These simple guidelines are a summary of what we have discussed in details. Simple Rules for Charging Li-ion Batteries Take time to read these simple guidelines or rules in charging a Li-ion battery. To sum up, the charging process for Li-ion cells. When you turn-off the charger, it automatically drops the voltage and reduces the stress on the battery. It may compromise safety when you fail to cut off the charging process. Doing these may cause a metallic lithium plating. Once it reaches full charge, you must cut it off immediately. The state of charge (SOC) for step 1 reaches only 85% charge and it is the most recommended level for Li-ion charging.ĭo not attempt to overcharge a lithium-ion battery. It is not advisable for this kind of battery to reach stage 2 or the saturation stage. Choosing a low voltage rate is highly recommended for a Li-ion battery. The high voltage or high flow of current causes too much stress on the batteries. It is not advisable to fully charge this type of cell. Unlike lead-acid batteries where it needs a 100% complete charging, a Li-ion battery does not need it. You may also consider it as a full charge when the current levels are off and cannot go down any further.ģ. Li-ion battery reaches full charge when it reaches the voltage threshold when the current reading registers at 3% of the current rate. If the battery temperature rises more than 10 degrees C, you must stop charging the battery.
Some Li-ion cells may reach a reading temperature of about 5 degrees C when it becomes fully charged. 08 C or even less to extend the life of the battery. The complete charging time will take about 2 to 3 hours.īattery manufacturers usually recommend charging it at. If you are using a trickle charge, most chargers uses topping when the level of current drops.
You will be able to prolong the usage of these battery type.Ī Li-ion battery reaches full charge when the current drops to a set level. Knowing these simple tips for properly charging your lithium-ion batteries will take a long way. 4 Tips On How To Charge Your Lithium-Ion Battery Properly Lithium or not, the care and maintenance must be the same. Therefore, it is equally important to care for your lithium-ion batteries the same way you care for a regular car battery.
