Common battery to choose methods of digital devices

Source: 2020 - 04 - 14 hits: through the time how to choose an ordinary digital equipment batteries? First of all, we say we are the most commonly used electronic equipment, mobile phone, now the high-end products, MP4, such as laptops, apple mobile phone, is made up of polymer battery, we simply say that so-called soft package, this benefit is not easy explosion, high capacity, voltage, charge and discharge cycle life, and so on, are better than the liquid battery. Battery effective charge is 500 times, two hundred times the so-called waste battery is not, of course is not to say that many times, but the charging quality, full of electricity use shorter time than before, the original pool can suggest you buy a mobile phone battery, factory production quality guarantee and warranty service, if you use fake batteries, not only has safe hidden trouble, it is hard to get compensation in the event of accident. Now smart phone battery time is far lower than before the function of the machine, most smartphones are charging every day, if you use frequently, even many times need to charge it with electricity, easy to charge, at the same time make up the mobile phone usage time is short, mobile power supply has become the user's preferred, then the battery of mobile power supply will be better? General mobile power use of two kinds: 18650 and polymers, they are all lithium-ion batteries, 18650 is cylindrical, after the combination of product volume and weight will be bigger; Polymer can be flat, diluent, polymer lithium battery capacity, small ( Thin) , the most important is safe ( Don't explode, most can only play) , the technology is more and more mature now, the user, if you need to purchase a mobile power supply suggest buy products using polymer battery. Notebook computer is equipped with nickel-cadmium battery for the first time, but the battery has a 'memory effect', must each charge before discharge, use is not very convenient, the battery has a large volume, weight, small volume, short service life and so on shortcomings, therefore has been abandoned by the market. Later appeared equally 'memory effect of nickel metal hydride batteries, and gradually eliminated by the market. The mainstream of the market at present is the lithium ion battery and lithium polymer batteries, including lithium ion battery has small volume, light weight, large capacity, low memory effect, short charging time, etc. However, polymer lithium battery with high energy density, small volume, ultra-thin, lightweight and high security obvious advantages. Apple laptops, for example, the use of polymer lithium battery is very thin, but the battery life is not short. This is a new type of battery. Therefore, laptop battery can choose according to their actual needs. If people expect more economic, lithium ion battery capacity is larger, more durable, cheaper, so the lithium ion battery is a better choice. If they have higher requirements for weight and safety, they can choose to lithium polymer battery.
