Compatible Sony Camcorder Battery

The Cameron & Co DS-CS-FS21 is a lithium-ion replacement battery for Sony DCR-PC and DCR-TRV series camcorders. It replaces original NP-FS20, NP-FS21 and NP-FS22 packs. The 3.7 V, 2880 mAh cell suits owners needing a reliable spare or primary power source.

Thermals Noise and Power Draw

Lithium-ion chemistry delivers steady voltage with minimal self-discharge during normal camcorder operation. The cell runs cool inside the camera body and adds no audible noise. No charger is included so power draw depends on the original Sony charger used.

What the Bundled Accessories Change

The package contains only the single dark grey battery unit. No charger, cable or mounting hardware is supplied. Buyers must use an existing Sony charger or purchase one separately to recharge the 2.88 Ah cell.

Questions about this item

How do I install the DS-CS-FS21 battery in my Sony DCR-PC1, and which step do people often miss?

Slide the battery into the compartment until the latch clicks; the step users miss is confirming the click, which locks the 52.20 x 30.30 x 42.50 mm pack securely.

What maintenance or replacement will the NP-FS21 compatible battery need over time?

Lithium-ion cells degrade with charge cycles; plan to replace the 2880mAh pack when run-time drops below roughly 80 % of its original capacity.

What limit appears first during continuous recording with this 3.7 V 2.88 Ah battery?

Thermal protection typically triggers before the full 2880mAh is discharged, especially in warm environments or during long takes.
