This battery has a low internal impedance and has nearly the same capacity at all tested loads.
















Because the voltage is lower at higher loads, the energy will be lower, even when the capacity is the same.









Conclusion

This battery is a lower capacity battery, but works well at higher discharge currents.
All in all a very good battery.
