How much current does a coin cell battery have?
The coin cell batteries are limited in discharge current to 390 A, however we tried to pull 3A and 0.3A from them. As a result there was an initial voltage spike as the batteries were attached to the circuit followed by an immediate drop in voltage and a slow decay of the remaining voltage that the batteries provided to the circuit.

While excessive parasitic battery drain is considered a problem, most vehicles experience a "normal" amount of battery drain. …
batteries
Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.

Battery Internal Resistance
Battery internal resistance is the opposition to the flow of current within the battery. For many years, batteries were often assumed to be ideal voltage sources. In simple terms, this means that the battery would always provide a constant voltage regardless of the load connected to it. However, in reality, no battery can act as a perfect voltage source due to its …
