My notebook battery is overheating

Summer is coming; the air temperature is getting higher and higher. Are you feeling too hot to bear, so does my notebook battery. Under the right circumstances, batteries could overheat, potentially causing burns, an explosion or a fire.

To understand why that happened, it’s helpful to know a little bit about how batteries work. Batteries have a negatively charged terminal and a positively charged terminal. In a battery, energy from electrochemical reactions causes electrons(negatively charged particles) to collect at the battery’s negatively charged pole. Charged particles are attracted to opposite charge, so if you connect a battery to a circuit, the electrons will flow from the negative pole, through the circuit and to the battery’s positively charged pole. In other words, the battery generates a moving charge, or electricity.

Dell and Apple Computer have been recalled large number of laptop batteries in last few years since the requirement from customer and the development of technology. There are several reasons why­ multiple laptop battery models have been recalled in the past few years. People want small, lightweight laptops that they can use for long periods. They also want their laptops to have bright screens and lots of processing power. For these reasons, laptop batteries have to be relatively small, but they also have to hold a lot of energy and last a long time.
