It slots into the handset battery compartment using the same form factor as the stock cell — 61.90 x 38.00 x 14.20mm. When the original no longer holds a charge through a full business day, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e6020 \/ 6030 \/ 8020 \/ 8030 platform fit:\u003c\/strong\u003e\n    These models share the same handset body, battery bay dimensions, and 3.7V single-cell architecture. One battery pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a Polycom handset and confirmed the BMS accepted full charge from the base station without triggering a fault state or charging cutoff error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Li-ion handsets:\u003c\/strong\u003e\n    After fitting this battery, seat the handset in the base and leave it on charge for a full cycle before taking it off-hook. Li-ion cells shipped in storage state need one complete charge pass to calibrate the handset's charge indicator accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Li-ion cell shipped from storage arrives at a partial state of charge — typically 30–50%. The handset's fuel gauge reads this as a calibrated baseline, which compresses the apparent capacity. Run two full charge-and-discharge cycles through normal use and the handset will recalibrate its gauge against the full 1800mAh. After the second cycle, talk time should match rated capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses DECT pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the battery cuts all power to the handset, which can wipe the stored base station pairing on some Polycom DECT models. The handset boots without a registered base and shows no line or signal. To fix this, initiate a fresh registration from the handset menu — on the 6020 and 8020, this is under Settings \u0026gt; Register Handset — then enter the base PIN (default: 0000).\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339933024346,"sku":"BWCS-BPL100CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339933057114,"sku":"BWCS-BPL100CL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339933089882,"sku":"BWCS-BPL100CL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPL100CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/polycom-6020-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
