Four-pack of 7.2 V 1800 mAh Li-ion camera batteries with UL1642 and CE safety protection
Model 4 Packs
This four-pack of Kastar NP-FF70 lithium-ion batteries replaces Sony NP-FF50, NP-FF51, NP-FF70 and NP-FF71 series cells. It fits Handycam models including the DCR-HC1000, DCR-IP series, DCR-PC106 through DCR-PC109 and DCR-PC350. Each cell delivers 7.2 V and 1800 mAh for extended recording sessions.
The NP-FF70 footprint restricts capacity to 13 Wh per cell, so runtime scales linearly with the number of packs you carry. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating, but they also cap peak current to the cell's rated limits. No higher-capacity version exists in this physical size.
Verify that your Handycam accepts NP-FF70, NP-FF71 or NP-FF50 type batteries; the compartment will not accept larger NP-F series packs. Confirm the charger you own supports 7.2 V lithium-ion cells with the same contact layout. If your model requires a different voltage or form factor, these cells will not fit or charge correctly.

Other versions of this model
The 4-pack gives you four 1800 mAh Li-Ion cells at once, so you can keep spares charged and swap them during long shoots without waiting for a single battery to recharge.
At 7.2 V and 1800 mAh the pack stores 13 Wh; real recording time depends on the camcorder's power draw, but the capacity matches the original Sony NP-FF70 specification.
The battery uses the standard Sony NP-FF series connector, so it fits every listed model from DCR-IP5 to DCR-PC350E and charges in the original Sony charger without any speed restriction.
