It fits the handheld transmitter operators use to command crane movements on job sites. Voltage and chemistry match the OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCattron Theimeg transmitter fit:\u003c\/strong\u003e\n    The Theimeg platform runs a 12V Ni-MH pack with a specific cell count and connector arrangement. This battery matches that layout, including the BMS handshake the transmitter checks at power-on before enabling output.\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 and monitored voltage under inrush loads. The BMS held stable and did not trip during relay engagement spikes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge cycle during idle periods:\u003c\/strong\u003e\n    Ni-MH cells in crane remotes stored without use for weeks will self-discharge to a point where the transmitter shows low battery on first power-on. Charge the battery once a month during any idle period to prevent this.\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 a solenoid or relay fires inside the crane circuit, it draws a sharp inrush current that lasts milliseconds but spikes hard. A Ni-MH cell at partial charge has higher internal resistance, and that spike can pull the terminal voltage below the BMS cutoff threshold momentarily. The transmitter interprets this as a low-battery fault and cuts output. Fully charging the battery before first use drops internal resistance and keeps terminal voltage above the dropout point during activation events.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after putting in a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH battery ships at storage voltage — typically around 10.8–11V for a 12V pack — not at full charge. The Theimeg transmitter reads this as a depleted cell because it is below the operating threshold. This is not a faulty battery. Connect the battery to the charger for a full cycle first. Once it reaches 13.8–14.4V, the low-battery indicator clears and the remote operates normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360051462234,"sku":"BWCS-CBT923BX-1","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360051495002,"sku":"BWCS-CBT923BX-2","price":100.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360051527770,"sku":"BWCS-CBT923BX-3","price":111.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBT923BX-1.webp?v=1778610751","url":"https:\/\/batteryweb.com\/products\/jay-remote-cattron-theimeg-replacement-battery-12v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
