Replacement Power Kit for Sony Handycam

The Kastar NP-FM50 kit supplies four lithium-ion batteries and a matching AC wall charger. Each cell delivers 7.4 volts and 2300 milliampere-hours for a total energy rating of 17 watt-hours. The bundle targets owners of compatible Sony Digital8 and MiniDV camcorders who need spare power for long shoots.

Charger Input Limits and Output Rate

The wall unit accepts 100 to 240 volts at 50 to 60 hertz and provides a fixed 8.4-volt, 600-milliampere DC output. That current ceiling means a fully depleted 2300-milliampere-hour pack requires several hours to reach the green-LED full-charge indication. The foldable flat pins help with storage but do not alter the electrical limits.

Simple Drop-In Install With Polarity Check

Batteries slide into the camcorder or charger exactly like the original Sony NP-FM50 units; no tools or firmware steps are needed. The only common issue is inserting a pack backwards, which prevents contact and leaves the charger LED on green. Verifying the notch orientation before pushing avoids that delay.

Questions about this item

Should I pick the 4-battery pack or buy single batteries?

The kit includes one charger and four 2300 mAh batteries so you can keep spares charged and swap them without waiting.

What does the 2300 mAh rating mean when I am filming?

Each 7.4 V 2300 mAh cell stores 17 Wh, giving roughly one hour of continuous recording on typical camcorders before a swap is needed.

How does the AC wall charger work and what does its output limit?

The foldable-plug charger accepts 100-240 V AC and delivers 8.4 V at 600 mA, so each battery takes several hours to reach full charge.
