These pendants are used by crane operators to command hoist and travel functions on the job site. It also cross-references OEM part numbers BAT-0000327 and 250806.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExcalibur and CT24-UB compatibility:\u003c\/strong\u003e\n    Both remotes run on the same 3.6V single-cell Ni-MH platform with the same connector footprint and BMS handshake requirements. One replacement covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through repeated solenoid activation sequences on the bench. The BMS held stable under the inrush current spikes typical of relay and solenoid engagement — no mid-operation dropout observed across the test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStorage voltage for infrequently used crane remotes:\u003c\/strong\u003e\n    If a pendant sits unused for more than 30 days, charge it before returning it to service. Ni-MH cells self-discharge faster than Li-ion — a pendant left dormant for two to three months can drop low enough that the remote shows a low-battery alert immediately on startup, even with a fresh cell installed.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePower dropout during solenoid or relay activation on the Excalibur\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the Excalibur triggers a crane movement, the solenoid or relay draws a sharp inrush current for a fraction of a second. A degraded or deeply discharged cell cannot sustain voltage under that load spike, causing the remote to cut out momentarily or reset. This is not a transmitter fault — it is the cell voltage collapsing below the BMS cutoff threshold during peak draw. Fitting a fully charged 2000mAh cell resolves this; if dropout continues, confirm the cell is at or above 4.0V total terminal voltage before use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote shows low battery immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship and store at a reduced voltage — typically 30–50% of full charge — to slow self-discharge during transit. When the Excalibur reads terminal voltage on startup, a cell at storage voltage registers as low and triggers the indicator before any real use occurs. This is not a faulty cell. Connect the pendant to its charger and run a full charge cycle before first use; the low-battery alert will clear once the cell reaches operating voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360049922138,"sku":"BWCS-CBT116BL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360049954906,"sku":"BWCS-CBT116BL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360049987674,"sku":"BWCS-CBT116BL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBT116BL-1.webp?v=1778610709","url":"https:\/\/batteryweb.com\/products\/cattron-theimeg-excalibur-remote-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
