The garbage battery lamp can be put in the sun to dry, as long as he is not exposed, he will not **, if there is exposure, he will**.

Forehead. Amazing brain circuits!
.Of course. The battery of the walkie-talkie should not be directly exposed to the sun. It is recommended that you use a hair dryer to dry it carefully, and pay attention to the temperature should not be hot. After blow drying, put it outside and wait for the moisture to completely dissipate, and then install it back overnight!

Of course, the walkie-talkie battery can't be put in the sun.,And this should still be dangerous.,It's best not to put it in a place where it bursts.。
-
The infeasible temperature will rise to a certain level, which will be very dangerous.
-
The battery is generally not exposed to the sun. If he is already leaking, it cannot be used.
-
What a magical brain circuit.
-
All batteries are not very suitable for drying in the sun, and it is easy to cause some dangers due to too high temperature.
-
It is okay to leave the battery of the walkie-talkie to dry in the sun, but be careful not to leave it for too long, and it cannot be placed directly on the ground.
-
The battery of the walkie-talkie, you can put it in the sun, but do not expose it to the sun, you can dry it for a while.
-
Can walkie-talkie batteries be left in the sun to dry? No, you cannot.
-
Can a walkie-talkie battery be put in the sun? You are delicious and don't get sunburned, because it will produce **.
-
Can a walkie-talkie battery be put in the sun? It is impossible to ask anyone who is afraid of it, and who is in danger of exploding.
-
Can walkie-talkie batteries be left in the sun to dry? If you don't want this, you can't do it.

The big boss (Wu) is quite famous, there are more people, and some of the things he studies are more cutting-edge, but I personally feel that he is more pragmatic and weaker in practice.

As we all know, with the rapid development of the times, new energy vehicles will have a great possibility to replace the current fuel vehicles in the near future, but this is all a later story. At present, if you want to choose a new energy vehicle, the first thing you must look at is the mileage, in other words, the power reserve of the power battery of the car, how long can it run.
Most of the new energy pure electric vehicles on the market now have a range of about 400 kilometers, and it can also be said that 400 kilometers is the passing line for pure electric vehicles. On the other hand, if you are above 400 km, then your sales will not be bad. Recently, foreign media reported that researchers from the Massachusetts Institute of Technology proposed a new electrode design for the battery, which will improve the power reserve of the battery.
We all know that the electrode is one of the most important parts of the battery, and if you want to use the power in the battery, you must export and import it through the electrode, and in this process, most of the current electrode materials will escape from the power. The new electrode design proposed by the Massachusetts Institute of Technology is designed to reduce the escape of electricity.
The Massachusetts Institute of Technology (MIT) has proposed a new concept of electrodes in which the new electrodes will rely more on the redox power of oxygen during the battery cycle, preventing the power from escaping through the metal material of the electrode. At the same time, in order to prevent oxygen ions from escaping from the cathode particles, the researchers used molten salt for high-temperature surface treatment to form a protective layer on the surface of the metal oxide particles rich in manganese and lithium, thereby greatly reducing the loss of oxygen. At the same weight, the current electrode version offers at least 50% more energy storage and better cycling stability.
Of course, the new electrode will not only improve battery energy storage, it will also reduce the use of expensive and toxic nickel and cobalt and use cheaper manganese, which may be one-fifth the cost of conventional electrodes. In addition, the weight of the new electrodes is only a quarter of that of traditional lithium-ion battery electrodes, which means that the new design will greatly increase the density of the battery, and if the new battery is placed on an electric vehicle, it will have a much higher range than the current battery.
And this new electrode design will also be better in terms of safety, because the design abandons the use of traditional liquid or polymer gel electrolyte materials, in the charge and discharge cycle of the battery, lithium ions move back and forth through the electrolyte, using an all-solid electrolyte may be safer than a liquid electrolyte, because the liquid electrolyte is highly volatile, so this is also the root cause of lithium batteries**.
So far, research on the new electrode is still in the laboratory production stage, and the MIT research team indicates that it will be produced on a large scale as soon as possible. It is foreseeable that if the new battery can be commercialized in the near future, for example in the field of electric vehicles, then consumers will most likely buy electric vehicles with a range comparable to that of gasoline vehicles!
Refer to the instruction manual of the North Peak walkie-talkie.
This is adjusted frequency stepping.
It is generally divided into several grades, namely: 5,625,1m (1m refers to one decimal place). >>>More
One, no. The length of the antenna should be a multiple of half of the frequency, but the length is not suitable and can be transmitted, but the matching degree is not good, and the quality is reduced. The problem of communication distance is actually the problem of antenna height. >>>More
You can contact the customer service staff of Shentong company, let them check the intranet, generally there are weight scanning records of each site on the intranet, it can be seen that it is less than **, the customer indicated 19 units on the face sheet, you can complain to their head office, ask the delivery site to provide a receipt as evidence, plus there is a weight difference, there is a possibility of acceptance. However, no matter which courier company, the general recipient signed for the receipt at the moment, there was no rejection, and the signature was sent to the Internet, which is not easy to complain successfully.
With the rapid development of the domestic economy, the number of walkie-talkie brands has surged, and there are hundreds of well-known and unknown domestic walkie-talkie brands alone. However, although there are not many of the top ten domestic walkie-talkie brands entering the international market, they are all well-known brands. For example, Hytera's walkie-talkie products have been distributed in more than 100 countries and regions around the world, and have nearly 30 branches around the world. In the world, the company's product shipments ranked second.
