How can i calculate the number of cycles in lithium battery?
Answers
Answer:
Calculating the life-cycle of a battery based only on its allowable charge rate and discharge rate is unrealistic. The life-cycle of a battery depends not only on its charge levels, but its chemistry, environmental factors (e.g. temperature, ageing, etc), whether the battery is over-charged or under-charged, and how it is loaded (e.g. are there regular high-current pulses or a steady load). Then, of course, there are various failure-modes of a battery. These include design faults, manufacturing faults, abuse of the battery, uncontrolled operating conditions, breakdown of electrolyte, and so on. The typical method for estimating the life-cycle of a battery is statistical and based on historical data. For example, a battery of a particular chemistry (e.g. lead-acid, Lithium) will on average fail according to a particular statistical distribution. Battery manufacturers will often have an mean-time-before-failure (MTBF) metric that helps to estimate the life-time of the battery.

Answer:
Multiply these two numbers to get the watt-hour rating (Ah × V = Wh). Note: If the capacity of your battery is expressed in milliampere hours (mAh)—like in the image above— you will need to divide by 1,000 to calculate the ampere-hours (Ah) before multiplying.
