Confused about battery rating specifications
Believe the specification.

All chemical batteries will have reduced capacity at higher discharge rates.


  I thought the amp-hour rating was high if you specify shorter periods of time. 


No, you can draw a higher current for a shorter time but the total energy the battery provides will be lower at higher discharge rates. There will be several reasons for this including the higher operating temperature at the electrodes due to higher current and the I2R internal heating losses due to the internal equivalent series resistance.
