Two-pack replacement batteries for Sony camcorders

This Kastar twin-pack supplies two lithium-ion cells rated at 7.4 V and 1 200 mAh each, matching the NP-FP50 and NP-FP51 form factor. They fit a long list of Sony Handycam models from the DCR-DVD, DCR-HC, DCR-SR and HDR-HC series. The pack is intended for owners who need a spare or a direct replacement without sourcing original Sony cells.

Thermal behaviour and power delivery

Lithium-ion chemistry runs cool during typical recording sessions and the built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. No fan or active cooling is involved, so operation stays silent. Each cell stores 8.88 Wh and meets UL 1642 and CE safety standards.

Capacity per cell

The decisive figure is 1 200 mAh at 7.4 V, giving 8.88 Wh per battery. Buyers who need longer runtimes per charge or higher-capacity cells such as the NP-FP70 or NP-FP90 series should look elsewhere.

Questions about this item

How do I install the Kastar NP-FP51 battery in my Sony DCR-DVD202, and what is the common mistake?

Slide the battery into the compartment until the latch clicks; the step people miss is not pressing firmly enough to engage the lock, leaving the pack loose.

What maintenance will the 1200mAh Li-Ion pack need later?

Store at roughly half charge in a cool place when unused for weeks; no calibration is required, but capacity will gradually decline over time.

What limit appears first during sustained recording with the 7.4V 8.88Wh cells?

The protection circuit will cut power if the pack overheats or current exceeds its safety threshold, stopping the camcorder before the cells are damaged.
