It fits the Bostitch BCF28WWB cordless finish nailer, BCF30PTB, BCN680D1, and the 28-degree wire weld cordless framing nailer, among others. The OEM part numbers BCB204, BCB204-10, and BCB203 all cross-reference to this pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across the Bostitch 20V nailer platform:\u003c\/strong\u003e\n    These nailers share a common 20V battery rail and connector footprint. The BMS handshake protocol is consistent across the BCF and BCN series, so one pack services the full line without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a BCF28WWB and monitored the BMS response during rapid trigger sequences. The overcurrent protection reset cleanly between nail-drive events, and cell voltage held steady across a full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNailer-specific break-in tip:\u003c\/strong\u003e\n    On first use, fire at a moderate pace for two full magazines before running continuous rapid-fire sequences — this lets the BMS log the inrush current spike from the driver mechanism before it locks overcurrent thresholds.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on trigger-pull inrush during rapid nail driving\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eEvery time the BCF28WWB fires, the solenoid or drive motor pulls a sharp current spike at the moment of actuation. If the BMS has not profiled this inrush pattern — common with a fresh or storage-rested pack — it may read the spike as a fault and cut output. This manifests as the tool going dead mid-sequence, then recovering after a few seconds. Running two or three slower break-in cycles gives the BMS enough data to set a stable overcurrent threshold for this tool's specific load signature.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinks red and won't accept the pack after storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs stored without a maintenance charge can drop below the charger's acceptance voltage — typically under 2.5V per cell. Most Bostitch 20V chargers won't initiate a full charge cycle below this threshold, and instead signal a fault with a red blink pattern. To recover the pack, some chargers have a \"wake\" or \"force\" mode; if yours does not, a brief trickle charge from a compatible lab supply to bring cell voltage above 3.0V per cell will allow the standard charger to take over. Check the total pack voltage first — a fully discharged 5-cell 20V pack should read above 15V before the charger will accept it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416028643418,"sku":"BWCS-BCF280PW-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416028676186,"sku":"BWCS-BCF280PW-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416028708954,"sku":"BWCS-BCF280PW-3","price":114.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCF280PW-1.webp?v=1779759460","url":"https:\/\/batteryweb.com\/products\/bostitch-bcf28wwb-replacement-battery-20v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
