It uses OEM part number BL7.2 and matches the original voltage and connector layout. Capacity is 19.24Wh — drawn from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRC 012 \/ RC12 platform compatibility:\u003c\/strong\u003e\n    These models share the same 7.4V battery bay, connector pinout, and BMS communication protocol. The RC12R and RC12RI add a receiver module but draw from the same power rail, so the same battery fits all four without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a crane remote test rig. The BMS correctly flagged over-discharge at the 2.5V per-cell threshold and held the protection latch until reconnected to a charger — expected behaviour for this platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eInfrequent-use charging protocol:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks between lifts. If the remote will be idle for more than three weeks, connect the charger for a top-up cycle before storage — Li-ion cells left below 2.5V per cell trigger BMS deep-discharge lockout that a standard charger cannot always reverse.\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 an operator triggers a crane function, the solenoid or relay draws a sharp inrush current spike — sometimes 3–5× the steady-state draw. If the battery cell is at storage voltage (around 3.7V per cell) rather than full charge, the voltage sag during that spike can drop below the BMS cutoff threshold. The BMS interprets this as an undervoltage fault and disconnects the output rail. The remote goes dark mid-command. Charge the battery fully to 8.4V before the first lift — this gives the cells headroom to absorb the inrush without triggering a protection trip.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote shows low-battery warning immediately after swapping the cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.7–3.8V per cell, or roughly 7.4–7.6V total. The RC 012 firmware reads resting voltage at power-on and maps it to a charge percentage. At storage voltage, that reading lands in the low-battery zone, so the warning triggers right away even though the battery is not depleted. This is not a faulty cell. Connect the battery to the charger until it reaches 8.4V, then power the remote on — the warning will clear and the voltage reading will reflect actual charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360068075610,"sku":"BWCS-FRC230BL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360068108378,"sku":"BWCS-FRC230BL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360068141146,"sku":"BWCS-FRC230BL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FRC230BL-1.webp?v=1778610750","url":"https:\/\/batteryweb.com\/products\/falard-rc-012-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
