You need to know the current and the time to calculate the lithium-ion battery capacity. The current, usually measured in amperes (A) or milliamperes (mA), is the amount of electric charge that flows through the battery per unit of time. The time, usually measured in hours (h) or fractions of an hour, is the charge or discharge cycle duration.
Lithium-ion cells can be manufactured to optimize energy or power density. Handheld electronics mostly use lithium polymer batteries (with a polymer gel as an electrolyte), a lithium cobalt oxide (LiCoO 2 or NMC) may offer longer life and a higher discharge rate.
Lithium ion battery capacity is the utmost quantity of energy the battery can store and discharge as an electric current under specific conditions. The lithium ion battery capacity is usually expressed or measured in ampere-hours (Ah) or milliampere-hours (mAh).
Like all batteries the Li-ion battery also has a voltage and capacity rating. The nominal voltage rating for all lithium cells will be 3.6V, so you need higher voltage specification you have to combine two or more cells in series to attain it. By default all the lithium ion cells will have a nominal voltage of only ~3.6V.

Maximum discharge current : 1C. That means that it is rated to provide 250mA of current. As always, voltage can be raised by putting cells in series (but watch out for balancing issues), and current can be raised by putting cells in parallel. If both must be raised then a full array of cells must be used.
