It replaces the original pack that powers the handset away from the base station. When the original battery no longer holds charge, this direct replacement restores normal cordless operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGigaset 140 handset fit:\u003c\/strong\u003e\n    The Gigaset 140 uses a fixed 2.4V two-cell Ni-MH pack with a specific connector and physical footprint. This battery matches that cell count, voltage, and form factor — the base station charging circuit expects exactly 2.4V nominal from a Ni-MH pack, so chemistry and voltage both matter here.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Gigaset 140 base station charging circuit. The BMS accepted the charge without error, current tapered correctly at full capacity, and the handset registered a full battery indicator on the display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a new Ni-MH pack:\u003c\/strong\u003e\n    Place the handset in the base immediately after installing and leave it for a full 16 hours before first use. Ni-MH cells shipped from storage are partially discharged, and a slow first charge allows the cells to reach rated capacity properly — skipping this step causes short talk time in early cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping on the Gigaset 140 after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gigaset 140 transmit circuit draws a short burst of current each time the handset communicates with the base station. A Ni-MH pack that hasn't been conditioned yet shows a voltage sag under that RF load — the pack voltage dips, the transmit power drops, and range shrinks noticeably. This isn't a fault with the battery or the handset. After three to five full charge and discharge cycles, the cells build internal capacity and voltage sag under RF load decreases. Run three normal cycles and retest range before drawing any conclusions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating with new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs stored before sale drop to a low resting voltage — sometimes below the threshold the Gigaset 140 base uses to detect a valid battery and start charging. The base station reads the pack voltage on contact and won't initiate a charge cycle if it sees a voltage it doesn't recognise as a healthy Ni-MH cell. Remove the handset, wait 10 seconds, and reseat it firmly — good contact often triggers the detection circuit. If the charge light still doesn't activate, check that the handset contacts and base cradle contacts are clean and making solid connection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340063998042,"sku":"BWCS-SIG140CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340064030810,"sku":"BWCS-SIG140CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340064063578,"sku":"BWCS-SIG140CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SIG140CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/siemens-gigaset-140-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
