It slots into the C620 to restore cordless operation for IP-based conference calls and multi-participant meetings. Matches the OEM part number BT200660 and the original voltage and capacity spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC620 platform fit:\u003c\/strong\u003e\n    The C620 runs a 7.2V Ni-MH cell pack with a specific connector orientation and BMS handshake tied to the charging dock. This replacement matches that cell configuration, so the dock recognises the pack and initiates a normal charge cycle without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the C620's charge dock and confirmed the BMS accepted the battery, completed a full charge cycle, and reported correct charge status on the unit's display. No thermal events or charge rejections occurred during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-session calibration after swap:\u003c\/strong\u003e\n    After installing, run one complete charge cycle before your first meeting. The C620 maps battery state through normal charge and discharge — until that cycle completes, the on-screen indicator may report an inaccurate level. One full cycle corrects it.\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 wrong level after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe C620 uses a voltage-threshold method to estimate charge level. A new Ni-MH pack ships in partial discharge, so the unit has no calibrated reference point yet. The indicator reads whatever voltage it sees at startup and maps it to an approximate percentage — often too low or inconsistent. Dock the unit, let it charge fully to 8.64V (end-of-charge for a 7.2V Ni-MH pack), then discharge through a normal session before trusting the display.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eC620 not turning on after battery swap — dock shows no charging activity\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the pack sat in storage for an extended period, cell voltage can drop below the BMS re-initialisation threshold — typically under 6V for a 7.2V Ni-MH pack — and the dock's charge controller will refuse to begin a normal charge cycle. This is a deep-discharge lockout, not a failed battery. Place the unit in the dock and leave it for 30–60 minutes without pressing power; most C620 docks apply a low-current recovery charge below the cutoff threshold. Once cell voltage recovers above 6V, the dock switches to normal charge mode and the unit will power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339856347226,"sku":"BWCS-SMC620CL-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339856379994,"sku":"BWCS-SMC620CL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339856412762,"sku":"BWCS-SMC620CL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMC620CL-1.webp?v=1778366872","url":"https:\/\/batteryweb.com\/products\/snom-c620-sip-wireless-conference-replacement-battery-72v-3600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
