It slots into the original battery port and restores full motor drive to the tool. Capacity is 1500mAh (21.6Wh), matching the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3610 series battery platform:\u003c\/strong\u003e\n    The 3610, 3610-K10, 3612, and 3615 share the same 14.4V pack format, contact layout, and charge termination logic. A single battery chemistry revision covers all four models without adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated trigger-pull sequences on a 3612 body. The BMS handled motor-start inrush without tripping, and delta-V cutoff on the charger triggered correctly at full charge on each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst two cycles on this Ni-MH pack:\u003c\/strong\u003e\n    Run the drill at half load — light drilling, no high-torque fastening — for the first two discharge cycles. This lets the BMS log the motor's inrush current draw before the overcurrent threshold locks in at full torque demand.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS overcurrent trip on trigger-pull inrush in the 3610 series\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a Skil 3610-class drill, the motor draws a spike of current before it reaches running speed — often three to five times the steady-state draw. A fresh or recently stored Ni-MH pack has slightly elevated internal resistance, which amplifies the voltage dip at that spike. If the BMS reads that dip as an overcurrent fault, it cuts the output rail before the motor completes its start cycle. Running the pack through two half-load cycles normalises cell resistance and gives the BMS accurate inrush data, which prevents nuisance trips at full torque.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows no activity or won't accept the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if a pack sits long enough, cell voltage drops below the charger's acceptance threshold — typically around 1.0V per cell. The Skil charger checks for a minimum voltage before beginning the charge cycle, so a deeply discharged pack looks like a fault rather than a dead battery. To recover it, apply a brief trickle charge at low current — some chargers have a manual recovery mode, or a bench supply set to 14.4V at 100mA for 10–15 minutes will bring cells above the acceptance floor. Once the pack reads above roughly 10.8V total, the standard charger will accept it and complete a full charge cycle normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416082645082,"sku":"BWCS-BSR144PW-1","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416082677850,"sku":"BWCS-BSR144PW-2","price":100.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416082710618,"sku":"BWCS-BSR144PW-3","price":111.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSR144PW-1.webp?v=1779760222","url":"https:\/\/batteryweb.com\/products\/skil-3610-replacement-battery-144v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
