CipherLab RS38 5500mAh Li-ion Replacement Battery (KBRS381455503)

Restore full-shift productivity to your CipherLab RS38 mobile computer with this direct-form-factor replacement battery. Unlike generic packs that may compromise fit or charging behavior, this unit mirrors the original KBRS381455503 cell geometry, connector placement, and electrical profile, so the terminal recognizes it instantly and charges without error. A 5500 mAh lithium-ion core delivers ample runtime for high-volume scanning, inventory counts, and field data collection, while integrated protection circuits guard against overcharge, over-discharge, and short circuits.

Highlights

• Drop-in replacement for CipherLab RS38 handheld terminals
• 5500 mAh capacity at 3.85 V (21.175 Wh)
• User-replaceable, no tools required
• Overcharge, over-discharge, and short-circuit protection
• CE and RoHS compliant

In daily use

The pack slides securely into the RS38 battery compartment and locks with the original latch, maintaining a stable connection during repeated scanning and movement. Because the cell chemistry and discharge curve match the OEM specification, the terminal’s battery gauge remains accurate, and charging via the standard cradle or USB-C adapter proceeds normally. Expect typical cycle life of 300–500 charges to 80% capacity, depending on usage patterns and operating temperatures (0 °C to 40 °C).
