Power Bank Warning Signs: Lithium-ion batteries are used in most power banks. This battery does not deteriorate immediately and gives many warning signs first. These signs indicate that the battery is about to get damaged and you will have to replace the power bank. Generally a power bank getting damaged gives 6 types of signs. If any of these signs are visible on your power bank, it indicates that the battery is getting damaged and you should consider replacing it.
Keep an eye on these signs
Swelling- If the power bank is swollen then this is the most serious warning. When the liquid electrolyte in the battery installed in the power bank starts breaking down, flammable gases are generated. The power bank is completely packed, due to which the gas does not get any space to escape. Due to increase in pressure the cover of the power bank starts swelling. In such a situation, stop using it. Do not try to take out the gas by puncturing the pouch. Doing this can be dangerous.
overheating- It is normal for the power bank to heat up a bit during use, but if it starts heating up even without use or starts overheating during use, then it should be considered an alarm bell. Usually such a problem occurs when there is a fault in the protection circuit. If this problem starts appearing in your power bank then you should stop using it.
Burning Smell- While using the power bank, if there is a chemical or burning smell coming from it, then it indicates that everything is not right. Such odor occurs due to damage to the internal insulation or short circuit. Therefore, do not ignore it and stop charging or discharging the power bank.
Visible damage- If the power bank is physically damaged then it can also be dangerous. If you see cracks or dents etc. in it then use it carefully. Dents on the top of the battery can be more dangerous than on the corners. If it starts overheating after getting damaged, then stop using it.
Change in charging behavior- If the battery that appears to be full gets discharged suddenly or the power bank keeps turning on and off repeatedly, then it also shows that it is time to replace it.
