Identify the advantages and disadvantages of dry batteries in three steps

Three steps to distinguish the advantages and disadvantages of dry batteries In daily life, people use remote controls, radios, flashlights, electric toys, etc. to install several dry batteries. Some citizens will find that some batteries will not work in a short period of time. Regarding how to distinguish the pros and cons of dry batteries, the reporter interviewed Sun Yundong, an expert from the Municipal Quality Inspection Bureau. Experts analyze that the batteries that citizens usually use include remote controls, radios and other devices. They are generally alkaline dry batteries. Commonly used batteries are 1, 2, 5, and 7 batteries. The advantages and disadvantages of batteries can be easily determined in the following way: Look at the price. High-priced dry batteries are of good quality. Do not buy cheap batteries from unlicensed vendors. These batteries are not only short-lived, but also leak and pollute the environment. The weight of the two classes. Dry batteries of the same brand and specifications can be weighed on an electronic scale. The quality of the battery is much heavier than that of the battery. Check the appearance three times. A good dry battery will be marked with the trademark, manufacturer, battery model, nominal voltage, battery polarity, processing date, shelf life, implementation standard number, fine work, clean, and leak-free on the package. At the time of purchase, you can also check whether the product is marked with no mercury, 0% mercury, and no added mercury. Eat less, eat more, don't eat too much to charge the phone. How does bad charging habits affect the phone battery? The reporter consulted Master Lin, a senior mobile phone repairer at a certain brand mobile phone after-sales service center in the city. Calling or playing apps while charging is the same. It said that although the general mobile phone battery has a protection circuit design, the current activity will be very large when playing while charging, making the mobile phone, battery, and charger have a large load operation, so it will affect the protection circuit. Second, mobile phone batteries should not be charged for a long time. The mobile phone battery also has an overcharge protection circuit design, that is, after the charging is completed, the charging process will automatically terminate, but the battery will start the self-discharge process at the same time, resulting in a decrease in battery power. When the power drops to a certain level, start charging again, and continue to discharge and charge. Long-term high voltage will have a negative impact on the battery, which will not only shorten the battery life, but also bring safety risks. Hybrid chargers also pose a threat to the safety of mobile phone batteries. Since the output power and input power of different brands of chargers may be different, charging with different models of mobile phones may cause current instability, resulting in battery loss or damage. So how to charge correctly and safely? Lin said that in addition to using the original charger, frequent shallow charge and shallow discharge will help extend battery life than deep charge and deep discharge. Don’t think that too many recharges will damage the battery. It is not suitable for lithium batteries. Therefore, it is a good habit to have the opportunity to plug in the charging plug and it is almost impossible to pull it out during charging.
