It replaces OEM part GP230AAHC6YMXZ directly. The C52-SP is a wireless conference speakerphone, and this battery is what keeps it untethered during meetings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC52-SP platform fit:\u003c\/strong\u003e\n    The C52-SP runs a 7.2V Ni-MH pack to handle combined DECT radio and audio amplifier draw simultaneously. This replacement matches that voltage rail and cell arrangement, so the BMS reads state-of-charge correctly from the first session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under a combined wireless-plus-audio load profile that mirrors a live conference call. The BMS held stable across the draw curve without triggering a low-voltage cutoff early.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-session calibration tip:\u003c\/strong\u003e\n    After installing, run one full charge before the first meeting. The C52-SP maps battery state during normal operation, and without that initial full charge, the onboard indicator may flag a false low-battery warning mid-session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage sag under combined DECT and audio draw in the C52-SP\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe C52-SP pulls current from two systems at once — the DECT radio module and the speaker amplifier. A degraded or deeply discharged pack cannot sustain the combined draw, and voltage drops below the BMS threshold during active calls. This triggers a protective cutoff that looks like a sudden power failure mid-meeting. A fresh pack at full charge holds the voltage rail above the 6.0V cutoff point where the BMS would otherwise intervene.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery indicator showing wrong charge level after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe C52-SP estimates charge level by tracking voltage thresholds, not a fuel gauge IC. A new pack comes off storage at a partial state of charge, so the unit has no reference point yet. This causes the indicator to show an inaccurate level — sometimes too high, sometimes too low — for the first session. Run one complete charge cycle to the dock's charge-complete signal, then discharge through normal use, and the indicator will read correctly from the next session onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339859427418,"sku":"BWCS-SMC520CL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339859460186,"sku":"BWCS-SMC520CL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339859492954,"sku":"BWCS-SMC520CL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMC520CL-1.webp?v=1778366873","url":"https:\/\/batteryweb.com\/products\/snom-c52-sp-dect-expansion-speakerphone-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
