It fits the wireless handheld transmitter used to operate overhead cranes and industrial hoists. Sourced to match the original BT3613MH2 specification at 7.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWinner 2G Version 1 fit:\u003c\/strong\u003e\n    The Winner 2G Version 1 transmitter runs a single 3.6V Ni-MH cell pack. The BMS in this remote expects that voltage rail and cell chemistry — swapping to a different voltage or chemistry causes incorrect charge termination and unreliable shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Winner 2G Version 1 transmitter under load. The BMS accepted the cell, charged to full termination correctly, and held voltage steady through solenoid activation pulses without dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge during idle periods:\u003c\/strong\u003e\n    Crane remotes used infrequently are a common source of deep-discharge failure. If the Winner 2G sits unused for weeks, charge the battery once a month. Ni-MH cells left fully depleted for extended periods suffer capacity loss that no charger can reverse.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolenoid activation causing power dropout on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a crane remote triggers a solenoid or contactor relay, the inrush current spike can exceed what a low-capacity or partially charged pack can deliver cleanly. The transmitter BMS reads this as an overcurrent event and cuts output to protect the cell. The result looks like the remote died mid-command, even with a new battery installed. Charge the pack fully before use — a cell at storage voltage does not have the headroom to absorb that inrush spike without tripping the BMS.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after a fresh cell install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship and store at a reduced voltage — typically 1.0–1.1V per cell — not at full charge. The Winner 2G reads this as a depleted pack and flags low battery within seconds of power-on. This is not a faulty battery. Connect the remote to its charger for a full cycle before drawing any conclusions. The low-battery indicator should clear once the cell reaches its nominal 1.2V per cell charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360047431770,"sku":"BWCS-IBT615BL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360047464538,"sku":"BWCS-IBT615BL-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360047497306,"sku":"BWCS-IBT615BL-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IBT615BL-1.webp?v=1778610728","url":"https:\/\/batteryweb.com\/products\/itowa-winner-2g-version-1-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
