Kastar FNP120 3-Pack Li-Ion Battery 3.7V 2300mAh 8.51Wh

Three-pack lithium-ion replacement

This Kastar FNP120 set supplies three 3.7 V, 2 300 mAh cells rated at 8.51 Wh each. They are built as direct replacements for Motorola Symbol MC1000, Intermec Norand CK1 and CN1, and Wasp WDT-series barcode scanners. Warehouse teams and field-service engineers can keep spare packs on hand without sourcing multiple SKUs.

Single-cell voltage and capacity ceiling

Each cell delivers a fixed 3.7 V nominal output and 2 300 mAh capacity; the scanner’s charging circuit and firmware control the charge profile, so run-time cannot exceed what the host device allows. The integrated protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating, but it does not increase the fundamental energy limit of the chemistry.

8.51 Wh per battery decides fit

The 8.51 Wh rating is the single figure that determines whether the pack fits the power budget of the target scanner models listed. If a device requires a higher watt-hour cell for a full shift, this pack will fall short; if the original spec matches 8.51 Wh, the three-pack restores the intended duty cycle.
