Two-pack replacement for Sony NP-FF50 series

This two-pack replaces Sony NP-FF50, NP-FF51 and NP-FF51S batteries. It fits a wide range of Sony Handycam models including the DCR-HC1000, DCR-IP series, DCR-PC series and others listed by the supplier. Each cell is a 7.2 V lithium-ion unit rated at 900 mAh and 6.48 Wh.

Capacity and headroom for extended shooting

The 900 mAh capacity provides longer run time than lower-rated alternatives, supporting extended recording sessions on compatible camcorders. When the charge is depleted the pack must be recharged before further use, so a second battery in the pack keeps the camera running while the first recovers.

7.2 V lithium-ion chemistry with protection circuits

The decisive specification is the 7.2 V lithium-ion chemistry combined with built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection. Buyers whose camcorders require a different voltage or chemistry cannot use this pack.

Questions about this item

Will these 7.2 V 900 mAh packs run in my DCR-HC1000 alongside the original NP-FF50?

Yes — they are direct replacements for the Sony NP-FF50, NP-FF51 and NP-FF51S cells used in the DCR-HC1000 and DCR-HC1000E.

How do I know each cell is delivering the rated 6.48 Wh after I install it?

The built-in protection circuit prevents over-charge, over-discharge, over-voltage, over-current and over-heating; normal camcorder operation and expected run-time confirm it is working.

What comes in the 2-pack box and what must I source separately?

Two Kastar NP-FF50/NP-FF51/NP-FF51S lithium-ion batteries are included; a compatible charger is not supplied.
