Sony NP-FZ100

Wasabi Power Sony NP-FZ100 Battery — Affordable Insurance for Long Shooting Days

The gist: A 2000mAh third-party replacement for the Sony NP-FZ100 that displays remaining charge in-camera and backs its cells with a 3-year warranty — a cost-effective spare for travel days where running out of power means missing the shot.

• Fully decoded charge display: Remaining battery percentage shows in your camera’s viewfinder and info display, so you know exactly how much run time is left while shooting in the field.
• Works across the Sony a7/a9 ecosystem: Compatible with the a7 III, a7 IV, a7C, a7R III, a7R IV, a7S III, a9, and a9 II without adapters or firmware workarounds.
• 3-year manufacturer warranty: Covers defects over a full travel camera lifespan — significantly longer than most third-party battery warranties at this price point.
• ~$25 per battery: Two Wasabi batteries cost less than one OEM NP-FZ100, making it practical to carry a spare without straining the travel budget.

Wasabi Power states all batteries meet or exceed OEM electrical standards using Premium Grade A cells at 7.2V and 2000mAh — note the Sony OEM NP-FZ100 is rated 2280mAh, so OEM batteries provide slightly more capacity per charge.

Best for: Sony a7-series or a9-series travel photographers who want affordable spare batteries without paying OEM prices. Skip it if: You’ve updated a Sony FX3 to firmware 4.0 — that update blocks third-party batteries from functioning. Runs ~$25 — check the current price before buying.
