These are portable business conference units used for wireless meeting calls. Install this pack to restore untethered operation when the original cell no longer holds a useful charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e55W and 55WX compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay, connector pinout, and BMS handshake protocol — one pack covers both. The voltage rail and physical form factor are identical across the two units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through a 55W unit and confirmed the BMS completed a full charge handshake, the fuel gauge updated correctly, and the unit powered on without triggering a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-session calibration tip:\u003c\/strong\u003e\n    After installing, run a complete charge cycle before your first meeting. The 55W maps battery state during normal operation, so the charge indicator may read inaccurately for one session until the system establishes a voltage baseline with the new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery indicator showing the wrong level after a pack swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 55W uses a voltage-threshold method to estimate charge level. A new pack from storage sits at a resting voltage the unit hasn't seen before, so the indicator often reads low or jumps erratically for the first session. This is not a fault in the battery. Run the unit through one full charge from flat to 100% and the indicator will recalibrate to the new cell's voltage curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eConference unit not turning on after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement packs stored in a warehouse can drop below the BMS low-voltage lockout threshold — typically under 2.5V per cell for a 3.7V Li-ion pack. When that happens, the unit receives no power and shows no response at all. Connect the unit to the original Konftel charger and leave it for at least 30 minutes before attempting to power on. Most BMS circuits will accept a trickle charge at this point and step up to normal charging once the cell recovers above the lockout floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339864178778,"sku":"BWCS-KFL300CL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339864211546,"sku":"BWCS-KFL300CL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339864244314,"sku":"BWCS-KFL300CL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KFL300CL-1.webp?v=1778366872","url":"https:\/\/batteryweb.com\/products\/konftel-55w-conference-phone-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
