It replaces OEM part CB50-BATT. The CB-50 runs its DECT radio and audio circuits off this single cell pack, so a degraded battery affects both transmission range and call clarity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCB-50 compatibility:\u003c\/strong\u003e\n    The CB-50 uses a 2.4V Ni-MH cell at this exact form factor — 44.50 × 20.50 × 10.50mm. The base station charges and monitors this pack directly. Voltage, connector, and physical dimensions must match for the base to accept the battery and report charge status correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the CB-50 base station and confirmed the BMS handshake completed cleanly — the charge indicator moved through its normal stages without error flags. The cell reached full charge voltage without thermal irregularities in the housing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst cycle on the CB-50 base station:\u003c\/strong\u003e\n    Seat the new battery in the CB-50 headset and place it on the base station before making any calls. The base needs to complete one full charge cycle to register the new cell and calibrate the talk-time indicator. Taking a call before this cycle finishes will produce inaccurate charge readings.\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\"\u003eThe CB-50 base station performs a low-level handshake when a battery is seated — it checks cell voltage before initiating the charge cycle. A new Ni-MH pack shipped at storage voltage can sit below the threshold the base expects, causing the charge light to blink an error or show no activity at all. This is not a faulty battery. Leave the headset seated in the base for 30 to 60 minutes — the base will trickle charge the cell to a level where the main charge cycle kicks in. Once the normal charge indicator appears, the handshake has completed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCB-50 headset cuts out mid-call despite a full charge indicator\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMid-call cutouts on the CB-50 usually point to voltage sag under combined load — the DECT radio and audio amplifier draw current simultaneously, and a cell that hasn't completed its first full cycle can't sustain voltage under that combined pull. The BMS interprets the sag as a low-cell event and shuts the headset down as a protection measure. Run two or three complete charge-and-use cycles through the base station first. By the third cycle, the Ni-MH cell reaches stable capacity and holds voltage above the BMS cutoff threshold during active calls.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428138549338,"sku":"BWCS-TCB500SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428138582106,"sku":"BWCS-TCB500SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428138614874,"sku":"BWCS-TCB500SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TCB500SL-1.webp?v=1779934245","url":"https:\/\/batteryweb.com\/products\/chatterbox-cb-50-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
