A mobile phone battery labelled 
capacity is fully charged initially. What percentage of capacity remains after it has delivered a current of 
for 
hours?
Background. (C-rate)
C-rate (in 
) is defined the charging or discharging current (in 
) divided by the charge capacity (in 
).
Background. (Capacity's)
Capacity 
rated in ampere hours:
is equivalent to a measure of charge as in coulometry; whereas in watt hours
a measure of energy as in voltammetry.
Background. (state of charge/depth of discharge)
Background. (full/nominal/cutoff voltage)
Limited in my knowledge, may I write
