Battery cells are permanently degraded when discharged at a high current. Which is why manufacturers specify a maximum current rating. Its value is not a hard limit: degradation occurs even if the current is less than the rating, just not as fast.
With some batteries the current should be artificially limited to protect the battery from self-destruction. It may be able to produce a high current for a short time and then chemical products build up that limit the current ("polarization"). The electrolyte and connections will have some resistance and that limits the current.
If so, the battery voltage is half of the nominal (e.g., 4.5 V) and the power wasted in heat is equal to the power doing work in the load (the efficiency is 50 %). This is called the "Maximum Power Point". Additionally, there are physical effect that limit the current even further, such as the mobility of the ions inside the battery cells.
The discharge current limit (sometimes referred to as DCL for short, or load current limit) represents the maximum amount of current (measured in amps) that can be pulled or drawn from the battery pack without damaging or exceeding system ratings.
