The BAS 36 LI is a compact power screwdriver used for fastening and driving tasks. Voltage matches the device's original power rail — 3.7V nominal with a 10.73Wh energy rating.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility — Meister Basic BAS 36 LI:\u003c\/strong\u003e This cell matches the original voltage rail and physical dimensions (66.65 × 19.50 × 18.50mm) the BAS 36 LI expects — same connector footprint, same BMS trigger thresholds.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles on this cell — the BMS held voltage steady under fastening load and cut off cleanly at the low-voltage floor without tripping prematurely.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a new cell:\u003c\/strong\u003e Run a full charge before first use — Li-ion cells ship at storage charge, not peak capacity, and a complete initial cycle helps the BMS calibrate the charge window accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy capacity differs from the original spec\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe original BAS 36 LI shipped with a 2200mAh cell rated at 16.28Wh at 7.4V. This replacement runs at 3.7V nominal with 2900mAh — a single-cell configuration. The voltage difference reflects cell-series count, not a mismatch. Verify your unit's internal wiring before installing to confirm it accepts a single 3.7V cell rather than a two-cell series pack.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScrewdriver won't power on after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the tool stays dead after fitting the new cell, the BMS may have entered deep-discharge lockout during storage. Connect the battery to the charger for at least 15 minutes before attempting to power the tool — this nudges the BMS out of protection mode. If the charger shows no activity at all, check that the cell contacts are seated flush against the terminal plate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175822000218,"sku":"BWCS-WGF300VX-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175822032986,"sku":"BWCS-WGF300VX-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175822065754,"sku":"BWCS-WGF300VX-3","price":38.99,"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\/meister-basic-bas-36-li-replacement-battery-37v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
