6 FAQs about [How to calculate the eight-year life of new energy batteries]
How is battery life calculated?
Generally, battery life is calculated based on the current rating in Milliampere (mA) and the capacity of the battery in Milliampere Hours (mAh). The battery life can be calculated from the input current rating of the battery and the load current of the circuit. Battery life will be high when the load current is low and vice versa.
How to prolong battery life based on number of cycles?
It is difficult question to answer, but it is important to go to the battery manufacturer specifications. Stop charging at 90% and start recharging at 30% will lengthen the battery life span. How do you calculate the battery degradation based on number of cycles?
What is battery life cycle?
