What determines the charge rate us how fast a battery will accept current, without overheating or degrading. Kind if like filling a water tank. You can use a bucket or a firehose. Will the tank hold up to the force of the firehose? You can empty the tank by a small valve or dump it out all at once. The same analogy fits batteries. The discharge rate is basically determined by the resistance of the load put across it. Anyone who has left their headlights on overnight knows about this. A dome light will not give you a dead battery in the morning. There are others internal conditions in the battery that come into play, but this is the basics of the charge-discharge rate comparison.
