for battery charging suitable for xx ampere, and some are marked with a range, such as, 48V, 12 14 Ampere, 48V, 20 24 Ampere, etc.

An electric vehicle charger is a charging device that is specially configured for the battery of an electric bicycle.

Classification of chargers: With and without power frequency (50 Hz) transformers, it can be divided into two categories. Freight three-wheel chargers generally use chargers with power frequency transformers, which are large in size, heavy in weight and consume electricity, but reliable and cheap; Electric bicycles and electric motorcycles use so-called switching power chargers, which are power-saving and efficient, but they are easy to break.

Prevent the battery from overcharging:

1. The overcharging of the battery produces a large amount of gas to wash the plate, which accelerates the shedding of the active material on the plate and shortens the life of the battery.

2. The overcharging of the battery accelerates water loss, resulting in the drying up of the electrolyte and the increase of the battery temperature, resulting in thermal runaway, plate expansion and shell deformation.

Prevent battery over-discharge:

Pay attention to skills in the use of battery cars, and also prolong the service life of the battery. Long-term deep discharge will cause the battery plate to soften and shorten the service life.

1. Prevent high-current discharge, and try to help with your feet when starting, uphill and headwind.

2. Prevent long-term discharge, and do not drive after discharging frequently. Charge when the charge level is 1 2 low.

Prevent battery loss:

For batteries that have been left unused for a long time, they should be fully charged once a month, and it is generally better to continue to float for 5 hours after the charger turns red to green.

The voltage of the charger must be equal to the battery voltage, that is, 4 sections for 48V, 5 sections for 60V, etc., in addition, the charger is generally also marked for battery charging suitable for xx ampere, and some are marked with a range, such as, 48V, 12 14 Ampere, 48V, 20 24 Ampere, etc.

No.

The output current of 48V12A charger and 48V20A charger is not the same, 48 12 output current is about that, 48 20 output is around and around, and then, according to this, it can be seen that it can definitely be used, but it is necessary to consider whether to use it often or occasionally, if it is used occasionally, it is no problem, if it is to be used for a long time, it will not work.

Due to the different sizes of the batteries, the charging current and the lamp changing current are not the same.

Precautions. Because the charger is too small to be fully charged, the active material in the battery will not reach the optimal state for a long time, and it will be scrapped prematurely, or the active material will fall off due to overcharging, and the capacity will be reduced.

Therefore, it is still best to charge with a matching charger, not too high and not too low. This will prolong the battery life.

Finally, you must pay attention to the charging time, which is generally 6 to 8 hours in summer and 10 to 12 hours in winter, so as not to affect the battery life.

A 12ah charger can charge a 20ah battery.

It has an impact on the service life of the battery.

The charger of 1,12ah can charge a battery of 20ah.

It's just that this way charging takes longer to fully charge the battery.

When the 2,12ah charger is charged to the 20ah battery, due to the small charging current of the 12ah charger, the battery will be in an undercharged state for a long time, resulting in a decrease in the rated current value of the battery and unstable power output, which will cause the vehicle's battery life to be shortened and the climbing ability to decrease.

Therefore, the best thing to do is to choose the charger according to the rated capacity of the battery. This is good for the battery and good for the use of the vehicle.

First of all, we must interpret 12ah

What is the significance of the charger.

12Ah means that the charger can charge your battery to 12A (amps) per hour (theoretically).

So if your battery is.

20ah words.

Theoretically, just charge.

hours on the line. But most of today's chargers exaggerate the performance of their products.

Therefore, it is necessary to at least charge.

hours are fine. And also.

Batteries are generally not fully charged in one go.

At least. 2 or more times is required.

It is recommended to buy a multimeter to measure electricity with peace of mind

This is possible. At present, the lithium batteries used in electric bicycles include ternary lithium-ion batteries, lithium manganese oxide batteries, and lithium iron phosphate batteries. The latter two are the most used, among which lithium iron phosphate batteries are relatively safe, but lithium manganese oxide batteries are more affordable.

When consumers buy a new electric vehicle, the battery and the body are separated, and the car dealership will generally install them together on the spot.

It is recommended to buy a 3C certified battery, and its product certificate will indicate the type, manufacturer, capacity, and model information of the battery. The factory battery should be consistent with the 3C certificate and the certificate. In use, if the battery is to be replaced, it should also be replaced with the same or similar type as on the certificate, including brand, model, and capacity.

Whether the vehicle is adaptable, whether the charger is adaptable, and whether there are good charging habits will affect the battery life. It can be charged when there is 30% of the battery remaining, and it will stop charging when it turns green. Do not charge for too long and do not leave it while charging.

Batteries that have not been used for a long time should be disconnected from the circuit switch between the whole vehicle and the battery, and charged regularly every month.

No, because the output current of the 20A charger is much larger than that of 12A, and the battery is the most taboo for high-current charging, high-current charging will cause the battery temperature to be too high, and the temperature is too high to have a great impact.

Yes, the difference between the two is that the charging current is not the same, the charging current of 20A is larger than that of 12A, so that your charging time will be shortened a little, for example, the charging of 12A in the past is assumed to be 5 hours, then you may only take about three hours to charge with 20A. However, it is still recommended to use the original charger, which is good for battery life.

The EV charging bottle charger is 20A, which can be charged with a 12A charger.

It can be used, but pay attention to the charging time, a 20 amp charger has a larger output charging current than a 12 amp, and the relatively short charging time becomes full.

Yes, and the charging speed is faster than using 12A, the disadvantage is that the charging current is larger, and long-term use will shorten the battery life.

It is a 12ah battery, which should be charged with a charger with the maximum output current of the charger, and a 20ah battery, which should be charged with a charger with the maximum output current of the charger. In actual use, it is less than this value.

If the output current of the charger is too large, the battery is easy to overheat during charging, which will harm the battery and reduce the life of the battery. The output current of the charger is too small, and the charging time is prolonged. FYI.

Then it's okay to use it occasionally, but not for a long time, because his current is a bit large. After a long time, it is easy to cause damage to the battery.

There is no problem with emergency charging once, and after a long period of use, the battery power will be significantly reduced and the mileage of the battery car will be significantly shortened.

The big one can't charge the small one, and the small one can charge the big one, but the charging will be slower.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

Depending on your problem, we have the following solutions:

If the charger of your electric car is 20A charging current, then it is possible to charge the 12A battery, as long as it is the same voltage, this current is actually not much different, because this charger is mainly constant voltage charging, as long as it is the same voltage, this can be charged, and the capacity of this battery has little impact on the choice of nitrogen, but the speed of nitrogen filling is different, if it is a 20A battery charging time will be longer, The charging speed of the 12 amp battery is shorter.

I hope my answer will be helpful to you.
