It fits the B+B, F9, F1011\/S, FM 433, and related models in the Telenot industrial remote range. The OEM part number is 6N-270AA.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB+B, F9, F1011\/S, and FM 433 compatibility:\u003c\/strong\u003e\n    These models share the same 7.2V six-cell Ni-MH pack configuration, connector pinout, and charge management circuit. A single replacement cell fits all of them — no adapters, no wiring changes required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles and verified the protection circuit holds stable voltage during solenoid activation events. The BMS did not trip on normal relay inrush loads typical of Telenot remote operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStorage and idle charge for infrequent crane use:\u003c\/strong\u003e\n    If the remote sits unused for more than four weeks, charge the battery before returning it to service. Ni-MH cells self-discharge at roughly 1–2% per day at room temperature — a remote left dormant for two months may not hold enough voltage to complete a relay activation sequence.\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 current draw spikes sharply for a fraction of a second. If the battery is at storage voltage — not fully charged — that inrush can pull the cell voltage below the BMS cutoff threshold, dropping the remote mid-operation. This is not a faulty battery. It is a cell that has not been charged to working voltage before use. Charge the pack fully before the first activation. The 6N-270AA cell should reach 8.4–8.7V at full charge across all six cells in series.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low-battery warning immediately after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell ships at storage voltage — typically 60–70% of rated capacity — not at full charge. The Telenot remote reads this as a low-battery state and flags it immediately. This is normal behaviour, not a dead cell. Connect the remote to its charger and run a full charge cycle before use. Once the pack reaches operating voltage, the low-battery indicator clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360044777562,"sku":"BWCS-TLF900BL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360044810330,"sku":"BWCS-TLF900BL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360044843098,"sku":"BWCS-TLF900BL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TLF900BL-1.webp?v=1778610728","url":"https:\/\/batteryweb.com\/products\/telenot-bb-replacement-battery-72v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
