About this replacement
Ratiotec Rapidcount Compact — 10.8V Li-Polymer Replacement Battery (ZSLP585860x3)
This 10.8V, 2000mAh Li-Polymer battery replaces the original ZSLP585860x3 cell pack in the Ratiotec Rapidcount Compact portable cash counter and currency sorter. It powers bill counting, sorting, and the onboard display during both mains and battery operation. Capacity is 21.6Wh, matching the original specification exactly.
- Rapidcount Compact fit: The Rapidcount Compact uses a three-cell Li-Polymer pack wired in series to reach the 10.8V rail the counting motor and display controller share. The ZSLP585860x3 format — 62.10 × 46.00 × 15.00mm — is specific to this chassis. No other Ratiotec pack fits this bay without connector or BMS conflicts.
- Bench tested on actual hardware: We cycled this pack through the Rapidcount Compact's charge and discharge circuit. The BMS balanced all three cells correctly, held the low-voltage cutoff at the expected threshold, and the device completed full counting cycles without triggering a fault shutdown.
- First-charge protocol for the Rapidcount Compact: After fitting this battery, connect the Rapidcount Compact to mains and leave it charging for a full 12 hours before running a counting cycle on battery alone. The device uses a slow trickle charger — the pack will not reach usable capacity from a short top-up charge.
Why the Rapidcount Compact stops mid-count when unplugged from mains
The counting motor draws a sharp current spike each time a note passes the sensor. If the battery pack has aged or was never fully charged after installation, that spike can pull the cell voltage below the BMS cutoff threshold, triggering an immediate shutdown. This looks like a software fault but is purely electrical — the device cuts power to protect the cells. Fitting a fresh pack and completing the 12-hour trickle charge before first use eliminates this failure mode in the large majority of cases.

Li-Polymer cells lose charge during storage, so a new pack can arrive at 30–40% state of charge. The Rapidcount Compact's battery indicator reads cell voltage directly — a resting voltage below approximately 10.0V will display as low or critical even on a brand-new battery. Connect the unit to mains straight away and allow a full charge cycle. Once the pack reaches 12.6V at rest, the indicator will read correctly and counting on battery power will behave normally.
