It fits the wireless handset used to operate overhead cranes and industrial hoists. The OEM part number is BT3613MH2.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWinner 2G Version 2 fitment:\u003c\/strong\u003e\n    This battery shares the same voltage rail, connector footprint, and physical dimensions (61.40 × 49.50 × 22.30mm) as the factory cell. The remote's power circuit draws directly from a single 3.6V Ni-MH pack — no adapter or wiring change needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Winner 2G Version 2 handset and confirmed stable output across button activation cycles, including the inrush current spike that occurs when the remote signals a solenoid or relay command. The BMS held without dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge on crane remotes:\u003c\/strong\u003e\n    Ni-MH cells ship at partial storage voltage — typically 3.2–3.4V. Insert the battery and run a full charge cycle before taking the remote onto the crane floor. Attempting to operate at storage voltage shortens the usable charge cycle and may trigger low-battery warnings immediately after swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Winner 2G Version 2 drops power during solenoid activation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the remote transmits a crane movement command, the internal relay or solenoid driver draws a short inrush current spike that briefly loads the battery harder than idle transmission does. A partially discharged or degraded cell can't sustain voltage through that spike, and the remote's microcontroller resets or cuts out. This isn't a remote fault — it's a cell voltage problem. A fully charged 3.6V Ni-MH cell at 2000mAh handles these spikes without a dropout. If the issue persists on a fresh battery, check that the cell is fully charged before each shift.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because Ni-MH batteries leave storage at reduced voltage — around 3.2V — not at full charge. The Winner 2G Version 2 reads cell voltage on startup and flags anything below its threshold as low. The fix is straightforward: connect the battery to its charger for a full cycle before first use. Once the cell reaches its nominal 3.6V charge state, the low-battery indicator clears and the remote operates normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360046186586,"sku":"BWCS-IBT616BL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360046219354,"sku":"BWCS-IBT616BL-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360046252122,"sku":"BWCS-IBT616BL-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IBT616BL-1.webp?v=1778610728","url":"https:\/\/batteryweb.com\/products\/itowa-winner-2g-version-2-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
