Since 2021, due to the significant increase in the prices of raw materials such as lithium carbonate, the average price of lithium batteries has risen to a maximum of 1.2 yuan/Wh in 2022. Since 2023, with the decline in the prices of raw materials such as lithium carbonate, the average price of lith...

Due to the rapid replacement of lead-acid batteries with lithium-ion batteries, some people switch to lithium-ion electric vehicles after buying lead-acid batteries. However, at the same time, they cannot help but question whether the previous lead-acid battery charger can be used for lithium-ion ba...

Due to buying two lithium batteries when purchasing a camera, I have been reluctant to use one battery. Today, when I took it out to charge it, I found that the charger's light flickered twice and did not light up, making it impossible to charge. What should I do? Later, I searched online and fo...

When charging a battery, you should charge it according to the charging current recommended by the battery manufacturer. You can choose a charging current that is one-tenth of the battery capacity (which is called fast charging for the battery), or you can also choose a charging current that is one-...

Parallel connection: Several batteries, positive and positive, negative and negative, are connected side by side with the same voltage. As the capacity increases, the corresponding current also increases. Series connection: Several battery heads and tails are connected in series, that is, positive a...

"Virtual power" is an unprofessional term. It is a common name given by ordinary users to one of the characteristics of batteries. Every battery has such a physical characteristic: as long as there is electrical energy in the battery, the battery itself may try to maintain its nominal phys...

With the continuous development of the global economy, the energy crisis is gradually deepening, and environmental awareness is constantly increasing. As a new energy and environmentally friendly low-carbon power battery industry, lithium-ion batteries have developed rapidly. With their excellent pe...

1. Internal charging circuit malfunction, unable to charge normally.2. There is an internal malfunction in the 18650 lithium-ion battery.3. The battery electrode contact is dirty and the contact resistance is too high, causing a large voltage drop. When charging, it is considered that the host is fu...

Do not charge the battery for too long. If it exceeds the charging time, it will reduce the battery's service life. The most suitable working temperature for the battery is room temperature (10-25 degrees). Operating environments with high or low temperatures will reduce the battery's servic...

1) Whether the battery has been subjected to external short circuits, overdischarging, or reverse charging (reversing the positive and negative terminals of the battery or charger, which is equivalent to forced overdischarging during battery charging); Is the electrical circuit functioning properly;...
