It fits the Easy, Mini, TC100, and TC200 series transmitters. The BT923-00075 part number cross-references directly to the OEM unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEasy, Mini, TC100, TC200 platform fit:\u003c\/strong\u003e\n    These transmitters share the same 12V power rail, physical form factor, and connector pinout, which is why a single battery covers all four. The BMS handshake threshold is consistent across the range — no firmware variation to account for.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the TC100 transmitter platform. The BMS accepted charge immediately from a cold state, and the protection circuit tripped correctly at the low-voltage cutoff without latching the pack into lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH self-discharge on inactive remotes:\u003c\/strong\u003e\n    Ni-MH cells shed roughly 1–2% of charge per day at room temperature. A crane remote sitting unused for six weeks can drop to a voltage that prevents a clean startup. Charge the pack before any planned return-to-service, not after the remote fails to power on at the job site.\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 crane solenoid or relay fires, it draws a short inrush current spike that can exceed what a partially charged Ni-MH pack can deliver without voltage sagging below the transmitter's cutoff threshold. The remote resets mid-operation — not because the battery is faulty, but because it was not at full charge when the command was sent. Ni-MH packs at 70–80% state of charge still show a healthy resting voltage but collapse under transient load. Always bring the battery to a full charge before operating the crane — the resting open-circuit voltage should read 13.2V to 13.8V on a 10-cell 12V Ni-MH pack before use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery warning immediately after swapping in a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new or stored Ni-MH battery ships at around 40–60% of rated capacity — that is standard storage voltage, not a defect. The transmitter reads this as a low-battery condition because it is one. The fix is to connect the battery to the OEM charger and run a full charge cycle before installation. Once fully charged, the low battery indicator should clear within the first minute of operation as the transmitter samples voltage under light load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360051069018,"sku":"BWCS-CBT923BL-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360051101786,"sku":"BWCS-CBT923BL-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360051134554,"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\/laird-cattron-theimeg-easy-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
