How to maintain batteries

Time:2022-07-27

Many friends ask, batteries are useful every day, but how to maintain the battery, this aspect of knowledge is very scarce, so today's mini-series here to explain how to maintain the battery, so that it can be used efficiently.

1. Protection chip, lithium battery on the charge and discharge of the current and voltage access has very strict requirements, in order to protect the battery from damage caused by external electrical environment, the battery itself will be set up to manage the battery status chip. The chip also has the function of recording battery capacity and correcting battery capacity. Now, even the fake cell phone batteries won't save this key protection chip, otherwise the fake cell phone batteries won't last long.


2, avoid abnormal battery or charging line, detect abnormal circuit and protect mobile phone.


3, over charging: for lithium batteries. Under normal circumstances, lithium batteries will be charged to a certain voltage (that is, full) will be cut off by the higher circuit charging current, but due to some devices built-in overcharge overdischarge protection circuit voltage and current parameters are different (such as mobile phone battery seat charge), resulting in although already full, but not stopped charging phenomenon. Overcharging can also cause damage to battery performance.


4. Activated lithium batteries (more than three months) do not use for a long time, will produce electrode materials passivation, battery performance decline, can be used three times fully charged, complete discharge to remove purification, play the highest performance of the battery.

5, the memory effect of Ni MH rechargeable battery on the common phenomenon. Specifically, if you start using batteries when you are not charged for a long time, the battery's power will be significantly reduced, even if you want to fill it up later. So the important way to maintain the Ni-MH batteries is that the electricity must be used up before it can be charged, and when it is full, it is allowed to be put into use. The memory effect of commonly used lithium batteries is negligible.


6, lithium battery. Full discharge refers to the process of adjusting the power consumption of smart devices, such as mobile phones, to a minimum power state until the phone shuts down automatically. Full charge is the process of connecting a fully discharged smart device, such as a mobile phone, to a charger until it is prompted to "fill up".


7, excessive discharge is for lithium batteries. After full discharge, a small amount of electricity will remain in the lithium battery, but this part of electricity is very important for the activity and life of the lithium battery. Overdischarge: After full discharge, if you continue to use other methods, such as: forcibly re-open the phone, the battery connected to the small bulb to consume residual electricity, which is called overdischarge, will cause irreversible damage to the lithium battery.
