CipherLab KBRS381455502 RS38H 4500mAh Battery
The KBRS381455502 is the standard hot-swappable 4500mAh Li-ion battery pack for CipherLab's RS38H rugged mobile computer. If you're running RS38H units across a shift-based warehouse or field-service fleet, this is the battery that keeps a device in an operator's hand instead of on a charging dock during peak hours — rated for 14+ hours of working time per charge on the standard capacity cell, with a 2-hour fast charge from 0% to full.
Overview
RS38H deployments live and die on battery logistics. A device that can't survive a shift, or that takes half a shift to recharge, breaks your labor scheduling around the equipment instead of the other way around. The KBRS381455502 is built to be hot-swapped — pull it, drop in a charged replacement, and the RS38H keeps running without a full reboot cycle, which matters when you're rotating dozens of handhelds through a 4-slot or 5-slot charging station between shifts.
Key Features
- 4500mAh Li-ion capacity: Rated for 14+ hours of working time on a single charge — enough to cover a full shift on an RS38H without a mid-shift swap in most single-shift warehouse or delivery operations.
- Hot-swappable design: Pull and replace without powering down the terminal, so a dead battery doesn't mean a lost session on whatever app or WMS screen the operator has open.
- 2-hour fast charge (0% to full): Materially shorter recovery time than a standard overnight-only charge cycle, which matters if your charging station has more terminals than slots during a shift change.
- Rechargeable Li-ion chemistry: Standard lithium-ion construction compatible with CipherLab's single charging cradle, single charging/workstation, and multi-slot battery charger accessories.
- Direct fit for RS38H series: Purpose-built battery pack for the RS38 / RS38H platform — no adapter or bracket needed when replacing a depleted or aging original-equipment cell.
- Shift-scale charging compatibility: Works with CipherLab's 4-slot battery charger and 4-slot battery-and-terminal charger accessories, letting a supervisor stage multiple KBRS381455502 packs ahead of a shift change instead of charging one terminal at a time.
Integration & Compatibility
The KBRS381455502 is designed specifically for the RS38H series and pairs with the same accessory ecosystem as the terminal itself: single charging cradles, 4-slot and 5-slot charging stations, and combination battery-and-terminal chargers. For fleets standardizing on CipherLab mobile computers, keeping a stock of spare KBRS381455502 packs on hand is the standard way to eliminate charging downtime as a bottleneck — pair it with a multi-bay charger from the mobile computer accessories category so batteries are always staged and ready between shifts. If you're scoping a new RS38H rollout, a device selection review with your mobile computing hardware lineup is worth doing before ordering spares in bulk — see our battery and charging planning guide for shift-coverage math. An extended 6800mAh version is also available in the same RS38H accessory line for operations running longer or split shifts where 14+ hours isn't enough headroom.

Frequently Asked Questions
Q: What is the runtime of the KBRS381455502 battery?
A: CipherLab rates the 4500mAh standard battery for 14+ hours of working time on an RS38H terminal, versus 21+ hours on the extended 6800mAh version.
Q: How long does the KBRS381455502 take to charge?
A: The standard 4500mAh battery reaches full capacity in 2 hours from 0%, per CipherLab's fast-charging specification.
Q: Is the KBRS381455502 hot-swappable?
A: Yes. The RS38H platform supports hot-swappable batteries, so the KBRS381455502 can be replaced without powering down the terminal.
Q: What warranty comes with the KBRS381455502?
A: It carries CipherLab's 1-year standard warranty.
Q: Which charging accessories work with the KBRS381455502?
A: It is compatible with CipherLab's single charging cradle, single charging/workstation, 4-slot battery charger, and 4-slot battery-and-terminal charger for the RS38H series.
Q: Is there a higher-capacity alternative to the KBRS381455502?
A: Yes, CipherLab offers an extended 6800mAh battery for the RS38H series rated for 21+ hours of working time, for operations needing longer runtime between charges.
I spec spare batteries for every rugged mobile computer rollout I scope, and the KBRS381455502 is a straightforward one: 4500mAh Li-ion, rated 14+ hours of working time on the RS38H, with a 2-hour full recharge. That runtime-to-recharge ratio is what actually determines how many spares a fleet needs.
Technical Highlights:
- 4500mAh capacity: Delivers 14+ hours of rated working time — enough headroom for a standard single shift on an RS38H without a mid-day swap in most warehouse or delivery workflows.
- 2-hour fast charge (0-100%): Cuts recovery time roughly in half versus a slow overnight-only charger, which matters when a charging bay has fewer slots than active terminals.
- Hot-swap support: The RS38H accepts battery swaps without a forced reboot, so a KBRS381455502 change mid-shift doesn't cost the operator their current app session.
Deployment Considerations:
- Stage spares in a 4-slot or 5-slot charger so a supervisor can rotate depleted KBRS381455502 packs in bulk between shifts rather than one at a time.
- If your shift runs longer than roughly 14 hours or spans two shifts without a charging window, the standard 4500mAh cell will be tight — CipherLab's extended 6800mAh pack (21+ hours) is the better fit, not this one.
Right fit for single-shift warehouse, DSD, or field-service RS38H fleets that need predictable hot-swap battery logistics without over-provisioning for runtime they don't need.
