12 What is the volts of the positive and negative poles of the 12AH battery?

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.

Classify. 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.

How it works. A lead plate filled with spongy lead was used as the negative electrode, a lead plate filled with lead dioxide was used as the positive electrode, and 22 28% dilute sulfuric acid was used as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy.

I'm afraid you are using a voltage tester to measure, that is the voltage number of the positive electrode to the ground or the negative electrode to the ground, as a battery, there is only one voltage number between the positive electrode and the negative electrode. If you introduce a grounding point to take measurements, it's completely random.

The voltage is also known as the potential difference or potential difference. Metals induce electromotive force in a complex electromagnetic field environment, so there will be a certain potential difference between the metal and the ground, which is the voltage you may be able to measure.

Summary. If the parameters of the two batteries are the same, including voltage, internal resistance, etc., a new battery with twice the original capacity will be formed. If the parameters of the two batteries are not the same, for example, one has electricity, and the other is not charged, it will form a direct discharge of the battery with electricity, so that the battery with electricity will be discharged with a large current to the battery without electricity in a short period of time, so that the battery with electricity will also have little power in a short period of time, just if the gas tire is inflated with the same as the tire with gas, but the difference with tire inflation is that because the internal resistance of the battery has increased by two times, the consequences are:

It's not as good as the energy of a charged battery, and if you have to connect it that way, the battery in the battery compartment of the appliance will flow and corrode the circuit board for a few days. In addition, there will be no major damage to electrical appliances.

What will happen to the positive and positive electrodes of the two batteries, and what will happen to the number of amperments and volts when they are connected?

Hello, dear, I'm glad to answer your <>

Answer: The positive pole and the positive pole of the two batteries, and the connection between the negative electrode and the negative electrode will form a loop. Fight quietly.

If the parameters of the two batteries are the same, including voltage, internal resistance, etc., a new battery with twice the original capacity will be formed. If the parameters of the two batteries are not the same, for example, one of them has electricity, and the other one is not charged, it will form a direct discharge of the battery with electricity, which will cause the battery with electricity to discharge the battery with high current in a short period of time, so that the battery with electricity will also have little power in a short period of time, just like if the tire with gas is inflated with the tire without air, but the difference between dust and tire inflation is that the internal resistance of the battery has increased by two times. So the consequence is that it is not as good as the energy of a battery with electricity, and if you have to connect it like that, the battery in the battery compartment of the appliance will flow and corrode the circuit board in a few days at most.

In addition, it will not cause any big losses to electrical appliances.

Summary. Battery: generally refers to lead-acid battery, which is a power storage device, when needed, it can supply direct current to the outside, volts:

It refers to the voltage of the battery, the unit is volts, generally 6V, 12V, etc., milliampere: it is the unit of current, it is 1 1000 of this unit, (I estimate that you want to ask milliampere-hour - the capacity unit of the mobile phone battery, and the capacity unit of the battery is ampere-hour, which is 1000 times that of milliampere-hour).
