　　Although many batteries are not durable now and can only be used for 1~2 years, we can buy more durable batteries if we pay attention to these three points when buying batteries, and it is not a problem to use them for 3~4 years.from e-bike battery charging tips Looking at the development prospects, the future will always bring positive effects. https://www.chamrider-battery.com/

　　Point 1: Try to choose high-end batteries.

　　At present, the batteries of electric vehicles have been divided into three grades, high, middle and low, especially the low-grade batteries. Most of them directly use recycled lead, because the price of this battery is cheap, and battery brands also use this battery to seize the market.

　　Why can the battery of electric vehicle only be used for 2 years? The key to these two reasons is how to buy a durable battery-driving.

　　If you want to choose a durable battery, you need to avoid this low-end battery, but try to choose a high-end battery. High-end batteries often use primary lead, and there are some black technologies, such as graphene batteries, which add alloy materials and graphene, so the battery has better conductivity and longer service life.

　　Point 2: Choose a heavier battery.

　　If you don’t know which battery is better, there is a simpler way, that is, look at the net weight of the battery. Under the premise of the same capacity, which battery is heavier, then this battery is definitely more durable.

　　Why can the battery of electric vehicle only be used for 2 years? The key to these two reasons is how to buy a durable battery-driving.

　　As we all know, the battery of electric vehicle is mainly composed of three parts, namely, battery shell, electrolyte and electrode plate. If the battery with the same capacity is heavier, its electrode plate thickness will increase, so it will be more corrosion-resistant and can make the battery more durable.

　　Point 3: Try to choose a large-capacity battery.

　　When buying an electric car, everyone has a budget within the budget, and choose a battery with large capacity as much as possible, such as the same size. Ordinary lead-acid batteries are only 20Ah, while graphene batteries can reach 23Ah, so this battery can not only run better, but also store more electricity.

　　Why can the battery of electric vehicle only be used for 2 years? The key to these two reasons is how to buy a durable battery-driving.

　　On the one hand, a large-capacity battery can make the electric vehicle run farther, on the other hand, it can also reduce the charging times. We know that the service life of the battery is mainly determined by the number of charging and discharging cycles. If the charging times are reduced, the service life of the battery will be relatively extended.

　　Summary:

　　The battery of electric vehicle is very important. The reason why the battery is not durable in recent years is because of the battery shortage and the use of recycled lead. Therefore, if we want to prolong the service life of the battery and buy a more durable battery, we just need to avoid these problems. Therefore, when buying a durable battery, try to choose a high-end battery, a battery with heavier weight and a battery with larger capacity, which can make your battery last for two years.

Russian President Vladimir Putin said on the 13th that he would redeploy troops on the border between Russia and Finland in response to Finland’s accession to NATO, UPI reported on March 13.

Reported that Putin said in an interview with Russian state media that from the perspective of safeguarding national interests, the actions of Finland and Sweden are absolutely meaningless.

We used to have a good relationship with Finland on the whole, he said. It’s perfect. The two countries do not covet each other, especially territorial claims, let alone other areas. We didn’t even have troops at the border; we withdrew all our troops from the Finnish border.

But this is their decision, Putin said. Now that they have decided that we did not have troops there in the past, we will have them now.

It is reported that in 2022, shortly after Russia sent troops to Ukraine, Finland and Sweden applied to join NATO. Finland became a member of NATO in April last year, and Sweden did not formally join until last week because of opposition from Hungary and Turkey.

Putin’s remarks came after Finnish Prime Minister Peter Riolpo told the European Parliament in Strasbourg that other EU countries must follow Finland’s example and strengthen security in marginal areas. (compiled by Wang Dongdong)

Putin warns the West: ready for nuclear war

Russian President Vladimir Putin has warned the West that Russia is technically ready for a nuclear war and that if the United States sends troops to Ukraine, it will be seen as a major escalation of the war, Reuters reported on March 13.

Putin accepted a joint interview with Russia-1 Channel and Russian News Agency on the 12th. The program about this interview was officially broadcast on the 13th.

In response to the question of whether Russia is really ready to fight a nuclear war, Putin said: from the perspective of military technology, we are certainly ready, the report said.

Putin pointed out that the United States understands that if it deploys US troops on Russian territory or in Ukraine, Russia will regard this as intervention. So while I don’t think it’s all in a hurry to [nuclear confrontation” target=_blank>, we are ready for it, he said.

The conflict in Ukraine triggered the most serious crisis in relations between Russia and the West since the Cuban missile crisis in 1962. Putin has repeatedly warned that if the West sends troops to fight in Ukraine, it could lead to a nuclear war.

In the interview, Putin reiterated that the use of nuclear weapons is something already stated in the Kremlin’s nuclear policy, which sets out the possible use of nuclear weapons by Russia.

Putin said: weapons exist to use them. We have our own principles.

The report also said that for the conflict in Ukraine, which has lasted for two years, Putin said that Russia is ready to hold serious talks on the Ukraine issue.

Putin said: Russia is ready to negotiate on Ukraine, but the negotiations should be based on reality, not on desire after the use of psychotropic substances.

Reuters reported last month that Putin’s proposal to cease fire in Ukraine to freeze the war was rejected by the United States after middlemen between Russia and the United States.

According to the report, he also said in an interview that if the United States conducts a nuclear test, Russia may do the same.

We may not have to consider this issue, but I do not rule out the possibility that we will do the same, he said. (compiled by Longjun)

According to a report by the German News TV channel on March 14, a latest report released by the American Institute for War Studies stated that due to lack of ammunition and supplies, the Ukrainian defense line may be more fragile than the impression given by the relatively slow advancement of the Russian army in various places.

The report said that in order to curb the continued advancement of the Russian army, Ukraine currently has to use the small amount of existing materials as efficiently as possible. The Institute for War Studies wrote: The Ukrainian army concentrated its supplies in the areas of the line where the Russian army encountered the most fierce attack, which would lead to poor defense in other areas, allowing the Russian army to launch surprise attacks there and achieve breakthroughs.

The American think tank also quoted a report in the magazine Der Spiegel. A Ukraine officer said in a report that in secondary battlefields such as Kharkiv or Vukhredar, which are currently receiving little attention, the situation of troops, weapons and ammunition is very bad. An artillery commander said: We can’t hold on like this for long. The analysis report wrote that the reason why some Ukrainian troops were able to hold their positions with limited ammunition and supplies was only because the Russian army did not attack with all its strength.

The Institute for War Studies warned that the Russian army did not attack areas where Ukraine was extremely poorly guarded, concealing the risks there. In other words, as long as the Russian army launches large-scale attacks in these areas, it will expose the current situation that the Ukrainian army is unable to resist due to lack of ammunition. Ukraine’s Armed Forces Commander-in-Chief Sersky warned on a social platform telegram that Russian troops may break into the depths of the Ukrainian defense line.

The Institute for War Studies said the words of Sersky and other Ukrainian commanders suggested that if the Russian army stepped up its offensive, it could break through and shake previously stable areas in a short period of time.

The report concluded that the current defense line is likely to be unstable. It is crucial for the West to transfer resources to the Ukrainian army as soon as possible to prevent Russian troops from waiting for opportunities to break through weak defensive areas on the front line.
