Four-pack NP-FH50 kit for Sony owners

The set includes four lithium-ion NP-FH50 batteries rated at 1200 mAh and 7.4 V plus an LTD2 dual-slot USB charger. It targets owners of compatible Sony Handycam, Cyber-shot and Alpha models who need multiple spares for long shoots or travel. The charger accepts Micro-USB and Type-C input so it can run from common power banks or wall adapters.

Thermals, noise and power draw in use

Each cell stores 8.88 Wh and the charger delivers 8.4 V at 800 mA per slot with a 5 V, 2–3 A, 15 W input limit. Lithium-ion chemistry runs cool during normal charging and the unit has no fan, so operation is silent. The LCD panel shows real-time capacity and status without adding measurable heat.

Build integration and what it frees up

The charger measures 5 by 3 by 3 inches and ships with a Micro-USB cable, letting it draw power from any 5 V USB source. Swappable plates allow the same dock to charge other NP-F series packs, reducing the number of dedicated chargers a kit requires. Buyers who need simultaneous charging of more than two batteries or a higher-output DC barrel input will need a different solution.

Questions about this item

How do I install the NP-FH50 batteries into the LTD2 charger without inserting them the wrong way?

Align the gold contacts on each battery with the matching pins inside the charger slots, then slide the battery down until it clicks; the LCD will show a charging icon only when the polarity is correct.

What maintenance will the four NP-FH50 batteries need after a year of regular use?

Store them at roughly half charge in a cool dry place, top them up every three months, and replace any cell that no longer holds 8.88 Wh or shows swelling.

Which limit appears first when I charge two batteries continuously from a 5 V 2 A USB port?

The charger’s 800 mA per slot output becomes the bottleneck, so both batteries charge at the same rate regardless of the port’s higher current capability.
