It fits models 1201, 40394, and other Lincoln 12V units sharing OEM part number 218-787. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1201 and 40394 platform fitment:\u003c\/strong\u003e\n    These models share a common 12V battery bay, connector pin layout, and BMS handshake protocol. The same cell pack and contact configuration covers the full platform, so one replacement battery works across multiple units on the same charger.\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 discharge on a 12V grease gun platform. The BMS held stable through repeated motor-start inrush spikes and did not trip prematurely on cold starts from rest.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in on grease gun duty cycles:\u003c\/strong\u003e\n    Run the tool at light trigger pressure for the first two cycles before pushing full continuous trigger — this lets the BMS log the motor's inrush current draw and calibrate its overcurrent threshold to your specific unit, not factory defaults.\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 grease gun motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA 12V grease gun draws a short, sharp current spike the moment the trigger is pulled — motor-start inrush can hit three to five times the steady running current. If the BMS has no current profile stored from previous cycles, it may interpret that spike as a fault and cut power before the motor reaches running speed. Ni-MH packs are less prone to this than lithium, but a freshly installed replacement pack with no cycle history can still trip a conservative BMS. Run two light-load cycles first to let the BMS record normal inrush before you use full trigger on thick grease or cold fittings.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising pack after storage — red blink, no charge start\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if the pack drops below the charger's acceptance voltage threshold, the charger may refuse to begin a charge cycle and blink red instead. Lincoln 12V chargers typically need to see at least 8–9V at the terminals before the charge circuit opens. To recover a deeply discharged pack, connect it to the charger and leave it for 10–15 minutes — some chargers apply a trickle pre-charge pulse before switching to full charge mode. If the charger still shows red after 20 minutes, check terminal contact voltage with a multimeter; a reading below 7V indicates the pack needs a manual 1A trickle charge to recover.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416061509722,"sku":"BWCS-LIN120PX-1","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416061542490,"sku":"BWCS-LIN120PX-2","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416061575258,"sku":"BWCS-LIN120PX-3","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LIN120PX-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/lincoln-1201-replacement-battery-12v-3300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
