It fits the handheld transmitter unit used to operate overhead cranes and industrial hoists. Voltage and cell chemistry match the OEM specification for the BT 923-00075 battery.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCattron Theimeg transmitter fit:\u003c\/strong\u003e\n    These remotes run a 12V Ni-MH pack because the solenoid-driven relay logic inside the transmitter needs stable current during button press events. A mismatched voltage or chemistry causes erratic command output or no response from the crane controller.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated solenoid-activation loads and confirmed the BMS held output voltage steady. No dropout occurred during high-current button-press bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge protocol for crane remotes:\u003c\/strong\u003e\n    Batteries shipped in storage state sit at approximately 9–10V. Connect to the Cattron charger for a full cycle before putting the remote into service — Ni-MH cells at storage voltage will report low battery within minutes of first use and may not recover full capacity without that initial conditioning charge.\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  \u003cp class=\"bpw-desc-p\"\u003eWhen an operator presses a crane control button, the transmitter briefly pulls a sharp current spike to fire the internal relay or solenoid. If the battery is partially discharged or not fully conditioned, internal resistance is high enough that this inrush current drags the terminal voltage below the BMS cutoff threshold. The remote cuts out mid-command — the crane stops responding even though the battery indicator showed capacity. A full charge cycle before first use and after any extended idle period reduces internal resistance and keeps terminal voltage above the 10.5V cutoff during activation events.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH pack ships at storage voltage — typically 9.6–10V across a 12V nominal pack — not at full charge. The Cattron Theimeg transmitter reads this low resting voltage and flags a low-battery warning within the first few minutes of use. This is not a faulty battery. Connect the battery to the OEM Cattron charger and run a complete charge cycle until the charger indicates full — resting voltage should reach 13.2–14.4V before the battery goes into service.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360051167322,"sku":"BWCS-CBT923BL-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360051200090,"sku":"BWCS-CBT923BL-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360051232858,"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\/jay-remote-cattron-theimeg-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
