Product identity and target user

The Centenex Electronics DS-CS-ET4090BL is a lithium-ion replacement battery rated at 3.7V and 2200mAh. It is built for Symbol WT4000, WT4070, WT4090, WT4090i and WT41N0 barcode scanners. The pack matches OEM part numbers 55-000166-01, 82-90005-05 and BTRY-WT40IAB0E.

Fit and exclusions

This unit suits operators who need a direct swap for the original Symbol power cell in the listed handheld terminals. It will not fit scanners outside the WT4000, WT4070, WT4090 or WT41N0 families, nor devices that require a different voltage or connector layout. Buyers needing a higher-capacity pack or a different form factor should look elsewhere.

Sustained operation behaviour

The 8.14Wh cell delivers consistent voltage across a full shift in warehouse or retail environments. Lithium-ion chemistry maintains steady output without the voltage sag seen in older chemistries during prolonged scanning sessions. The 112.20 x 28.40 x 27.60 mm housing sits securely in the scanner cavity, preventing intermittent contact under vibration or repeated insertion cycles.
