Lithium batteries are becoming more and more popular due to their high energy density and longer life compared to other types of batteries. However, when it comes to charging problems, most users may don’t know what to do.

In this article, we will explore the common reasons that lithium batteries cannot be charged, the factors that affect charging and how to self-check the status of lithium batteries, hoping to help users have a deeper understanding of lithium batteries and the way to use.

Why are my Lithium Batteries Not Charging?

There may be a variety of reasons why a lithium battery cannot be charged.

1. 1. Battery aging: With the growth of using time, the performance of lithium batteries will gradually decline, resulting in lower charging efficiency or even no charging.
2. 2. Charger failure: Damage to the internal circuit of the charger or failure of the power module may result in the inability to provide normal charging voltage and current to the battery.
3. 3. Battery Management System (BMS) failure: The BMS is responsible for monitoring the battery status. lf the BMS fails, the battery may fail to enter the charging state or an exception may occur during the charging process.
4. 4. Battery protection mechanism start: Lithium battery in overcharge and other abnormal circumstances, the protection mechanism will start to prohibit the battery to continue to charge to avoid damage.
5. 5. Run out of battery power: lf the battery is fully discharged, it will need to be charged for some time (usually at least 1 hour) before the charging ability is restored.

What are the factors that affect lithium battery charging?

After knowing some reasons about lithium batteries cannot be charged, maybe some of you want to know what are the factors can influence the lithium battery charging, and the following are some of the main factors:

1. Battery status: The current state of charge (SOC) of the battery affects the speed and efficiency of charging. When the battery is close to full charge, the charging speed will naturally slow down.
3. Charger specifications: The output voltage and current of the charger have a direct effect on the charging speed. Using a charger that does not match the battery specifications can result in inefficient charging or damage to the battery.
5. Battery aging: With the increase of use time, the performance of lithium batteries will gradually decline, including charging speed and capacity.
7. Battery Management System (BMS): BMS is responsible for monitoring and controlling the charging process of the battery to ensure safety and efficiency. The algorithm and function of BMS have a direct impact on the charging process.

Except for these reasons, even the charging environment temperature, external load, charging methods etc., will affect the charging situation of the battery and the health of the battery. Finally, understanding these factors can help optimize the charging process of lithium batteries, extend battery life, and ensure safe use.

Watch until here, maybe some of your guys will say: if my lithium battery has some problems, how to jumpstart a dead lithium-ion battery? In here, the author provides some methods for you to choose.

Firstly, to check the battery and charger. Make sure there is no obvious damage or breakage of the battery and that the charger is working properly.

Secondly, Check whether the cell is damaged or voltage imbalance, if there is a problem may need to replace the cell or voltage balance.

Thirdly, some batteries require a specific activation strategy to be recharged, which may involve multiple charge and discharge cycles.

If the above methods can not solve the problem, it is recommended to contact professional maintenance personnel for inspection and repair. LeapPower has professional experts and more than 15 years manufacturing experience, which provide 5 years warranty with lifepo4 batteries. If you have any questions contact us, we will assist you.

5 tips to check whether the lithium battery is damaged or not.

 At the final part, the author will try to provide five tips to help you to check whether your lithium battery is damaged or not. And after knowing that, you can better understand the status of your battery, so that have a better use and maintain it,which can help you to save more electrity bills.

To check whether the lithium battery is damaged, you can make a preliminary judgment by the following methods:

1. 1. Appearance inspection:

Check whether the battery cover is expanded, deformed, or damaged. And then, you also need to check if there are any signs of cracking, corrosion, or leakage on the battery surface.

2. 2. Voltage measurement:

Use a multimeter to measure the battery voltage. If the battery voltage is much lower than the nominal voltage (for example, a fully charged 18650 battery is usually around 4.2V), it may indicate that the battery has been damaged or has run out of power.

3. 3. Charging test:

Try to charge the battery and see if it can be charged normally. If the battery does not charge properly or dies soon after charging, there may be a problem.

4. 4. Battery parameter comparison:

Compare the actual capacity of the battery with the nominal capacity. If the actual capacity of the battery is much lower than the nominal capacity, it may indicate a deterioration in battery performance.

4. 5. Temperature test:

An abnormal increase in battery temperature during charging or discharging can be a sign of a chemical reaction or short circuit occurring inside the battery.

Conclusion

Having a lithium battery fail to charge can be annoying, but by understanding the common causes and regularly checking for lithium battery health issues on a daily basis, you can solve many problems. In addition, following practices such as errors to avoid when charging, using compatible chargers, proper storage, and keeping devices updated will help prevent future charging problems.

The most important point! Remember, if in daily life, your lithium battery has a fault or after checking the problem, find yourself unable to solve, please seek professional help in time to ensure the safety of you and the battery to maintain its best performance.
