It uses OEM part number 92931 and slots directly into the HD3736 battery bay. Voltage and capacity match the original pack spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHD3736 platform fit:\u003c\/strong\u003e\n    The HD3736 runs a 12V Ni-MH rail with a proprietary latch-and-contact housing. This pack matches that connector geometry and cell voltage, so the tool's trigger circuit sees the correct supply voltage from the first pull.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the HD3736 platform under repeated start-load sequences. The BMS held stable through motor-start inrush current spikes and returned to nominal cell voltage within the expected recovery window after each load drop.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in on the HD3736:\u003c\/strong\u003e\n    Run the drill at half load — light drilling, no high-torque fastening — for the first two charge cycles. Ni-MH cells need those cycles to equalise across the pack before the BMS can accurately set its overcurrent thresholds for motor-start inrush.\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 motor-start inrush in the HD3736\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HD3736 motor draws a sharp current spike the instant the trigger is pulled — this inrush can be three to four times the steady running current. On a new or storage-discharged pack, the BMS has no inrush profile logged and may trip the overcurrent threshold as a precaution. Running two break-in cycles at partial load lets the BMS calibrate its current window to the motor's actual start signature. After that, full-load trigger pulls clear without nuisance trips.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs that have sat unused can self-discharge below the charger's acceptance threshold — typically under 10V on a 12V pack — causing the charger to blink an error or do nothing at all. The fix is a recovery charge: some Skil chargers include a conditioning mode; if yours does not, a compatible Ni-MH charger with a trickle or reconditioning function can bring the pack back above the acceptance floor. Once cell voltage climbs above roughly 10.5V, the charger should recognise the pack and begin a normal charge cycle. Do not leave the pack on trickle for more than 12 hours.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416060723290,"sku":"BWCS-SHD736PW-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416060756058,"sku":"BWCS-SHD736PW-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416060788826,"sku":"BWCS-SHD736PW-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHD736PW-1.webp?v=1779760056","url":"https:\/\/batteryweb.com\/products\/skil-hd3736-replacement-battery-12v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
