Questions about this item

How long will the 1.25 Ah capacity last during a typical shoot?

The 1.25 Ah rating delivers 9.25 Wh at 7.4 V, giving roughly the same run-time as the original Pentax D-LI90 in compatible bodies such as the K-1 or 645Z.

Does the 7.4 V output match the Pentax D-LI90 specification exactly?

Yes, 7.4 V is the nominal voltage of the original D-LI90, so the camera's power management sees no difference.

Will the 40.00 x 57.00 x 21.00 mm dimensions fit the K-3 II battery compartment?

Those dimensions match the D-LI90 form factor, so the cell seats and latches correctly in every listed Pentax model including the K-3 II.
