About this replacement
Paslode IM350ct / IM325 Series — 7.4V Li-ion Replacement Battery (BCPAS-404717)
This is a 7.4V 2000mAh Li-ion battery for the Paslode IM350ct, IM325, IM250A, and IM250A LI cordless nailers, plus over a dozen additional IM-series models. It replaces OEM part numbers BCPAS-404717, 404717, 902654, 902600, and B20543A among others. The battery slots into the same port as the original and works with the existing Paslode charger.
- IM-series compatibility: These nailers share a 7.4V two-cell Li-ion architecture with the same connector footprint and BMS handshake protocol. The IM350ct, IM325, IM250A, and related models all draw from the same voltage rail and use the same charge-communication circuit — which is why one pack fits the whole platform.
- Bench tested on actual hardware: We cycled this pack on an IM350ct under full nail-driving loads. The BMS tracked motor-start inrush on each trigger pull without tripping, and the cells held voltage above the BMS low-cutoff threshold through sustained framing sequences.
- Break-in on the job site: Run the nailer at a moderate pace through two full magazines before pushing it at maximum rate on dense hardwood framing. This lets the BMS log real inrush data from your specific tool before it locks overcurrent protection thresholds.
BMS cutoff on IM350ct trigger-pull inrush spike
Every trigger pull on a cordless nailer demands a sharp current surge — the firing solenoid draws several times the steady-state load in the first milliseconds. If the BMS overcurrent threshold is set conservatively from factory defaults, that spike can trip a protective cutoff before the nail leaves the magazine. A worn cell with elevated internal resistance makes this worse because voltage sags deeper on inrush, pushing the BMS closer to its trip point. Keeping the battery pack contacts clean and seating it fully in the port reduces contact resistance, which lowers the voltage sag on each shot.
Charger not recognising the pack after storage
Li-ion cells that sit unused for several months can self-discharge below the charger's acceptance threshold — typically around 2.5V per cell, or 5.0V for this 2S pack. Most Paslode chargers refuse to begin a charge cycle if they detect voltage below that floor, so the LED blinks or stays dark entirely. Place the battery in the charger, wait 5 minutes, then remove and re-seat it — some chargers deliver a brief trickle pulse on reinsertion that nudges the pack above the acceptance threshold. If the charger still won't engage, check each cell pair with a multimeter; anything above 2.5V per cell should recover on a slow charge.
