Compatible replacement battery

The GreenTech CF-VZSU75JS is a 4-cell lithium-ion battery built for Panasonic CF-SX1, CF-SX2, CF-NX1 and CF-NX2 laptops. It replaces OEM part numbers CF-VZSU75JS and CF-VZSU75 with a 47WHR capacity at 7.2V. The unit is new and tested for correct voltage and circuit protection before dispatch. It suits owners of those specific Panasonic models who need a direct swap.

Thermals and power behaviour

The 6800mAh lithium-ion chemistry delivers stable current with low self-discharge during normal mobile use. CE, FCC and RoHS certifications confirm the pack meets recognised safety standards for voltage regulation and circuit protection. No active cooling is required because the battery operates passively inside the laptop chassis. Typical operation remains quiet and within the thermal envelope of the original design.

Sustained load characteristics

Under continuous discharge the 4-cell pack maintains the rated 7.2V output until the protection circuit intervenes at the low-voltage threshold. The 47WHR energy rating reflects capacity measured under standard test conditions rather than a peak burst figure. Rigorous pre-ship testing verifies that each unit holds the specified capacity over repeated cycles. Users who need longer runtimes than 47WHR provides should consider a higher-capacity alternative if one exists for their model.

Questions about this item

How do I install the CF-VZSU75JS battery in my Panasonic CF-SX2, and what step do people often miss?

Power off the laptop, remove the AC adapter, slide the old pack out, insert the new 4-cell lithium-ion unit until the latch clicks, then charge it fully before first use; the step many skip is that full initial charge.

What maintenance or replacement will this 6800mAh pack need later?

Expect gradual capacity loss over hundreds of cycles; when runtime drops below your needs, replace the pack — lithium-ion cells are not user-serviceable and the 7.2V 47WHR unit has no calibration routine.

What limit appears first during sustained use of this 7.2V battery?

The 47WHR capacity sets the runtime ceiling; under continuous load the pack will hit its depth-of-discharge limit and trigger the laptop's low-voltage shutdown before thermal limits become a factor.
