Fits Ratiotec Rapidcount Compact cash counter; replaces OEM battery ZSLP585860x3.
10.8V, 2000mAh Li-Polymer pack delivers 21.6Wh to sustain bill counting and register functions during mains failure.
Connector seats into the register's battery slot with positive terminal forward; locking tab engages on both sides.
Bench testing confirms BMS accepts charge from the register's internal trickle circuit; no fault codes on first insertion.
Leave the register plugged into mains power for 12 hours after installation — the backup battery charges through the register's dedicated circuit and cannot protect programmed prices until fully charged.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions

My Rapidcount Compact loses its count settings every time the power goes out — will a new battery fix this?

Yes, if the existing battery has degraded below the voltage needed to hold the device's volatile memory during a mains interruption. The Rapidcount Compact stores operator settings in RAM that requires a live supply to retain data — when the battery can no longer sustain that rail, settings reset to factory defaults at every outage. Fit the new pack and leave the unit on mains for 12 hours so the trickle charger brings the cells to full capacity before testing. Once fully charged, the battery should hold the memory supply long enough to bridge any normal power interruption.

The display on my Rapidcount Compact goes blank the moment mains power drops, even with the battery fitted — what's happening?

The display backlight and drive circuitry pull more current than the memory-hold circuit alone. If the battery pack is partially discharged or the cells have degraded unevenly across the three-cell series string, the voltage sags under that combined load and the display shuts off even though the unit may still be running internally. Check the pack's resting voltage — it should sit at or above 11.4V after a full charge cycle. If the voltage is below that after 12 hours on mains, the cells have lost capacity and replacement is the correct fix.

My Rapidcount Compact battery seems to go flat within a few weeks of fitting a new one — is the charger damaging it?

Continuous trickle charging at incorrect voltage is the most common cause of accelerated Li-Polymer capacity loss in counters like this. If the Rapidcount Compact's charge circuit voltage drifts above the correct float level — which can happen with a faulty charging board — the cells experience chronic overcharge stress and degrade within weeks. Check that the charging board output is within the expected range for a three-cell Li-Polymer pack: approximately 12.6V at full charge, tapering to a trickle at that point. If the board is outputting higher than 12.6V continuously, the charger circuit needs service before fitting any replacement pack.
