So, if it has been a problem for you before, we suggest following our guide. In short, we’ll show you how to fix a battery that won’t charge in different ways and also give some tips on how to prevent this from happening in the future.

Common Issues of Lithium-ion Battery That Won’t Charge

While Lithium-ion isn’t charging seems to be a big issue itself, there might be some underlying problems that lead to that situation. Here are some common issues that might be responsible for why your Li-ion battery won’t charge. 

  • BMS Failure

If the charging indicator pops up on the screen, the power is on, and the device isn’t unresponsive, then it’s likely to be a problem with the battery management system. The batteries, because they aren’t balanced, might not be able to provide the appropriate voltage or current.

  • Internal Damage

Batteries left unused over time will gradually run flat and chemicals may accumulate in this section, leading to internal damage. 

Many devices are powered by starter batteries, such as handheld vacuums; including these, sulfate crystals construct on the plate and may sometimes block the unit. 

  • Abnormal Discharge Rate

No battery loves to stay in “flat” condition, but when a Li-ion discharges abnormally, it frequently stays in that condition, and you may not be able to monitor this all the time. Since the battery remains in flat condition too often, it may gradually turn into charging issues.

How To Fix A Lithium-ion Battery That Won’t Charge

If you’re like most people, you probably have Li-ion batteries around. You use them to power your devices, or even just hold on to your daily strata workouts. But if one of your Li-ion batteries isn’t charging, it can be quite frustrating. 

Here’s how to fix a Lithium-ion battery that won’t charge.

  1. Fully Recharge The Battery

If you’ve drained your battery to within an inch of its life, you can return it to health by performing a complete recharge. Follow the steps mentioned below:

  • For this process to work, the charger will be required to get extremely low on power, so you should continue connecting it until it powers down. 
  • When the charger doesn’t need much power, ensure that you connect to a power source, so it can power up. Allow the battery to charge for at least 48 hours. 
  • The base voltage of the lithium battery must not be below 2 V. When the battery is exposed to over-discharge, its surface structure will be broken down, resulting in the battery operating slowly. 
  • In instances that use universal chargers instead of chargers that support AGM batteries, excessive self-discharge can occur. 
  • Using a charger that is being constantly controlled to prevent overcharging of an overvoltage and discharging the battery instead can resolve the issue.

Imbalance in the current flow may be the second note as to why a battery is not performing. Uneven charge distribution within the cell may be attributable to contact resistance or charge detection. 

High voltage gets wrung out of the short-term cable if the wattage difference isn’t huge, but it becomes significant if the cable remains in one position for hours. Automatic error correction is useful after a power issue like this one, which has nothing to do with product performance. 

If the battery you’re trying to fix is linked to something that you use frequently, you may want to work with it over the weekend or rent a substitute that you can either use as a temporary fix or use a few days after you finish the work.

  1. Jump Start The Battery

By definition, getting things going requires the quick application of a bit of force. In the information age, even money enthusiasts have needed to jump-start a vehicle. 

Though you may need to perform this procedure several times, restoring a battery-powered gadget or something similar is basically the same as running a gas or electric battery. 

However, putting together a wiring project is never risk-free, so be careful and take your time to understand what to do first. Remove the battery from the device, and also take notice of the positive (+) and negative (-) inputs carefully. 

Now you’ll have to remove the A connector from the smaller end of a USB cord to avoid uncertain short. Uncover the B connector to expose red cables whose positive and negative terminals you have to learn about the USB cord.

Then connect the battery to your pier or router, then link the uncovered wires into the appropriate cords on the battery by reaching them with a soldering iron. At this point, the battery should be revived and take in electrical power.

  1. Repair The Battery As Soon As You Can

You may think about repairing your Li-ion battery as well. In this case, a soldering iron and a little trust in yourself are all you’ll need to fulfill the repair process. 

However, you should bear in mind that working with batteries and electronic equipment has some inherent risk, so you can approach the task only with extreme caution.

  1. Replace The Battery Without Hesitation

Frankly speaking, getting a new battery will enable you to accomplish your end goals safely and ensure that your device won’t malfunction. And, of course, it’s the safest way. 

The decreased price point of lithium-ion batteries over the last few years has stemmed from the ever. We’re used to our mobile devices and portable technology, so a store will try to offer you a brand-new battery just to keep your system operating correctly.

Maintenance Tips for A Longer Battery Life

Maintenance Tips for A Longer Battery Life

Similar to any electrical or mechanical component, lithium-ion batteries need regular maintenance to run more efficiently and ensure a longer lifespan. Here are some crucial maintenance tips you should follow to get the most out of your Li-ion battery. 

  • Stick to the recommendations from the manufacturer on how to handle and use lithium-ion batteries. Extreme temperature variation can damage most components, including fire and explosion, in lithium-ion batteries. If your laptop or cell phone’s surface starts to heat while charging, unplug it. 
  • Ensure that the battery or battery-type device fully charges and discharges in a cool location at a bare minimum or not at all. Fast transitions between low and high temperatures can stress and endanger batteries. Consider using a partial charge that restores the battery to 80% rather than 100%.
  • Fast chargers are convenient, but they are also detrimental to batteries. Powering down improperly, excessively hastening discharge rates, or placing the gadget in small light without dimming will damage a lithium-ion battery. 
  • For smartphones and laptop computers, lowering screen brightness, turning off location services, and stopping excessive application use can all help prolong the battery’s lifespan.
  • Street chargers without protective features may be inexpensive, but you may be placing your device at substantial risk. If you do not acquire an original charger, you should purchase a branded, high-quality charger. 
  • Saving a couple of dollars when you purchase a charger may seem like a smart idea in the short term, but the four or five times the battery dies whenever you will need to charge it throughout the device’s lifespan will cost you dearly more.


  • How do you revive a lithium battery that won’t charge?

At first, you have to store the lithium-ion battery inside a closed plastic bag. Then place it in a freezer for a whole day. Make sure the inside of the bag is completely free from moisture to avoid damage. As you lift the bag out of the freezer, leave it there for an hour or two to warm it up to room temperature.

  • What should I do when lithium battery won’t charge?

To seize the negative electric charge accumulated in the lithium battery, the specific charger can recharge it when it is discharged. It is possible to prevent adding to the lithium battery for a comparatively long time by utilizing the charger under a low-voltage method for long charging.

  • How do you recharge a dead lithium battery?

Insert a bigger pin in the USB cable into a power source like a computer or power bank. Leave the connection setup for at least one minute while you monitor it, looking for any adverse indications. Gall the battery into the lithium-ion battery charger and bill it completely.

  • What reason might be responsible for an Onepwir lithium-ion battery not charging?

When it remains plugged into a device but will not charge, the battery itself may be to blame. There could be a couple of reasons for this, so the first thing to check may be the battery. The next item to check is the charger if you’re confident that the battery is in proper working order. Ensure that the charger is plugged in and operating correctly.
