It matches the original RTE7220 specification exactly. If your crane or hoist remote is shutting down or no longer holding a charge, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAK2 Transmitter family fit:\u003c\/strong\u003e\n    The AK2, AK2 FW24, and AK2 FW43 all run the same 7.2V cell architecture and share the RTE7220 connector and BMS handshake profile. Swapping between variants in this series does not require a different battery.\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 an AK2 platform. The BMS accepted the cell without fault codes, and solenoid activation under load did not trigger a voltage dropout at full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge cycle during idle storage:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks between jobs. Ni-MH cells left discharged for extended periods develop voltage depression — charge this battery at least once a month during idle periods, even if the remote is not in use.\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  \u003cp class=\"bpw-desc-p\"\u003eWhen a solenoid or relay fires on a crane remote, it draws a sharp inrush current that lasts milliseconds but spikes well beyond normal operating draw. If the battery is not at full charge, terminal voltage can sag below the remote's cutoff threshold during that spike, causing the unit to shut down or reset. This is not a fault in the battery itself — it is a voltage headroom issue. Charge the RTE7220 fully before putting the remote back into service, and confirm resting voltage reads 8.4–8.6V off the charger before use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell ships at storage voltage, typically around 6.0–6.5V for a 7.2V pack — below the threshold the AK2 firmware uses to report adequate charge. The remote's battery indicator will show low or flash a warning even though the cell is not faulty. Connect the battery to the original Teletec charger and run a full charge cycle before powering on the remote. Once fully charged, resting voltage should read at least 8.4V and the warning will clear.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360054804570,"sku":"BWCS-TAK200BL-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360054837338,"sku":"BWCS-TAK200BL-2","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360054870106,"sku":"BWCS-TAK200BL-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TAK200BL-1.webp?v=1778610770","url":"https:\/\/batteryweb.com\/products\/teletec-10191556-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
