Paslode BID-900 Replacement Battery 9.6V 3000mAh B-9620F2

Paslode BID-900 / BD-90 / BD-72 9.6V Ni-MH Replacement Battery (B-9620F2)

This is a 9.6V, 3000mAh Ni-MH battery for the Paslode BID-900, BD-90, and BD-72 cordless impact drivers and drill/drivers. It replaces OEM part numbers B-9620F2, B-967F1, and B-963F2. Capacity comes from the product data: 3000mAh (28.8Wh).

• BID-900, BD-90, and BD-72 compatibility: These three Paslode models share the same 9.6V battery platform, connector format, and BMS handshake protocol. One pack fits all three without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a BID-900 unit. The BMS held stable through repeated trigger-pull inrush spikes and did not trip under normal fastening loads.
• Ni-MH conditioning on first use: Run the tool through two full discharge-and-charge cycles before using it at maximum torque settings. Ni-MH cells need cycling to reach rated capacity skipping this leaves noticeable capacity on the table early in the pack’s life.

BMS cutoff on motor-start inrush during fastening

Impact drivers draw a sharp current spike the instant the motor engages this inrush can be several times the steady running current. On a new or recently stored Ni-MH pack, the BMS may not yet have a current profile for the motor load, so the overcurrent threshold triggers too early. The BID-900’s motor is particularly prone to this on hard materials where the clutch engages immediately. Running two light-load cycles first lets the BMS calibrate its threshold to the motor’s actual inrush signature.

Tool bogs under load mid-fastening cycle

If the driver feels strong on trigger pull but loses torque partway through a drive cycle, the cause is usually voltage sag the cell voltage drops under sustained load and the tool’s controller reduces output to stay above cutoff. On Ni-MH packs, this gets worse if the cells have been repeatedly shallow-cycled and never fully discharged. Check the rail contacts on both the battery and the tool for oxidation or debris; resistance at that junction amplifies sag. Clean the contacts with a dry cloth and run the pack to full discharge before recharging target a resting voltage of 9.09.6V after a full charge cycle.
