It replaces the original pack when the handset no longer holds a charge or stops returning to full talk time. Fit the battery, seat the handset in the base, and let it complete a full charge cycle before use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSip Megaset 940 handset fit:\u003c\/strong\u003e\n    The Sip Megaset 940 runs a single-cell 3.6V Ni-MH pack with a fixed connector orientation matched by this replacement. The cell count, voltage rail, and physical dimensions — 52.99 x 44.48 x 15.15mm — align with the original bay without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the Sip Megaset 940 platform. The base station accepted the battery without error, and the BMS stepped through charge termination cleanly at rated voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\u003c\/strong\u003e\n    After installing, place the handset in the base for a full 16-hour charge before first use. NiMH cells in cordless phone packs do not reach rated capacity on a partial first charge — the slow initial cycle is what seats full capacity.\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 take three to five full charge-discharge cycles to reach rated capacity. On the first cycle, the Sip Megaset 940 handset will cut to low-battery alert earlier than expected — this is normal cell conditioning, not a fault. Each full cycle adds recoverable capacity until the pack stabilises around 1200mAh. Run the handset to low-battery alert, return it to the base for a full charge, and repeat for at least three cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no-charge or error light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA replacement NiMH pack stored in a warehouse can drop below the voltage threshold the Sip Megaset 940 base uses to confirm a valid battery is seated. When the base reads voltage below roughly 3.0V, it may show an error light or refuse to enter charge mode. Remove the handset, wait 10 seconds, and reseat it firmly — this resets the charge detection circuit. If the error persists, leave the handset seated for 30 minutes; the trickle pre-charge stage will lift cell voltage above the acceptance threshold and normal charging will begin.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340078645338,"sku":"BWCS-SIG920CL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340078678106,"sku":"BWCS-SIG920CL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340078710874,"sku":"BWCS-SIG920CL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SIG920CL_1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/telecom-sip-megaset-940-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
