Can you reboot a lithium battery?
Key Takeaways
- Lithium-ion batteries can be rebooted to potentially extend their lifespan.
- Methods to reboot a lithium battery include slow recharging with a USB charger, applying a brief, high-current discharging step, resetting the battery, using a charger with a “boost” or wake-up feature, and performing a deep discharge.
- Not all lithium-ion batteries can be successfully rebooted, and there may be risks associated with attempting to do so.
Yes, it is possible to reboot a lithium battery. Over time, lithium-ion batteries can degrade and lose their ability to hold a charge effectively. However, there are several methods that can be used to revive these batteries and potentially extend their lifespan. In this article, we will explore different techniques that can be employed to reboot a lithium battery, as well as the research and advice provided by experts in the field.
Method 1: Slowly recharge with a USB charger
According to an article from ZDNet, a dead lithium-ion battery can be revived by using a basic USB charger. The process involves allowing the battery to draw minuscule amounts of current until it reaches a point where it can take a proper charge. This gradual recharging method reduces the risk of explosions or fires that can occur when attempting to charge a severely depleted battery too quickly.
Method 2: Applying a brief, high-current discharging step
Researchers at SLAC National Accelerator Laboratory and Stanford University have made an interesting discovery that could revitalize rechargeable lithium batteries. As explained in an article from the SLAC website, they found that applying a brief, high-current discharging step after charging the battery could partially reverse the degradation process. This step helps reconnect isolated islands of inactive lithium with the electrodes, resulting in an increase in the battery’s lifetime by nearly 30%.
Method 3: Resetting the battery
Resetting a lithium-ion battery is another approach that can potentially revive it. Techwalla provides a step-by-step guide on how to reset a lithium-ion battery. The process involves using the device until the battery is completely discharged and then connecting it to a power source to fully charge it. If the device has an external charger, the battery can be removed and placed in the charger for charging. This method aims to recalibrate the battery and restore its functionality.
Method 4: Using a charger with a “boost” or wake-up feature
Battery University explains that a charger with a “boost” or wake-up feature can be used to reset a lithium-ion battery. This feature applies a small charge current to activate the battery’s protection circuit. If the correct cell voltage is reached, the charger will initiate a normal charge. However, it’s important to note that boosting lithium-based batteries that have dwelled below 1.5V/cell for a week or longer can potentially cause damage.
Method 5: Performing a deep discharge
Another way to potentially fix a lithium-ion battery that won’t charge is by performing a deep discharge. Battery Realm suggests that a deep discharge or resetting the battery can help revive it. This involves fully discharging the battery and then attempting to recharge it. While this method may work in some cases, it is important to exercise caution and follow manufacturer guidelines to avoid any potential risks.
Overall, there are multiple approaches that can be taken to reboot a lithium-ion battery. From slow recharging with a USB charger to applying a brief, high-current discharging step, and resetting the battery through various methods, there are options to potentially revive a dead or degraded lithium-ion battery. However, it is important to note that not all batteries can be successfully rebooted, and there may be risks associated with attempting to do so.

FAQs:
Q: What are the advantages of lithium batteries over other types?
Lithium batteries have several advantages over other types. They offer higher energy density, meaning they can store more power in a smaller size. They also have a longer lifespan and can maintain a higher voltage throughout their discharge cycle. Additionally, lithium batteries have a lower self-discharge rate, allowing them to hold their charge for longer periods of time.
Q: How can I potentially “reboot” a lithium battery?
There are a few methods that can potentially “reboot” a lithium battery. One option is to fully discharge and then recharge the battery. Another method is to use a battery management system (BMS) to balance the cells and reset the battery. Lastly, applying a controlled voltage reset can also help in rebooting a lithium battery. However, it is important to note that these methods may not always work and there are risks and limitations associated with rebooting lithium batteries.
Q: What are the recommended charging practices for lithium batteries?
To maintain and extend the lifespan of lithium batteries, it is recommended to follow these charging practices: use the appropriate charger for your battery, avoid overcharging by disconnecting the battery once fully charged, and avoid deep discharging by recharging the battery before it reaches a critically low level. It is also important to monitor the charging process and avoid exposing the battery to extreme temperatures.
Q: How should I store lithium batteries properly?
Proper storage is crucial for maintaining the lifespan of lithium batteries. It is recommended to store them in a cool, dry place away from direct sunlight. Ideally, the temperature should be between 15-25 degrees Celsius (59-77 degrees Fahrenheit). Additionally, it is important to store lithium batteries at a partial charge, around 40-60% capacity, to prevent them from fully discharging or overcharging during long-term storage.
Q: Why is it important to understand lithium battery care?
Understanding lithium battery care is important because it directly affects their lifespan and performance. By following best practices for storage, charging, and maintenance, you can maximize the lifespan of your lithium batteries and ensure they consistently deliver optimal power. This knowledge also helps in preventing potential risks such as overcharging, deep discharging, or damaging the battery, ultimately saving you time, money, and the hassle of frequently replacing batteries.
