Compatible Symbol WT Series Battery

This Centenex Electronics DS-CS-ET4070BL is a 3.4 Ah lithium-ion replacement battery built for Symbol WT4000, WT4070, WT4090 and WT41N0 mobile computers. It suits operations that need a fresh power source for existing fleet devices.

Simple Drop-In Installation

The pack fits the original battery cavity without tools or cable adaptation and ships at 100 percent OEM compatible condition. The only common issue is forgetting to seat the locking latch fully, which can cause intermittent contact during vehicle-mounted use.

Steady Output Across Full Shift

Rated at 3.7 V and 12.58 Wh, the cell maintains consistent voltage through a typical warehouse shift rather than sagging after a short burst. Capacity remains stable across repeated charge cycles in temperature-controlled environments.

Questions about this item

How can I confirm the 3.7 V 3400 mAh battery is working after installing it in my WT4070?

Insert the pack, power on the WT4070 and verify the on-screen charge indicator shows full capacity and the scanner operates through a full shift without unexpected shutdowns.

What comes in the box and what must I source separately for the DS-CS-ET4070BL?

The package contains one 3.4 Ah Li-ion battery; the WT4000-series cradle, charger and scanner itself are sold separately.

Which capacity should I choose between the 3.4 Ah pack and other options for the WT4090?

The DS-CS-ET4070BL is offered only in the 3.4 Ah 3.7 V configuration, so select this model when replacing part numbers 55-000166-01 or BTRY-WT40IAB0E.
