It replaces OEM part number 92931 and fits directly into the HD3736's battery bay. Voltage, connector, and terminal layout match the original pack.\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 chemistry with a specific terminal configuration and slide-in latch. This pack matches that voltage rail and connector — the BMS on the tool's motor driver will see the same signal envelope as the factory pack.\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 the HD3736 platform, including high-inrush drilling starts. The BMS held steady across cold and warm start conditions without nuisance tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load conditioning for the HD3736:\u003c\/strong\u003e\n    On first use, run the drill at half load — light driving, not drilling — for two cycles before applying maximum torque. This allows the tool's overcurrent protection to profile the inrush signature before heavy fastening starts.\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 the HD3736 motor-start inrush surge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger hard on a cold pack, the motor draws a spike of current in the first 50–100ms that can exceed the BMS overcurrent threshold. On Ni-MH packs that have been sitting discharged, internal resistance is elevated — this makes the voltage sag deeper and the current spike sharper. The BMS reads that as a fault and cuts the output. Letting the pack warm up to room temperature before heavy use keeps internal resistance low enough that the inrush spike stays within the BMS window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the HD3736 pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs self-discharge during storage — if a pack sits long enough, cell voltage can drop below the charger's acceptance threshold. The Skil charger checks for a minimum voltage before initiating the charge cycle; if it sees less than roughly 1.0V per cell, it may refuse to start or show a fault blink. To recover the pack, use a charger with a reconditioning or trickle-start mode that can push a low current at 100mA until cell voltage climbs above the acceptance floor. Once the pack reaches that threshold, normal fast charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416060624986,"sku":"BWCS-SHD736PX-1","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416060657754,"sku":"BWCS-SHD736PX-2","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416060690522,"sku":"BWCS-SHD736PX-3","price":116.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHD736PX-1.webp?v=1779760056","url":"https:\/\/batteryweb.com\/products\/skil-hd3736-replacement-battery-12v-3300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
