Ingersoll Rand IQV20 BL2012 Replacement Battery 20V 4000mAh

Ingersoll Rand IQV20 Series — 20V Li-ion Replacement Battery (BL2012)

This is a 20V Li-ion battery at 4000mAh (80Wh), replacing OEM part numbers BL2012, BL2010, and BL2022. It fits the IQV20 platform — including the IRC-W7150, IRTW7150, and IRW7150 impact wrenches, plus over 20 additional IQV20-compatible tools. The pack uses the same connector and BMS handshake protocol as the original Ingersoll Rand cells.

• IQV20 platform compatibility: All IQV20-series tools share the same 20V rail voltage and keyed slide connector. The BMS on this pack communicates over the same signal line the charger and tool use to negotiate current limits and thermal thresholds — no adapters or firmware workarounds needed.
• Bench tested on actual hardware: We ran this pack on an IRW7150 impact wrench and cycled it through repeated motor-start events. The BMS handled inrush spikes without tripping overcurrent protection, and cell temperatures stayed within safe range across sustained load cycles.
• Break-in on impact and drill tools: On first use, run the tool at half load for two full discharge cycles before applying maximum torque. This lets the BMS log the motor inrush current profile and set accurate overcurrent thresholds before you hit it with heavy fastening work.

BMS cutoff on IQV20 motor-start inrush surge

When you pull the trigger on a high-torque tool like the IRW7150, the motor draws a spike of current before it reaches operating speed. On a cold or deeply discharged pack, this inrush can exceed the BMS overcurrent threshold in under 20 milliseconds. The BMS interprets that spike as a fault and cuts the output rail — the tool simply stops mid-trigger. Warming the pack to room temperature before use raises internal cell conductance and keeps the inrush spike below the trip threshold.

Charger blinking red on a new or stored IQV20 pack

Ingersoll Rand chargers check cell voltage before entering the bulk charge stage. If the pack has sat in storage and any cell has dropped below approximately 2.5V, the charger rejects it with a red blink rather than beginning a charge cycle. This is a protection feature, not a fault with the charger or the pack. To recover, place the battery in a compatible tool and pull the trigger briefly — if the tool responds even weakly, the cells are above the recovery floor. Then seat it back in the charger immediately while the cells are slightly elevated above 2.5V.
