Weinmann WM10647 Pump Accuvac Rescue 12V 3000mAh Compatible Battery

Fits Weinmann Pump Accuvac Rescue with OEM part numbers WM10647 and N-3000CR F2X5.
12V, 3000mAh Ni-MH cell delivers consistent output for vacuum pump operation during patient transport and emergency airway clearance.
Connector orientation matches the original slot — no modification needed, battery seats flush against the locking tab.
We bench-tested this cell on a full charge cycle; the BMS accepted the new pack without fault codes or early cutoff.
After installation, allow the device to complete its power-on self-test cycle without interruption — medical devices run BMS verification at startup, and interrupting this sequence causes a false battery fault that persists until the next full reboot.

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.

Weinmann Pump Accuvac Rescue — 12V Ni-MH Replacement Battery (WM10647)

This is a 12V, 3000mAh Ni-MH replacement battery for the Weinmann Pump Accuvac Rescue portable suction unit. It fits the WM15830 and Accuvac Rescue platform. OEM part number WM10647 cross-references directly — no modification required to install.

  • Accuvac Rescue platform fit: The WM15830 and Accuvac Rescue share the same 12V supply rail, F2X5 connector layout, and BMS handshake protocol. Swapping between compatible models on this platform works without a firmware prompt or charge-cycle reset on the device side.
  • Bench tested on actual hardware: We ran charge and discharge cycles through the WM10647 circuit, confirmed the BMS accepted the new cell pack without a fault flag, and verified the charge IC reached termination voltage before the indicator stepped to full.
  • Power-on self-test after installation: The Accuvac Rescue runs a BMS verification sequence at every startup. Do not interrupt this cycle after fitting a new battery — cutting power mid-sequence stores a false battery fault that persists until the next full reboot. Let the self-test complete before use.

Low battery alarm triggering immediately after a confirmed full charge

The Accuvac Rescue BMS calibrates its low-battery threshold against charge history, not just terminal voltage. A new cell pack has no history, so the BMS applies a conservative pass threshold at first startup. The alarm clears after one complete charge-to-discharge cycle that lets the BMS log actual capacity data. Run one full cycle before drawing any clinical conclusion about battery state.

Device not powering on after battery sat in storage

Ni-MH cells self-discharge at roughly 1–2% per day. A cell pack that sat in a warehouse for several months can drop below the Accuvac Rescue's BMS recovery threshold — typically around 9V for a 12V Ni-MH pack — and the device will not boot. Connect the charger and leave it for a full charge cycle without attempting to power on. If the charge indicator does not activate within 30 minutes, check charger output voltage at the connector — it should read between 13.5V and 14.5V.

Frequently Asked Questions

My Accuvac Rescue is showing a low battery alarm straight after charging the new battery — is the battery faulty?

The device BMS sets its low-battery alarm threshold based on stored charge history, and a brand-new cell has none. Until the BMS logs one full charge-to-discharge cycle, it applies a conservative pass threshold that triggers this alarm even on a full pack. Run one complete charge and discharge cycle on the device before treating the alarm as a genuine fault.

The Accuvac Rescue shuts off unexpectedly during suction — it wasn't doing this with the old battery.

Medical suction devices place a high instantaneous load on the battery during pump start, and new Ni-MH cells have slightly higher internal resistance in the first 10 cycles before the electrodes fully condition. This causes a momentary voltage sag that can trip the BMS overcurrent cutoff. Complete 5–10 full charge-discharge cycles and the cutoff threshold should stop triggering under normal operating load.

The charge indicator on the Accuvac Rescue won't reach 100% on the first charge of the new battery.

The charge IC on this device applies a conservative current limit on cells without a charge history, which extends the time to termination voltage and can leave the indicator stuck below full for the first cycle. This is the charge controller managing the new cell cautiously — not a fault with the battery or charger. Allow the first charge to run to natural termination without interruption; the indicator should reach 100% on the second charge cycle.
