It slots into the transmitter unit that operators use to send commands to overhead cranes and hoists on industrial sites. OEM part numbers BI2090B1 and 04.909 both apply to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCubix transmitter fit:\u003c\/strong\u003e\n    The Cubix platform runs a single-cell Ni-MH pack at 3.6V to power the transmitter's microcontroller, RF module, and button matrix. Voltage, connector orientation, and cell dimensions — 45.80 × 31.10 × 10.50mm — must match exactly or the housing won't close and the BMS won't handshake.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through transmitter wake-up, RF burst transmission, and solenoid-trigger sequences. The BMS held steady across repeated command bursts with no dropout or low-voltage cutoff events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH storage protocol for infrequent crane remotes:\u003c\/strong\u003e\n    If the Cubix remote sits unused for weeks between jobs, charge the battery once a month regardless. Ni-MH cells self-discharge at roughly 1–3% per day. A cell left flat in storage for months can drop below the transmitter's minimum operating voltage and fail to wake the unit at all.\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 Cubix transmitter fires a solenoid or relay command, the RF burst draws a short but sharp current spike. A cell sitting at storage voltage — typically around 1.2V nominal but partially depleted — can't sustain that inrush without the voltage rail sagging below the microcontroller's cutoff threshold. The transmitter then shuts off mid-command, which looks like a faulty battery even on a new cell. Charge the replacement fully before first use and confirm cell voltage reads at least 3.6V before reinstalling.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote shows low-battery warning immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at partial charge — typically 30–50% — to preserve cell health during transport. The Cubix transmitter reads this as a low state of charge and flags the warning straight away. This is not a faulty cell. Connect the remote to its charger for a full charge cycle before use. Once the cell reaches full charge, the low-battery indicator clears and the transmitter operates normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360070631514,"sku":"BWCS-FBA909BL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360070664282,"sku":"BWCS-FBA909BL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360070697050,"sku":"BWCS-FBA909BL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FBA909BL-1.webp?v=1778610751","url":"https:\/\/batteryweb.com\/products\/hbc-cubix-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
