Troubleshooting Lithium Batteries: What to Do When Your Battery Won’t Charge


Are you tired of your lithium battery dying when you need it the most? It’s frustrating, but don’t worry – we’ve got you covered. In this blog post, we’ll be discussing the common reasons why lithium batteries die and what to do when they won’t charge. We’ll also share some tips on how to prolong the life of your battery so that it lasts longer than usual. So sit back, relax, and get ready to troubleshoot your lithium battery like a pro!

Why Lithium Batteries Die

Lithium batteries are a popular choice for powering electronic devices due to their high energy density and long lifespan. However, even the best lithium batteries will eventually die, leaving your device powerless and unusable.

One of the main reasons why lithium batteries die is simply due to age and usage. Over time, the battery cells degrade and lose their ability to hold a charge. This is a natural process that cannot be avoided entirely.

Another reason why lithium batteries may fail is overcharging or undercharging. If you consistently overcharge your battery or let it drain completely before recharging, this can cause damage to the internal components of the battery cells.

Environmental factors such as extreme temperatures can also play a role in reducing the life expectancy of your lithium battery. Exposure to high heat or cold can cause irreversible damage to the chemical makeup of the battery cells, leading to premature failure.

In some cases, manufacturing defects or faulty designs may also contribute to early battery failure. It’s important to purchase quality lithium batteries from reputable manufacturers who have strict quality control standards in place.

By understanding these common causes of lithium battery failure, you can take steps to prolong the life of your device’s power source and troubleshoot any charging issues that arise in order to get back up and running quickly.

How to Revive a Dead Battery

Reviving a dead lithium battery can be a challenging task, but it is not impossible. Before you give up on your battery and decide to replace it, try these simple steps to bring it back to life.

Firstly, check the voltage of the battery using a voltmeter. A fully charged lithium-ion battery should read between 4.2V and 3.7V per cell. If the voltage is below this range, then proceed with caution as over-discharging can damage the cells.

Next, connect your dead battery to a charger that has been designed for lithium batteries. Be patient as charging may take longer than usual due to the low voltage of the battery.

If your charger does not seem to be working, try jump-starting your lithium-ion battery using another compatible power source such as an external power bank or laptop USB port.

In some cases, leaving your dead lithium-ion battery in a cool place for several hours before trying again can also help revive its charge capacity.

Remember that reviving a dead lithium-ion battery is not always successful and attempting any of these methods comes with risks such as damaging cells or even causing fire hazards if done improperly. Always exercise caution when dealing with damaged batteries and consider seeking professional assistance if necessary.

How to Prolong the Life of Your Lithium Battery

To prolong the life of your lithium battery, there are a few things you can do. First and foremost, avoid exposing it to extreme temperatures. High heat or cold can damage the battery’s cells and cause it to degrade faster.

Another thing you can do is avoid overcharging or completely discharging your battery. Most lithium batteries have built-in protection circuits that prevent overcharging or deep discharges, but it’s still best to keep an eye on how much charge your battery has left.

When storing your device for long periods of time, make sure to store it with a partial charge rather than fully charged or completely discharged. This will help preserve its longevity in the long run.

It’s also important to use the right charger for your device and not rely on cheap knockoff chargers that may damage the battery over time. Always use a charger that is designed specifically for your device.

If you’re not using your device for an extended period of time, consider removing the battery altogether and storing it separately in a cool dry place until you need it again. This will help prevent any degradation from occurring while not in use.


By following the tips in this article, you should be able to troubleshoot and revive your lithium battery if it won’t charge. Remember to check for physical damage, avoid overcharging or overheating, try charging at a slower rate, and consider using a battery desulfator.

However, prevention is always better than cure when it comes to batteries. To prolong the life of your lithium battery, make sure to store it properly when not in use and avoid completely draining it before recharging. Also, keep an eye on its temperature and don’t expose it to extreme heat or cold.

In summary, understanding why lithium batteries die and how to fix common issues can save you time and money in the long run. With proper care and maintenance, your lithium battery can power your devices efficiently for many cycles ahead.
