All three tools share the same voltage rail and battery connector format. Capacity is 2100mAh (15.12Wh) as specified in the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGCN40T, GF28WW, GF33PT platform fit:\u003c\/strong\u003e\n    These three nailers run the same 7.2V Ni-MH pack because they share a common battery bay geometry, connector pinout, and voltage requirement. Swapping between models does not require any 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 through full charge and repeated nail-driving sequences on the GCN40T. The BMS handled inrush current on each trigger pull without tripping, and cell voltage held stable across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for Ni-MH nailer packs:\u003c\/strong\u003e\n    Run the nailer at moderate load for the first two full cycles before using it on continuous heavy drives. Ni-MH cells need a few full charge-discharge passes to reach rated capacity — pushing maximum cycle rate from the first use can leave you short of full output from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GCN40T cuts out mid-sequence on rapid trigger pulls\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCoil nailers draw a sharp inrush spike each time the solenoid or drive mechanism fires. On rapid sequential shots, these spikes stack before the cells recover voltage between pulls. If the pack is aged or has been stored discharged, internal resistance rises and the BMS reads the voltage drop as an overcurrent event. The result is a mid-sequence cutout even though the battery showed a full charge indicator before you started. Slowing the firing cadence slightly lets the cells recover between shots and keeps the BMS from tripping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs that have sat in a warehouse can self-discharge below the voltage threshold the Bostitch charger uses to confirm a valid battery is present. The charger sees a voltage too low to begin its normal charge profile and either does nothing or shows a fault. To recover the pack, check cell voltage with a multimeter — if it reads above approximately 5.0V total (around 0.7V per cell), the pack is recoverable. Place it on the charger for a short period, remove it, and reinsert it to prompt the charger to re-check and accept the pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416067801178,"sku":"BWCS-HTB712PW-1","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416067833946,"sku":"BWCS-HTB712PW-2","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416067866714,"sku":"BWCS-HTB712PW-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTB712PW-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/bostitch-gcn40t-replacement-battery-72v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
