According to statistics, accessory manufacturers mainly apply three main battery core technologies on backup charger lines on the market, including Lithium-polymer (Li-Po), Lithium-ion (Li-ion) and cell core batteries. Each type of battery core has its own strengths, but over time, Li-Po and Li-ion battery cores are currently used more. Below are some notable features of these types of backup charger battery cores.
Lithium polymer (Li-Po)
Li-Po battery cores require the most cost in the production process, the advantage of backup chargers using this type of battery core is that they have a longer product life, extend the battery life, good performance and are thin and light. In addition, Li-Po battery cores also allow users to charge the battery at any time, regardless of how much battery capacity is left inside without affecting the quality of the charger too much.
In fact, this is also a technology widely applied on most smartphones today. But Li-Po batteries are not eternal and still have a certain lifespan. According to statistics from experts, Lithium polymer battery cores can maintain almost unchanged quality for about 1,000 charges.
If you own a Li-Po power bank, note that it doesn’t need to be charged for a full eight hours the first few times, but don’t let it run out of juice or leave it plugged in overnight. Also, the battery will wear out faster if you use it while charging, which is true for all Li-Po devices including smartphones and power banks.
Lithium-ion (Li-ion)
If you look at old “brick” phones or early smartphones, you will see that most of these products are integrated with Lithium-ion batteries, also known as Li-ion. Until now, this battery core technology is still widely used in many electronic devices because it has many advantages such as reasonable price and long life. Products using this battery core will maintain quality for about 500 to 1,000 charge-discharge cycles.
The characteristics of this type of battery are that its durability and safety are greatly determined by the materials used to manufacture it. Therefore, you should buy Li-ion backup chargers from reputable brands such as to ensure the best quality. In addition, if you intentionally apply an input voltage that is too high, the quality of the battery will decrease rapidly.
Note when using a backup charger with a Li-ion core: try to charge it for eight hours for the first three uses, avoid letting the battery run out of power, and turn off the power immediately when the battery is 100% charged. In addition, because Lithium-ion batteries get hot easily when charging, you should place the backup charger in a well-ventilated area.
Core Cell Battery
The structure of the Cell core battery usually includes many small batteries combined with a structure similar to that of a small battery. Among the types of backup battery cores, the Cell core is often the least used today because of its much lower durability and the phenomenon of virtual batteries due to instability. The backup battery market from 2015 and earlier was very popular with product lines using Cell cores, but in recent years, only Li-ion and Li-Po batteries remain.
To evaluate the battery capacity of the device at its optimal level, you can rely on the test information published by the manufacturer. The actual battery capacity of the device is usually around 70% of the number provided by the manufacturer.
A simple example for you is that the company announced that the device has a usage time of 12, 13 hours after 1 full charge, but in reality it will have a usage time of about 9 hours.
