It replaces the original pack when the headset no longer holds charge through a normal call. At 30 x 20 x 4mm, it fits the ZX600 headset housing directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGigaset ZX600 fit:\u003c\/strong\u003e\n    The ZX600 headset runs a single lithium-polymer cell at 3.7V nominal. The cell dimensions and connector orientation are specific to this housing — no other Gigaset series shares this exact footprint.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the ZX600 base station and confirmed the BMS handshake completed correctly. The protection circuit responded to both charge termination and low-voltage cutoff without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the base station:\u003c\/strong\u003e\n    On first use, seat the headset in the base and let it complete a full charge cycle before taking a call. The base station logs the new cell during this cycle — until it does, the talk-time indicator will not read accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing full charge but headset cuts off early\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA replacement cell ships at storage voltage — typically around 3.6V — not at full charge. The base station can misread this as a charged pack before the first full cycle completes. When the headset then goes off-dock, actual usable capacity is far lower than the indicator suggests. Run one full uninterrupted charge in the base before first use to let the charging circuit calibrate to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than rated on the first few cycles\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells do not reach full rated capacity on cycle one. The ZX600 draws from both the audio circuit and the DECT radio simultaneously, which means any capacity shortfall shows up quickly. Over three to five full charge-discharge cycles, the cell reaches its rated 180mAh and talk time stabilises. If talk time is still short after five cycles, check that the base station charging contacts are clean and making firm contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428159455322,"sku":"BWCS-ZX6000SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428159488090,"sku":"BWCS-ZX6000SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428159520858,"sku":"BWCS-ZX6000SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZX6000SL_1.webp?v=1779934292","url":"https:\/\/batteryweb.com\/products\/siemens-gigaset-zx600-replacement-battery-37v-180mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
