It restores power to the wireless remote used to operate overhead cranes and lifting equipment. Swap it in when the original cell can no longer hold charge or fails to power the remote at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTY 55.00.56 remote compatibility:\u003c\/strong\u003e\n    The HR3AA cell matches the voltage rail and physical footprint of the OEM battery in this Tyro remote. The connector orientation and BMS handshake remain consistent with the factory specification, so no modification is needed on installation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the bench. The BMS held charge acceptance stable across multiple cycles, and the cell reached rated capacity without thermal anomalies or cutoff trips during normal remote operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStorage charge for infrequently used remotes:\u003c\/strong\u003e\n    Crane remotes often sit idle between jobs for weeks or months. If the HR3AA drops below its low-voltage floor during extended storage, the protection circuit can lock out and refuse a standard charge. Run a top-up charge once a month during any idle period to keep the cell above that threshold.\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 freshly installed battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the crane remote triggers a solenoid or relay, the inrush current spike can briefly exceed what a low-capacity or partially charged cell can supply. The BMS interprets this as an overload condition and trips the output, cutting power to the remote mid-command. This is not a fault with the remote itself — it is a current-delivery issue. Ensure the HR3AA is fully charged before use; a cell at storage voltage (typically around 1.2V nominal) will not deliver the peak current that solenoid activation demands.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell ships at storage voltage, not full charge. If the remote reads low battery the moment you install it, the cell simply has not been charged yet. Connect the remote or cell to its charger before attempting to use it. After a full charge cycle, the remote's battery indicator should clear. If it does not, check that the cell is seated correctly and the contacts are making clean connection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360059031642,"sku":"BWCS-TRY056BL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360059064410,"sku":"BWCS-TRY056BL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360059097178,"sku":"BWCS-TRY056BL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRY056BL-1.webp?v=1778610769","url":"https:\/\/batteryweb.com\/products\/tyro-ty-550056-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
