The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V. At this point, the charger reduces the charging current as required to hold the sensed voltage constant at 4.2V, resulting in a current waveform that is shaped like an exponential decay.
A charging cycle is completed when a battery goes from completely charged to completely discharged. Therefore, discharging a battery to 50% and then charging it back up to 100% would only be counted as 1/2 of a single battery cycle. Battery cycles are used as an estimate of what a battery's overall lifespan will be.
About 65% of the total charge is delivered to the battery during the current limit phase of charging. Assuming a 1c charging current, it follows that this portion of the charge cycle will take a maximum time of about 40 minutes. The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V.
Cycle life refers to how many complete charges and discharges a rechargeable battery can undergo before it will no longer hold a charge. A charging cycle is completed when a battery goes from completely charged to completely discharged.
With this charging strategy the charging current is injected into the battery in form of pulses, so that a rest period is provided for the ions to diffuse and neutralize. The charging rate, which depends on the average current, can be controlled by varying the width of the pulses.
Proper battery charging techniques can significantly improve battery performance and life cycles. Thus, several factors such as fast charging, good quality of charging current, and avoiding under and over charging are considered.
