NP-FZ100 replacement for Sony Alpha cameras

This Kastar battery replaces the Sony NP-FZ100 and fits a wide range of Alpha bodies including the A9, A9 II, A7 III, A7 IV, A7R III, A7R IV, A7R V, A7C, A6600, FX3 and FX30. It also works with the VG-C3EM grip and the BC-QZ1 or NPA-MQZ1K chargers. One pack contains a single 7.2 V lithium-ion cell rated at 2280 mAh and 16.4 Wh.

Thermal and electrical behaviour

The lithium-ion chemistry runs cool during typical shooting sessions and the built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. The cell meets UL 1642 and CE safety standards so it behaves predictably in normal use.

Upgrading from lower-capacity packs

Photographers replacing an aged original NP-FZ100 or a lower-capacity third-party pack gain longer run time per charge and a safer protection circuit. The jump is worth it when you need extended shooting without swapping cells, but buyers who want more storage for multi-day trips should plan for additional packs.

Questions about this item

How do I install the NP-FZ100 battery in my Sony A7 IV, and what step do people often miss?

Slide the 7.2 V pack into the grip until the latch clicks; the step many skip is confirming the arrow on the label faces the same direction as the camera body mark.

What maintenance will this 2280 mAh Li-Ion cell need over its life?

No scheduled maintenance is required; store at roughly half charge if unused for weeks and keep contacts clean for reliable cycling.

Which limit appears first during continuous 4K recording with this 16.4 Wh battery?

The 2280 mAh capacity typically depletes before thermal protection activates, ending the session.
