Can Electric Bike Batteries Be Repaired?

Lithium battery has a service life like any other battery, the service life of lithium battery is measured by the number of charge and discharge, reaching a certain number of charge and discharge of the lithium battery will have completed its life as a battery. As with all batteries, a battery that has completed its life can only be discarded.


When does the battery of an electric bicycle need to be replaced?


1. The battery is full when it is charged and dead when it is used


If the battery is suddenly fully charged in one or two hours, or even in a few minutes, and does not run much distance, then it may be due to the following two reasons: First, a small battery in the battery group has failed, and it is difficult to repair the small battery itself, so the battery can only be scrapped. Second, the battery capacity is shrinking and the power storage function is almost lost. At this time, the electric car battery is basically scrapped.

2. Using more than three years, the performance drops sharply


The capacity decay of lead-acid battery is basically irreversible, and all parts of the battery over three years have basically reached a deteriorated condition, and this deterioration has a trend of gradually accelerating, and soon it will completely lose its charging and discharging capacity. Some electric car users will choose to try to repair the battery of the electric car, if the battery is still unable to save power after repair, this time it means that the battery is scrapped.


3. Charging heat, battery bulging phenomenon


If the battery charging heat is serious, even the shell is very hot, excluding the battery quality problems, the probability of life is also exhausted. The reason for the heat is the active material on the pole plate is seriously off, the internal resistance increases, the heat increases. At this time, if you open the battery safety valve to check, you will see that the electrolyte is "black" and cannot be repaired in case of serious failure. At this time, the battery self-discharge quickly, sometimes after charging soon after the power is dead. Severe will make the battery drum, and even the battery shell, the line will also appear burning, very dangerous.


4. Battery capacity is less than 60% of the normal capacity


Battery in normal use, the capacity will be normal decay, to 48/12 for example, the new battery 40 km range is relatively normal, once when fully charged can not run 20 km, that means that the battery components have begun to appear problems, a variety of performance has dropped significantly, the performance is extremely unstable, may cause adverse consequences such as charging fever deformation.


E-bicycle battery safety issues should not be ignored, we must always pay attention to the battery situation of electric bicycles, prevention is better than cure.

THE BEST USE OF LED VANITY MIRRORS

图片
The lighting capability of  LED Mirrors  is almost similar to natural lights. This mirror serves the dual purpose of making a place look beautiful and assistance in self-grooming to people. However, they are more acknowledged for decorating the place. They give a clear vision and are feasible to view yourself than any other form of lighting. They are not only used at homes but in offices, hotels, and boutiques. These mirrors are brilliant to uplift the aura of the place. They provide a classy environment with high energy efficiency. The environmentally friendly characteristic makes them extremely desirable.    WHAT IS AN LED MIRROR? An LED mirror in simple terms is a mirror with the addition of LED bulbs. This could be anything from strip lights around the side of the mirror to create a ‘back-lit’ effect or bulbs straight on the front to create a vintage vanity LED mirror style.  LED mirrors come in all shapes, sizes and styles so you’ll always be able to find one that suits the space

Benefits of Using Body Lotions

  You should never neglect your body care and we recommend using a body lotion.   Many women tend to follow a multi-step facial skincare routine, however, the opposite is true for our bodies, which we often neglect - this leads to problems such as dryness, cellulite and even wrinkles, and we should pay more attention to  body care .     Body Lotion Why and how does dry skin happen? There are a range of reasons why your skin may be prone to dryness.   In the winter.  Your skin is especially prone to dryness in the winter months. The cooler months - and the cold air and wind that come with them - can dry out your skin. In addition, enjoying hot showers and/or heaters can also cause dry skin. That's because they remove moisture from your skin, making it dry and saggy.   In the summer.  It's not just the cold that can dry out your skin. Summer often brings some unwanted dryness too! High temperatures, UV rays and frequent showers can dry out your skin. Dehydrating your skin.   Life

Difference Between Reverse Osmosis and Nanofiltration

图片
  While reverse osmosis (RO) and nanofiltration (NF) are very similar, they can be distinguished by the size of particles that can be removed or rejected. In contrast, RO and NF are capable of removing finer contaminants than MF and UF, and applications include removal of hardness, nitrate, sulfate, total dissolved solids, heavy metals, radionuclides, and organic macromolecules from process and waste streams. Difference Between Reverse Osmosis and Nanofiltration Reverse Osmosis RO membrane  is the best of all membrane filtration and purification systems, with extremely small pores capable of removing particles as small as 0.1 nanometers (0.0001 microns). RO has been around since the 1950s and is primarily used for desalination, such as producing potable or brackish water from seawater. other applications for RO include filtering process water for industrial applications, such as the printing industry, to maintain optimal equipment performance. ro membranes are very effective at removin
