Keeping a close eye on these charging and discharging patterns can help you identify any potential issues with the battery.
Physical signs of battery degradation are also worth considering. Although lithium-ion batteries don’t exhibit as many noticeable physical changes as other battery types, there are still some signs you can look out for. For instance, if the battery becomes excessively hot during use or charging, it may indicate a problem with the battery’s internal components. Similarly, if you notice any bulging or swelling in the battery, it could be a sign of a damaged or defective cell. These physical signs should not be ignored, as they can indicate potential safety hazards.
How Long Do Lithium Ion Batteries Usually Last?
When it comes to lithium-ion batteries, one common question that many people have is: How long do they actually last?
