How to use a safety backup battery

At many accessories stores, electrical equipment, backup battery packs are sold extremely diverse from designs, capacities to suppliers, prices vary by several hundred thousand dong between genuine and counterfeit goods. , phony goods.

Many types of standby chargers are floating, unknown origin of a few thousand to several tens of thousands of mAh, but the price is only a few hundred thousand dong, while genuine chargers with equivalent capacities cost millions of dong.

Talking about the cause of the explosion of backup charge, Associate Prof. Dr. Nguyen Truong Luyen, former official of the Institute of Engineering Physics (Hanoi University of Technology), said that the risk of explosion is very high if not used properly. come with both genuine and cheap backup battery chargers.

1. Firstly , it is possible to mention the poor quality of the battery, the battery core structure is not guaranteed. The series of genuine rechargeable batteries often use high-class Lithium-Polymer batteries. To reduce costs, many brands choose to use Lithium-ion batteries, even using counterfeit batteries, and recycling them in spare rechargeable batteries, leading to a risk of energy safety.
2. Secondly, due to improper charging. Users plug in the charger for a long time, full night or full day, resulting in a battery being hot and causing an explosion. Frequent overcharging of a backup battery can easily damage the battery if the spare battery is not equipped with protection or self-disconnection. Many users also put spare batteries in places with high temperatures, strong magnetic fields . or too high humidity, affecting quality. There are also a number of other causes such as: Machine gets wet when plugged in; voltage in the area is not stable. When plugging the charger directly into the machine, it is easy to happen short-circuiting, causing fire and explosion between the contact points.

It is important to avoid a new, fully charged battery that will affect the battery life.

How to safely use backup battery

Associate Prof. Dr. Nguyen Truong Luyen recommends that, when buying backup batteries, consumers need to select reputable brand products and reputable distributors. Need to select stores, supermarkets with names, on packaging products with warranty stamps, genuine stamps, must specify the origin. Avoid using poor quality, unknown sources of floating corners in the market.

Before charging people need to clean their hands and equipment. When using it, it is necessary to comply with the recommended regulations on capacity, charging current and charging time. Need to use the right features that the battery supports and use the right type of charger for the device.

It is important to avoid a new, fully charged battery that will affect the battery life. In order to avoid unnecessary risks, do not charge the battery overnight or for a long time without control to avoid an unstable power supply or charging for too long. Note, absolutely do not use the phone while charging the battery with 220V power because there have been many cases of accidents.

Experts also recommend that users should not buy cheap high-capacity chargers of unknown origin. These charger models are sometimes exploited in capacity, using a battery with no quality assurance or both.

Before buying, learn about the device, depending on the needs of the consumer to choose the appropriate capacity. For example, if used for phones, the size of 2,000 mAh is medium. If used for both phones and tablets, choose 4,000 - 8,000 mAh. If you add a laptop, you can choose 10,000 mAh or more.

In the process of using backup battery, people need to limit exposure to the sun or places with high temperatures, humid places. It is recommended to store the device in a dry place, avoid moisture and avoid contact with corrosive materials. Do not use detergent to clean the rechargeable battery. Store in places far away from children. If you accidentally let the battery fall into the water, you need to dry it immediately, especially in the circuit board and the electrical contact point.

How to keep your spare battery durable:

1. For the first time : Use up the available capacity of the battery then charge continuously for about 6-8 hours depending on the high or low capacity of each backup battery type.
2. 2nd charge : Charge only when the capacity of the first charge has been used and continue charging continuously for 6-8 hours.
3. 3rd charge : Proceed to charge after using up the capacity of the second charge.
4. From the 4th onwards : Do not exhaust the newly charged battery and do not charge it when the battery is full. It is best to charge when the battery is 1 bar or when the device needs to charge.
