  • 16 Wh energy rating supports extended mobile use

Direct replacement battery

The Centenex Electronics DS-CS-BUD500BL is a lithium-ion power cell built for the Bluebird EF500R mobile computer. It restores full runtime to handheld scanners used in logistics, retail and field-service roles where a dead pack halts workflow.

Swaps the original BAT-EF500_S pack

This unit replaces the factory BAT-EF500_S battery when its capacity has faded below usable levels. The upgrade is worth it when shift-length scanning sessions can no longer be completed on a single charge and a fresh 3.2 Ah cell returns the device to its original duty cycle.

Delivers steady output across the shift

Rated at 3.8 V and 12.16 Wh, the pack maintains consistent voltage during continuous barcode reading rather than sagging after a brief burst. Its slim 5.70 mm profile fits the EF500R chassis without bulging, so the scanner stays balanced in the hand for hour after hour of inventory counts.

Questions about this item

Will the 80.50 x 53.60 x 5.70 mm case fit my EF500R handheld?

The pack measures exactly 80.50 by 53.60 by 5.70 mm, matching the original Bluebird BAT-EF500_S cavity.

How do I install the 3.2 Ah Li-ion pack without damaging the connector?

Power off the EF500R, slide the old cell out, align the new pack's contacts, press firmly until the latch clicks — do not force it at an angle.

When should I replace the 3200 mAh battery?

Replace it when a full charge no longer lasts a typical shift or the case shows any bulging.
