What are the reasons why the battery is dead
First, overcharging: If the device is plugged into the power supply for a long time, especially overnight, it is likely to cause overcharging, which will harm the battery capacity and overall performance health.
Second, deep discharge: Let the battery discharge too much before charging, especially lithium-ion batteries, resulting in reduced capacity and life.
Third, high temperature attack: placing the battery in a high temperature environment, such as placing it in a hot car or near a heat source, will accelerate the chemical reaction inside the battery, resulting in rapid battery degradation.
Fourth, physical damage: accidentally dropping the device may cause physical damage to the battery, so that the internal short circuit or rupture, resulting in the battery can not be used.
Fifth, manufacturing defects: Generally speaking, some batteries have certain inherent defects in the manufacturing process, such as material impurities or structural defects, which may lead to premature battery failure.
The sixth, aging and wear: like the items used in ordinary times, the battery gradually degrades in the process of repeated charging. As the battery ages, the capacity will also continue to decrease, resulting in shortened service life and eventually failure.
Improper storage: Storing the battery in an inappropriate environment of extreme temperature or high humidity will accelerate the degradation of the battery, resulting in premature battery failure.
Software failure: In some special cases, software problems inside the device may lead to abnormal battery consumption and charging problems, which, if not solved, will lead to premature battery failure.
How to revive dead batteries?
Fixing a dead battery is a useful skill that can save you time and money. Here are some ways to help:
Charge the battery slowly
The easiest way to restore a dead battery is to charge it slowly. Use a low-current appliance or professional battery recovery device to start charging with a very low current (usually 1/10 of the standard current). Then slowly increase the current until the current voltage reaches the normal level.
This charging process takes some time, so we have to be patient. Once the battery has reached a sufficient charge, it will start working again.
Parallel charging
Take a battery with good performance and the same model, and connect it in parallel with the depleted battery. It continues to use a low-current charger to charge both batteries at the same time. It should be noted that this method has certain risks and needs to be operated with caution.
Jumper start battery
Jump-start is the standard way to restore a car’s battery charge. This is the use of jumper cables to connect the dead battery to the normal operation of the vehicle battery. Let the normal running vehicle run for a few minutes, then try to start the car with a dead battery, and if successful, let it run to recharge.
Precharge
For completely dead batteries, some smart chargers have a pre-charge function. This method can safely inject a small amount of current into the battery, which activates the protective circuit.
Use a battery repair device
Battery Repairers are devices designed specifically to restore the performance of depleted or low charge batteries. They help break down sulphate, a common cause of battery failure, thereby improving the overall health of the battery.
Preheating cell
If the battery temperature is low, heating the battery to room temperature can improve its performance. At the same time, too much heat should be avoided, otherwise it may further damage the battery.
How to repair a lithium-ion battery that cannot be recharged?
If you encounter a lithium-ion battery that cannot be recharged, consider trying the following:
Check the charger and connection
First, check the charger for any signs of damage, such as frayed wires or bent connectors, to make sure the charger is functioning properly. Likewise, check the charging ports and cables on the device for damage or dirt obstacles. Ports can be cleaned with compressed air or a soft brush to help with proper connection and restore charging function.
Frozen battery method (Use with caution)
This method requires placing the battery in a plastic sealable bag and then freezing it in the refrigerator for 8-12 hours. Then remove the battery and bring it back to room temperature, then try charging it.
A frozen battery can temporarily restore its ability to hold power by stabilizing internal chemicals. However, it should be noted that this method may have certain risks and is not suitable for all types of batteries.
Perform a hard reset
Hard reset can solve the problem of lithium-ion battery charging, the specific operation method is: first turn off the device, if you can remove the battery, then press and hold the power button for 15-20 seconds. Then reinsert the battery and try to charge the device again.
Reset Battery Management System (BMS)
Some devices have a built-in battery management system (BMS) that regulates charge and discharge. Sometimes, resetting the BMS can solve the charging problem. This is done by fully discharging the battery and then continuously charging it to its total capacity.
Voltage activation. Using an adjustable power supply, a voltage slightly higher than the nominal voltage of the battery is applied. For a few seconds, it may be possible to reactivate the battery’s protective circuit.
Professional restoration service
If many of the methods used are not working, then consider seeking a professional battery repair service. They may have specialized equipment and techniques to diagnose and fix problems.
Peplace battery
If all else fails, the lithium-ion battery itself may be the source of the problem. In this case, it is recommended to contact the device manufacturer or a professional technician to replace the battery. Be sure to buy genuine batteries that are compatible with your device, as counterfeit or incompatible batteries can pose a safety risk.
How long can a lithium-ion battery last without a charge?
The use time of lithium-ion battery without charging depends on factors such as battery capacity, self-discharge rate, device power consumption, and usage mode.
Battery capacity
The initial capacity of the battery also plays a role. Batteries with higher capacity tend to hold their charge longer than batteries with lower capacity. However, it is important to note that regardless of the battery capacity, the self-discharge rate is still a factor.
Power consumption
If the device is in a state of high power consumption, such as frequent use of mobile phones for various operations, running energy-intensive applications, lithium-ion battery may only last a few hours to about a day.
Lithium-ion battery naturally lose charge over time even when not in use. The self-discharge rate varies by battery model, but is usually lower. On average, lithium-ion batteries retain about 80 percent of their charge after a month of non-use.
Pattern of utilization
If the device is in standby state and the power consumption is very low, it may last for days or even weeks. For some devices with only a simple clock function, lithium-ion batteries may last several months.
Important note
Safety first
Be very careful when handling batteries, especially when trying unconventional methods. If there is any physical damage, expansion or leakage of the battery, avoid attempting to repair it and dispose of it immediately and safely.
Prevent excessive discharge
Charge the battery regularly to avoid deep discharge caused by prolonged non-use. Try to keep the battery charge between 20% and 80%. Try to complete the charge and discharge cycle, rather than frequent short-time charging.
Proper storage
When not in use for a long time, charge the battery to about 50% power for storage. Keep in a cool, dry environment and avoid extreme temperatures.
Original accessories are used
Use original chargers and cables whenever possible to ensure compatibility and safety.
Regular maintenance
Check the battery health regularly to find problems in time. If your device supports battery health check, use it regularly.
Professional help
If you are not sure how to handle this, or feel there is a certain risk, please seek professional help.
For recycling
If the battery cannot be repaired, please ensure that it is recycled through the appropriate channels and not discarded at will.
In general, there are many ways to try to recover and repair lithium batteries, but safety is always the first priority. Proper use and maintenance can greatly extend the life of the battery and reduce the possibility of problems.
