Charge that a battery can deliver depends on the discharge current (discharge time). If discharge current grows (discharge time decreases), the battery capacity decreases.
This dependence is an individual property of a specific battery. The dependence between relative battery capacity and discharge time for LCL-12V33AP battery is given in the table below.
Discharge time, hours Relative capacity,
0,1 37%
0,3 48
Qulon-12ns always shows capacity for 20-hour discharge time. If you discharge your battery during smaller time, the capacity will reduce.
