Four-Battery Kit With Wall Charger

This set includes four lithium-ion batteries and a folding-pin AC charger for Sony Handycam camcorders. It replaces the original NP-FV50 power packs used in models such as the HDR-PJ780, HDR-PJ790, HDR-PJ810, HDR-PJ820 and HDR-TD series. Videographers who need spare cells for long shoots can swap batteries without hunting for a proprietary dock. The kit suits event, travel and documentary work where mains power is not always reachable.

1550 mAh Capacity Per Cell

Each battery stores 1550 mAh at 7.2 V, delivering 11.16 Wh of energy. That single figure determines how long the camcorder runs before a change is needed. Users recording continuous 1080p footage should plan for one battery per session block; multi-camera operators can rotate the four cells to keep every angle live. The capacity matches the original Sony specification, so runtime expectations stay familiar.

Steady 600 mA Charge Current

The wall adapter feeds a constant 8.4 V at 600 mA, so a depleted cell reaches full charge in a predictable window rather than a rapid burst. Red and green LEDs show the active and complete states, letting the operator glance at the rack and know which pack is ready. Because the current is modest, the cells stay cool during overnight top-ups in a gear bag. The fold-flat plug keeps the charger slim for travel cases.

Questions about this item

What does the 1550mAh capacity mean for actual recording time on my camcorder?

The 1550mAh rating at 7.2V gives 11.16 Wh per battery; real recording time depends on the camcorder model and settings such as LCD brightness and codec.

What does the charger's 8.4V 600mA output limit in practice?

It caps the charge current at 600 mA, so each NP-FV50 battery takes roughly 2.5 to 3 hours from empty to the green-LED full indication.

Will the foldable flat plug fit a standard UK wall socket without an adapter?

The charger accepts 100–240 V AC, but the foldable flat pins are North-American style; a UK plug adapter is required for British sockets.
