What this battery replaces

The KingSener CF-VZSU46 is a 9-cell lithium-ion pack rated at 10.65 V and 8550 mAh. It is built as a direct replacement for Panasonic Toughbook CF-30, CF-31 and CF-53 series laptops. The silver-coloured unit uses cells made in Japan and ships in new condition.

Installing the pack

Power down the notebook and disconnect the AC adapter before removing the old battery. Slide the release latch, lift the pack out, then press the new unit firmly into the bay until the latch clicks. A loose fit usually means the latch has not fully engaged; reseat the battery and listen for the click.

Runtime and capacity limits

The 8550 mAh rating sets the total energy the pack can store, so actual run time depends on the workload and power settings of the Toughbook. Heavy CPU load, bright screen backlight and active radios will drain the cells faster than light office use. The lithium-ion chemistry also loses a small fraction of capacity with each full charge cycle over the battery’s service life.
