What should be the voltage of the new No. 5 1 5V Nanfu battery?

The voltage of the new battery is generally around the center, and the reason why your battery still has 1,5V is because the voltage of the multimeter is high resistance, much greater than the internal resistance of the battery.

Measure the data yourself:

That is to say, as long as it is a new battery, (depending on the production date) how much current A depends on the circuit design, A=U R

Carbon batteries provide very small currents, measured in milliamps.

Alkaline batteries can provide a relatively large current point.

Rechargeable batteries provide more current.

I just measured the purple rice no-load, and the load did not feel useless without Nanfu. If you take it down and measure it, it will not be accurate, and you have to use the battery to measure.

In addition, 1 mouse was measured without load.

The shaver 2 sections can be used normally without load.

The Nanfu No. 5 battery is 1500 mAh.

The rated voltage of Nanfu No. 5 primary battery (alkaline battery, shaped ring technology) is 1500 mAh in total. It can be used in household devices such as electric toys, razors, remote controls, etc.

Battery disposal

First of all, you can classify the used batteries. Smash the waste battery, peel off the outer layer of zinc shell and iron sheet, and then take out the copper cap and graphite. These things can be processed and reprocessed, and waste can also be turned into treasure.

The graphite rod can be washed and dried to be used as an electrode. Peeled zinc shells can be used for many purposes after washing, generally being processed into zinc pellets first and then processed. The same is true for copper sheets, which are washed with hot water and processed, just like our ordinary copper.

In fact, used batteries are not wasted, they are just misplaced resources. However, the cost of misplacing used batteries is enormous. We have to start from ourselves, pay attention to every waste battery around us, and resolutely not let it stay in the wrong place.

Protecting the environment is also a reflection of our own quality, just like the impact of batteries, although a small piece, but the impact of throwing it on the land is huge. Our behavior, too, will change if we persevere.

Hazards of littering batteries

1. Littering of waste batteries is very serious to the environment, and a battery can pollute 60,000 cubic meters of water.

2. A No. 1 battery rots in the soil, which can make one square meter of land lose its use value.

3. Waste batteries are also very harmful to people's bodies. A battery is a device that converts chemical energy into electrical energy in a cup, trough or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It has a positive electrode and a negative electrode.

Nanfu No. 5 mercury-free alkaline battery cannot be charged. 1. First of all, in terms of type, alkaline batteries are classified into primary batteries, which are also primary batteries. 2. From a technical point of view, alkaline battery charging is only partial charging, which is generally called "regeneration", and the concept of "regeneration" further illustrates that the charging characteristics of alkaline batteries are different from the real charging of rechargeable batteries.

The limitations of regenerative charging and discharging and the short cycle life determine that the regeneration of alkaline batteries is very uneconomical. In order to ensure the successful regeneration of alkaline batteries, the following conditions must be met: 1. Discharge the initial capacity of the battery at most 30% under the condition of moderate discharge rate, and the discharge should not be lower than that, so that regeneration is possible.

When the discharge capacity exceeds 30%, manganese dioxide is produced, which prevents further regeneration. 2. The user can purchase one of the above special chargers to regenerate. Under normal circumstances, the charger of nickel-cadmium and nickel-metal hydride batteries cannot be used to charge alkaline manganese batteries, because the charging current of this charger is too high, which may cause gas to be generated inside the battery, and if the gas is flushed out of the safety valve, it will leak.

Further, if the safety valve loses its function, it can even happen**. Defective molds rarely happen in production, but they do happen, especially if the battery is not used correctly. 3. The time required for regeneration (about 12 hours) is beyond the discharge time (about 1 hour).

After cycles, the capacity of the battery will be reduced to 50% of the initial capacity. 5. The special equipment needs more than three batteries to be connected, if the capacity of the battery is inconsistent, there will be other problems after regeneration, which may lead to a negative battery voltage, if the regenerated battery and the unused battery are used together, it will be more dangerous. The inversion of the battery causes hydrogen to be generated inside the battery, which is in danger of generating high pressure, resulting in leakage and even **.

In short: a single battery regeneration over a long period of time is not only uneconomical, but also carries a certain risk, and if so, the question "can alkaline batteries be charged" is not a technical question. In order to avoid danger, it is best to use unused primary or secondary batteries (accumulators) and not to regenerate primary batteries.

The voltage of the new No. 5 Nanfu battery is exceeded, but is lower. The data is based on the measurement of the MF47 analogue multimeter.

After a period of time, it is measured with a multimeter, that is because the battery will have a certain amount of recirculation after a period of time, and the internal resistance of the multimeter is much larger than that of the battery, so it is displayed. If this battery is connected to a high-power consumer, the voltage will be much lower, for example, or even lower.

The current of Nanfu battery 4 series is determined according to the electrical equipment, if it is a new Nanfu battery, the limit current can reach the amperage level, but the discharge time will be very short, unless it is used for high-power flashlights or shavers and other high-current occasions. Electrical appliances generally cannot reach such a large current, only 500mA or less.

Summary. Hello, long waiting. The date on Nanfu battery is the date of manufacture.

The battery is chemically reacted through its internal positive and negative electrodes, and the positive and negative electrode materials are chemically reactive all the time because of the presence of trace amounts of impurity elements, consuming active substances, and the battery is stored for a long time, the active substances are reduced, and the electric capacity falls, and there will be weak current or no power that we see. Generally speaking, the shelf life of ordinary batteries is 2 years, and the shelf life of alkaline batteries is 3 years. For consumers who are looking for battery performance, it is recommended to buy alkaline batteries.
