It fits units that use OEM part numbers 3200, 38100, or 382001. When the original pack no longer holds a charge, this swap restores untethered operation within your base station's range.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNorthWestern Bell cordless handset fit:\u003c\/strong\u003e\n    These three OEM part numbers share the same 3.6V three-cell NiMH configuration, the same physical footprint (42.64 × 30.00 × 14.45 mm), and the same two-pin charge contact layout — which is why one pack covers all three references.\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 NiMH-compatible equipment. The cell voltage rose steadily to 4.3V at full charge across three conditioning cycles, and the BMS held within spec without tripping cutoff early.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before making any calls. NiMH cells in cordless phones need this slow initial charge to activate full capacity — skipping it will leave you with noticeably shorter talk time from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after a NiMH battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh NiMH pack sometimes causes range to drop shortly after a swap. The handset's RF transmitter draws a spike of current during each outgoing signal burst. If the battery hasn't been fully conditioned, internal resistance is still elevated and voltage sags under that RF load. The handset compensates by reducing transmit power, which cuts range. Complete three full charge-discharge cycles through normal use and the internal resistance will fall — range returns to normal after that.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after fitting the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries lose voltage during storage — if this pack sat in a warehouse for several months, its resting voltage may arrive below the threshold your base unit needs to detect a valid battery and begin charging. The base reads low voltage as an absent or faulty cell and either shows an error light or no charge indicator at all. Try jump-starting the process: connect the handset to a USB power bank via the charge contacts for 60–90 seconds to nudge the voltage above 3.2V, then seat it in the base immediately. The base should recognise it and begin the standard charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340107153498,"sku":"BWCS-CPB8013-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340107186266,"sku":"BWCS-CPB8013-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340107219034,"sku":"BWCS-CPB8013-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB8013-1.webp?v=1778367187","url":"https:\/\/batteryweb.com\/products\/northwestern-bell-replacement-battery-36v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
