It replaces OEM part numbers UMB2 and BT7223. The OMNICONTROL system uses this cell to power the transmitter that operators use to position overhead crane loads from a safe distance.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOMNICONTROL and Wide Autonomy platform fit:\u003c\/strong\u003e\n    These remotes share the same 7.2V bus, connector housing, and BMS handshake across the OMNICONTROL, UME Wide Autonomy, OME Wide Autonomy, and OMR receiver-paired transmitter variants. One battery cell services all five listed configurations.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the OMNICONTROL transmitter platform. The BMS accepted the cell without fault flags, and solenoid-activation draw during crane command bursts stayed within the protection threshold throughout testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eIdle-period charge schedule:\u003c\/strong\u003e\n    Ni-MH cells self-discharge at roughly 1–2% per day. If this remote sits unused on a shelf for six or more weeks, charge it before putting it back into service — cells that drop below the BMS recovery floor will not respond to a charger at all.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the OMNICONTROL remote cuts out during solenoid activation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen an operator triggers a crane movement command, the transmitter drives a relay or solenoid output that creates a short inrush current spike. If the battery cell is partially discharged, internal resistance rises enough that this spike drags cell voltage below the BMS cutoff threshold momentarily. The BMS reads that as a fault and drops the output, killing the command mid-cycle. A fully charged, healthy cell keeps internal resistance low enough to absorb the inrush without triggering the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low-battery indicator immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA replacement Ni-MH cell ships at storage voltage — typically 1.1–1.2V per cell, which puts a 6-cell pack at roughly 6.6–7.2V, just at or below the transmitter's \"low battery\" threshold. The remote is not faulty and the cell is not defective. Connect the battery to its charger before first use and run a full charge cycle until the charger indicates complete. Voltage should read 8.4–8.5V at full charge before you install it in the transmitter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360052969562,"sku":"BWCS-IBT223BL-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360053002330,"sku":"BWCS-IBT223BL-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360053035098,"sku":"BWCS-IBT223BL-3","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IBT223BL-1.webp?v=1778610751","url":"https:\/\/batteryweb.com\/products\/jay-omnicontrol-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
