It slots into the handheld remote unit that lets users adjust audio without touching the main headset. Capacity figure is sourced from product data — 1.8Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlexcat and Flexmike compatibility:\u003c\/strong\u003e\n    Both units share the same 2.4V Ni-MH cell format, connector pinout, and BMS handshake requirements. Swapping the same pack across both platforms keeps the base station charge circuit happy without triggering a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the base station charge circuit and confirmed the BMS completed a full handshake. The cell accepted charge without a voltage spike at cut-off, and the base station cleared its charge indicator as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station protocol:\u003c\/strong\u003e\n    Seat the remote in the base station and let it complete one uninterrupted full charge before taking a call. DECT-based systems log the new cell's baseline capacity during that first cycle — skip it and the talk-time estimate will read inaccurately for several days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not recognising the new pack after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at a partial storage voltage — typically around 1.0–1.1V per cell. The Flexcat base station checks cell voltage on insertion before initiating a charge cycle. If the pack voltage is too low, the station can miss the handshake window and show no charge activity. Seat the remote firmly, leave it for 90 seconds, then remove and re-seat it. That brief contact allows the BMS to register and the base to start the charge sequence from the correct entry point.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cuts out mid-call after fitting a replacement pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe combined draw of the DECT radio and the audio circuit pulls more current than standby alone. A fresh Ni-MH cell that hasn't completed its first full conditioning cycle will show a voltage sag under that combined load — enough to trip the low-voltage cutoff and kill the connection. This isn't a faulty pack; it's an unconditioned cell. Run two or three full charge-discharge cycles through the base station before using the remote in an active call environment. After the third cycle the cell's internal resistance drops and voltage sag under load stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428095688794,"sku":"BWCS-LHA240SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428095721562,"sku":"BWCS-LHA240SL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428095754330,"sku":"BWCS-LHA240SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LHA240SL-1.webp?v=1779934085","url":"https:\/\/batteryweb.com\/products\/lightspeed-flexcat-handheld-remote-control-replacement-battery-24v-750mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
