CipherLab KBRS381455501 4500mAh Replacement Battery
The KBRS381455501 is the standard hot-swappable 4500mAh Li-ion battery pack for the CipherLab RS38 and RS38H series mobile computers. If your RS38 fleet is holding shorter shifts than it used to, or you're provisioning spares for a warehouse or field-service deployment, this is the factory-new battery to standardize on rather than running degraded cells past their useful cycle life.
Compatibility
KBRS381455501 is built for the CipherLab device line, specifically the RS38 / RS38H mobile computer series. It is the standard-capacity option in CipherLab's two-tier battery lineup for this platform — CipherLab also offers an extended 6800mAh pack (315g installed weight vs. 268g for the 4500mAh version) for crews that need to push past a single shift without a swap. Rated runtime on the 4500mAh cell is 14+ hours per the RS38 platform data, which covers a standard 8-10 hour shift with margin; if your routes run overnight or span two shifts back-to-back, the extended-capacity pack is the better fit rather than carrying a second spare of this one. As a hot-swappable design, the battery pulls from the RS38's 8-pin I/O interface without powering down the unit during a swap — worth planning into your mobile computer hot-swap rotation if you're running these on continuous shifts.
Charging and Runtime
The 4500mAh cell reaches full capacity in 2 hours on a standard charge cycle, roughly a third faster than the extended 6800mAh pack's 3-hour cycle — a meaningful difference if you're rotating batteries through a shared charger during a shift change rather than overnight. Pair it with CipherLab's 4-slot battery charger or 4-slot terminal-and-battery charger for staged charging across a fleet, keeping swap-ready cells on hand instead of waiting on a single-slot cradle. For planning spares and charger capacity across a deployment, a device provisioning and battery lifecycle guide is worth a look before ordering in bulk.
Installation Notes
The battery is a direct hot-swap fit for RS38 and RS38H units — no tools required, and no impact to device configuration or session state during the swap given the platform's hot-swap support. Confirm your unit is running the RS38 platform (not a different CipherLab series) before ordering, since battery contacts and capacity ratings are model-specific and not interchangeable across CipherLab's broader handheld lineup. KBRS381455501 ships as a standalone cell — it does not include a charging cradle, dock, or rubber boot; those are ordered separately from CipherLab's RS38 accessory line if you don't already have charging infrastructure in place.
