It slots into the handset battery compartment and restores wireless operation when the original cell has lost capacity or stopped holding a charge. Voltage and cell format match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGigaset E40 \/ E45 \/ E450 platform fit:\u003c\/strong\u003e\n    These handsets share the same battery bay dimensions (35.60 × 31.80 × 6.60mm), 2.4V two-cell NiMH configuration, and charging contact layout — so one battery cell serves the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a Gigaset base station. The BMS accepted the cell without error, charge termination triggered correctly at full voltage, and the handset registered a full charge indicator on the display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    Place the handset in the base immediately after fitting and leave it for a full 16 hours before first use. NiMH cells shipped in storage state do not reach rated capacity on a short top-up charge — the slow first charge is what conditions the cell to its full 500mAh.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Gigaset E450 base station shows a charging error on a new NiMH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gigaset base station uses a delta-V detection circuit to confirm that a NiMH cell is accepting charge. A battery shipped in deep storage can sit below 2.0V total, which some base stations interpret as a fault rather than a dischargeable cell. The fix is to place the handset in the base and leave it — the trickle pre-charge stage will bring the cell voltage up to the acceptance threshold within 30 to 60 minutes, after which normal fast charge begins and the error light clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells do not deliver full rated capacity from cycle one — this is normal chemistry behaviour, not a fault with the replacement. The cell needs three to five full charge-discharge cycles before the crystalline structure in the electrodes stabilises and the cell reaches its rated 500mAh. Each full cycle closes the gap. To run a proper conditioning cycle, use the handset until the low-battery indicator appears, then return it to the base for a full uninterrupted charge before using it again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340055543898,"sku":"BWCS-SX382CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340055576666,"sku":"BWCS-SX382CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340055609434,"sku":"BWCS-SX382CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SX382CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/siemens-gigaset-e40-replacement-battery-24v-500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
