DS-CS-SWT400BU CMOS battery for Symbol WT4000 series

This green Ni-MH cell supplies 2.4 V and 20 mAh to keep the real-time clock running on Symbol WT4000, WT4070, WT4090, WT4090I, WT4190 and WT41N0 VOW handhelds. It replaces part number CS-SWT400BU and arrives new in OEM-compatible condition.

Voltage and capacity match the original spec

The cell delivers exactly 2.4 V and 0.02 Ah so the motherboard receives the same trickle current the factory battery provided. A different voltage or capacity would prevent the CMOS from retaining date and BIOS settings.

Steady low-current output over years

Ni-MH chemistry maintains a stable 2.4 V while drawing only micro-amps from the board, so the battery lasts through extended deployments without the voltage sag that can corrupt CMOS data during long idle periods.

Questions about this item

How long will the 2.4 V 20 mAh cell keep the real-time clock running inside a Symbol WT4000?

The 20 mAh Ni-MH cell supplies the tiny current a CMOS clock draws, so it typically lasts several years before the clock loses time.

Does the two-wire connector match the original Symbol WT4070 CMOS header?

Yes, the DS-CS-SWT400BU is built to the same pin-out and voltage as the factory CS-SWT400BU part for WT4070, WT4090 and WT4190 units.

Will the 19.17 x 11.97 x 7.70 mm green pack fit the WT4090I battery compartment?

Those exact dimensions match the OEM cavity, so the pack slides in without forcing the cover or bending contacts.
