It replaces the original cell pack when the handset can no longer hold a charge through a full call. Voltage and physical dimensions match the Univerge 120 battery bay: 58.12 × 45.30 × 15.60mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUniverge 120 handset fit:\u003c\/strong\u003e\n    The Univerge 120 uses a single 3.6V Ni-MH pack matched to the base station's charging circuit. Swapping chemistry or voltage would cause the base to misread charge state — this cell keeps the original voltage rail intact.\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 a Ni-MH-compatible test rig. The BMS accepted charge without thermal event, and cell voltage at full charge held at the expected 4.2–4.3V open circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells shipped in partial-discharge state need a slow initial charge to reach rated 1100mAh capacity — cutting it short locks in a lower usable ceiling.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charging error on a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries lose voltage during storage. If the cell drops below roughly 3.0V, some Univerge 120 base stations reject the charge cycle and flash an error light instead of beginning a charge. The base expects a minimum voltage before it opens the charge path. To recover, leave the pack seated in the base for 20–30 minutes — many chargers will trickle-feed a depleted cell back above the acceptance threshold before switching to full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells rarely deliver full rated capacity on the first cycle — this is normal, not a defect. Capacity builds across the first three to five full charge-discharge cycles as the crystal structure in the cells stabilises. Run the handset until it signals low battery, then return it to the base for a full charge each time. By cycle five, talk time should be at or close to the 1100mAh rated level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339997511770,"sku":"BWCS-BPX100CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339997544538,"sku":"BWCS-BPX100CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339997577306,"sku":"BWCS-BPX100CL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPX100CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/nec-univerge-120-replacement-battery-36v-1100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
