The 2536 AC handles screwdriving and pre-drilling in wood, and it needs a stable low-voltage cell to keep torque consistent through a full session. Capacity comes in at 10.73Wh — higher than the stock 1.3Ah unit.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFits 2536 AC and 2536AC:\u003c\/strong\u003e Both model references point to the same screwdriver body, voltage rail, and battery connector — one cell fits both.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage under load and released cleanly at the low-voltage cutoff without triggering a fault state.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge before use:\u003c\/strong\u003e With Li-ion cells at this capacity, run a full charge cycle before the first session — it lets the BMS calibrate the top and bottom thresholds accurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy capacity matters on a 3.6V screwdriver\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 2536 AC produces up to 7 Nm of torque at 185 rpm. That torque draw pulls hard on the cell, especially when driving into dense wood. A higher-capacity cell sustains voltage under that load longer before the BMS steps in to protect the chemistry. The stock 1.3Ah cell does the job at the bench — 2900mAh gives more headroom between charges on bigger tasks.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScrewdriver stalls mid-drive — what's happening and how to fix it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the 2536 AC cuts out partway through a fastener, the BMS has hit its low-voltage threshold under peak load — not a faulty battery. This happens most often with a deeply discharged or aging cell. Seat the battery fully, let it rest for two minutes, then retry. If it cuts out repeatedly from a full charge, the cell is no longer holding voltage under load and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175822721114,"sku":"BWCS-WGF300VX-1","price":22.08,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175822753882,"sku":"BWCS-WGF300VX-2","price":26.5,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175822786650,"sku":"BWCS-WGF300VX-3","price":29.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WGF300VX-1.webp?v=1775236276","url":"https:\/\/batteryweb.com\/products\/skil-2536-ac-replacement-battery-37v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
