It replaces OEM part BP1709\/A and restores power to handsets that no longer hold a charge. The cell measures 53.00 × 34.00 × 5.70mm — a direct physical match for the original battery compartment.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRove 30 and Rove 40 compatibility:\u003c\/strong\u003e\n    Both handsets share the same 3.7V single-cell Li-ion pack, connector pinout, and BMS handshake protocol — that is why one part number covers both models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the Rove 40 handset and confirmed the base station accepted the charging handshake immediately, with the BMS holding voltage steady across standby and active call load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base and leave it undisturbed for a full charge cycle before use — the Rove series base detects cell voltage and adjusts charge rate accordingly, so interrupting that first cycle can cause the base to underestimate capacity on subsequent charges.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected on the Rove 30 and Rove 40 after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells ship in a partial state of charge for transport safety. When the Rove base station first sees a new cell, it calibrates its fuel gauge against the incoming voltage — if that voltage is low, the gauge under-reports capacity and cuts off early. Running two or three full charge-and-use cycles resets the calibration. After that, the handset should reflect the full 1200mAh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRove handset loses DECT pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery from a Rove handset cuts all power to the DECT module, which can clear the stored base station registration in some firmware versions. The fix is straightforward: place the handset back in the base, press and hold the registration button on the base unit until the handset re-registers — the process takes under 60 seconds. If the handset still shows no link, confirm the battery is seated firmly and reading above 3.5V before attempting re-registration.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339909333082,"sku":"BWCS-TKA806CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339909365850,"sku":"BWCS-TKA806CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339909398618,"sku":"BWCS-TKA806CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TKA806CL-1.webp?v=1778366945","url":"https:\/\/batteryweb.com\/products\/poly-2200-86810-001-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
