It fits the 255, 4200, 32500, and 32001 models, along with one additional compatible handset. The battery slots into the handset compartment and restores cordless operation when the original pack no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across the NorthWestern Bell cordless range:\u003c\/strong\u003e\n    These handsets share the same 3.6V single-cell NiMH pack format, connector orientation, and charging circuit. One battery covers the full group 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 a NiMH-compatible cordless phone base. The BMS accepted charge from the base station without triggering an error state, and cell voltage held steady at 3.6V nominal across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    After fitting this battery, seat the handset in the base and leave it for a full 16 hours before use. NiMH cells in cordless phones need a slow initial charge to reach rated capacity — a short top-up charge will leave the pack underperforming for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy talk time stays short for the first few cycles after a NiMH swap\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. On cycle one, you may see noticeably shorter talk time — this is the chemistry settling, not a fault with the cell. Each subsequent full cycle pushes the usable capacity closer to the rated 700mAh. Run the handset until the low-battery alert sounds, return it to the base for a full charge, and repeat — capacity improves with each pass.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge or error light after fitting the new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells stored at low voltage can read below the base station's charge acceptance threshold, causing the base to skip the charge cycle or display an error. This happens when the pack voltage drops under roughly 3.0V during storage. To recover it, remove the handset, wait 30 seconds, reseat it firmly in the base, and confirm the charge indicator activates. If the error persists, the pack may need a brief external boost charge to bring it above the 3.0V threshold before the base will accept it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340083593306,"sku":"BWCS-P501CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340083626074,"sku":"BWCS-P501CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340083658842,"sku":"BWCS-P501CL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P501CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/northwestern-bell-255-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
