Mini \/ TH-EC Series — 12V Ni-MH Replacement Battery (BT923-00075)\u003c\/h2\u003e\n\n  \u003cp class=\"bpw-desc-lead\"\u003eThis is a 12V 2000mAh Ni-MH replacement battery for Cattron Theimeg crane and hoist remote controls. It fits the Easy u. Mini, TH-EC 30 u. 40, TH-EC\/LO, and Easy series handsets. Sourced to match the original BT923-00075 specification, including physical dimensions of 112.75 x 59.50 x 36.30mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-compatible across TH-EC and Easy platform remotes:\u003c\/strong\u003e\n    The Easy u. Mini, TH-EC 30 u. 40, and TH-EC\/LO all run the same 12V battery rail and share the same connector and bay dimensions. One cell covers all of them without adapters or modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and load discharge on TH-EC platform hardware. The BMS held stable through repeated solenoid-activation spikes, and cell balance remained within spec across five full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge during idle storage:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks between jobs. Ni-MH cells self-discharge at roughly 20–30% per month. Top up the charge every four weeks during idle periods or the cells will drop into a deep-discharge state that a standard charger may not recover.\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\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the remote triggers a crane solenoid or relay, the inrush current spikes sharply for 20–50 milliseconds. A battery at low state of charge cannot sustain the voltage through that spike, and the remote's processor resets mid-command. This looks like a lockout or freeze but it is a voltage-sag event. Always charge the battery fully before returning a remote to service after any swap or storage period. A fully charged 12V Ni-MH pack should read 13.2–14.4V immediately off the charger.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery warning immediately after a new cell is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship and store at approximately 50–60% state of charge, not full. The remote's voltage threshold reads this as a low-battery condition because it is one. This is not a faulty cell. Connect the battery to the original Cattron Theimeg charger and run a full charge cycle before powering the remote. A complete charge on a 2000mAh Ni-MH pack at standard 200mA charge rate takes roughly 12–15 hours — use the manufacturer charger, not a generic one, to avoid overcharge on Ni-MH chemistry.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360051265626,"sku":"BWCS-CBT923BL-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360051298394,"sku":"BWCS-CBT923BL-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360051331162,"sku":"BWCS-CBT923BL-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBT923BL-1.webp?v=1778610751","url":"https:\/\/batteryweb.com\/products\/cattron-theimeg-easy-u-mini-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
