For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.

maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
