Kastar FNP120 Replacement Battery

The Kastar FNP120 is a lithium-ion replacement cell rated at 3.7 V and 2300 mAh, delivering 8.51 Wh of energy. It fits a wide range of compact cameras from Pentax, Fujifilm, Ricoh, Toshiba, Contax, Minolta and Ordro that originally used the D-LI7, NP-120, DB-43 or BP-1500S packs. Photographers who need a fresh power source for these legacy models can install it directly without modification.

Capacity and Headroom

At 2300 mAh the battery provides extended shooting time compared with lower-capacity alternatives, letting you capture more frames per charge. The integrated protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating, so the cell remains stable during long sessions. It will not suit users whose cameras demand higher voltage or proprietary communication protocols beyond the standard lithium-ion interface.

Practical Limits of the Li-Ion Standard

The 3.7 V nominal voltage and 8.51 Wh rating define the energy ceiling for any device designed around this form factor. Charging must follow standard lithium-ion CC/CV profiles; the pack cannot be fast-charged beyond the limits of the original charger. Cameras that require firmware authentication or higher discharge rates will not operate correctly with this replacement.

Questions about this item

Will the 3.7 V Kastar FNP120 fit and charge in my older Pentax Optio 550 that originally used a D-LI7 battery?

Yes, the FNP120 is listed as a direct replacement for the Pentax D-LI7 and is compatible with the Optio 550, so it will fit and charge in that camera.

How can I confirm the 2300 mAh battery is working correctly after I insert it?

The camera should power on normally, hold a charge through typical shooting, and the battery-level indicator should read full after a standard charge cycle.

Does the single-pack box include a charger or only the 8.51 Wh Li-ion cell?

The pack contains one FNP120 battery only; a compatible charger must be purchased separately if you do not already have one.
