Lithium-Ion State of Charge (SoC) measurement. There are several ways to get Lithium-Ion State of Charge measurement or Depth of Discharge (DoD) for a lithium battery. Some methods are quite complicated to implement and require complex equipment (impedance spectroscopy or hydrometer gauge for lead acid batteries).
It is usually expressed in milliamp-hours (mAh) or ampere-hours (Ah). By integrating the lithium battery charge curve and discharge curve, the actual capacity of the lithium battery can be calculated. At the same time, multiple charge and discharge cycle tests can also be performed to observe the attenuation of capacity.

Charge rate or charge speed Charge rate or speed is how long it takes a lithium-ion battery to be recharged after use. This is often measured in time and capacity range (i.e. 20 min to charge from 10-80% capacity) or measured in C-rate, same as discharge (i.e. a 6C capable battery would charge in roughly 10 minutes).
Understanding the capacity of a lithium battery is vital for several reasons: Estimating Battery Life: Knowing the capacity helps you predict how long the battery will last on a single charge. This is crucial for planning usage, especially for devices you rely on heavily.
Lithium ion batteries when sold should show a 60% charge if they have been properly stored. When storing lithium-ion batteries yourself you should discharge to 60% and keep in a freezer. This is for long term storage (read: Months), not for a couple days between uses. Aug 25, 2011 at 7:59 Assessing full charge is the easy part.
