It fits the Gigaset A120, A140, A145, A140 Trio, and over 30 additional handset models that share the same cell format and connector. Voltage and capacity match the original Siemens specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGigaset A-series handset compatibility:\u003c\/strong\u003e\n    These models share the same 2.4V dual-cell NiMH pack, connector pin-out, and physical footprint — the A120 through A145 range all draw from the same battery platform, so one SKU covers the full family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on Gigaset A-series hardware. The BMS handshake completed correctly each cycle and the handset returned to standby without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it on charge for a full 16 hours before first use. NiMH cells in cordless phones need this slow initial charge to reach rated capacity — skipping it will result in noticeably shorter talk time on early cycles.\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 original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells ship in a partially discharged state and need three to five full charge-discharge cycles before they reach rated capacity. The Gigaset base station uses a trickle-charge circuit — it will not fast-condition a new pack. Run the handset until the low-battery indicator shows, then return it to the base for a full charge, and repeat this two or three more times before judging actual talk time.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eGigaset base stations check incoming voltage before committing to a charge cycle. A NiMH pack that has sat in storage drops below the threshold the base expects, and the charger circuit stalls or flags an error rather than charging. Remove the battery, short the terminals briefly with a resistor or a low-current load to bring the resting voltage above 2.0V, then reinstall and seat the handset firmly in the base. The charge indicator should activate within 30 seconds once the pack voltage clears that threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340055150682,"sku":"BWCS-SX383CL-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340055183450,"sku":"BWCS-SX383CL-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340055216218,"sku":"BWCS-SX383CL-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SX383CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/siemens-gigaset-a120-replacement-battery-24v-650mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
