How to charge the new battery 72v for the third time, can it be charged for nine hours?

Friend, the new battery is 72V, the third charge is not satisfied after nine hours of charging, in this case, you can check whether the charger and the battery are hot, if it is normal, it is because the charger power is too small to cause a long charging time, you can continue to charge and wait for the green light to be.

Hope it helps!!

The new battery is 72 volts, the third charge is OK, and it is not satisfied after 9 hours of charging, that is because there may be problems with your battery, generally it does not need to be charged for so long, and if it is generally charged for so long, it must be fully charged, so there is no need to flush it after a few hours.

The new battery 72V is charged at any time, and it is normal to charge it for more than 24 hours if there is no power.

Could it be that the charger does not match? This is also possible, because we know that sometimes the charger may charge the battery if it is not good, so it is recommended to unplug it and use it first.

Charge for a while until it is fully charged, if you can't charge it every time, the battery will not be charged.

The main thing is that you see if the current of your charger is too small, and if the current is too small, the charging time will not be enough.

There should be a charging indicator light when charging, if the paper indicator turns green, you don't need to charge it again.

Check that the charger is compatible with the battery.

Hello. Because many places of the new battery have not yet started chemical reactions, of course, they must be used for charging, and the charging battery and discharge performance are very good.

If it has been charged for nine hours and it is not full, stop for a while, and then stop and recharge again.

Of course, it can be rushed.

Like this new battery, the charging time is generally more than ten hours.

Then continue to rush, the question is that you have to look at the size of the battery capacity, and whether the charging speed of your charger matches? If the charger is too slow, it is slow.

If you don't make a new battery, it means that the battery is refurbished, and you'd better test it.

Generally, it needs to be charged for more than 12 hours.

A battery is a battery that can be recharged after discharging. There are lead-acid batteries, nickel-iron batteries and nickel-cadmium batteries. The positive electrode of the lead-acid battery is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution.

When discharging (using), the positive and negative electrodes react with sulfuric acid to form lead sulfate, and when the concentration of sulfuric acid solution drops to a certain level, it must be charged. When charging with an external power source, the electrode and solution can be restored to their original state, and they can be used again after charging.

1. Ordinary battery: The plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; The disadvantages are low specific energy (i.e. the amount of electrical energy stored per kilogram of battery), short service life, and frequent routine maintenance.

2. Dry-charged battery: the full name is dry-charged lead-acid battery, its main feature is that the negative plate has a high power storage capacity, in a completely dry state, it can save the power obtained within two years, when used, only need to add electrolyte, and wait for 20-30 minutes to use.

3. Maintenance-free battery: Due to the advantages of its own structure, the consumption of electrolyte is very small, and there is basically no need to replenish distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge.

The service life is generally twice that of ordinary batteries.

There are also two types of maintenance-free batteries on the market: the first one is to add electrolyte at one time when purchased, and no maintenance is required in later use (add replenishment solution); The other is that the battery itself has been added with electrolyte and sealed at the factory, and the user cannot add refill liquid at all.

Hello, remember to adopt it this time.
