I'm dealing with some power estimation spreadsheets that list battery
capacities and circuit current usages.  All these parameters are in
units of mAh (milliamp-hours).  Is there a standard symbol for mAh for
use in data sheets?  Also, what is the proper definition for mAh?

Examples of proper symbols often used in data sheets: "V" is the
symbol for volts, "I" is the symbol for current, "t" is the symbol for
a time period, etc.  Examples of proper definition: "electrical
potential" is the proper definition for volts, "current" is the proper
definition for amperes, "time" is the proper description of seconds,
etc.?  "Capactiy" seems like a good "proper name" from a battery's
point of view: the battery has a capacity of 1000mAh.  But it doesn't
make sense from a circuit's point of view: the circuit has a capacity
of 10mAh.
