It replaces OEM part numbers BP-T18, BP-T24, and P-P501. Capacity figure is taken directly from the product specification — 4.68Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e31001, 32001, and 32011 compatibility:\u003c\/strong\u003e\n    These three handsets share the same 3.6V three-cell Ni-MH pack format, connector pinout, and physical envelope. One battery fits all three because the charging circuit and BMS handshake are identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the BELL PHONE base charge cycle and confirmed the BMS accepted charge without error flags. Voltage climbed steadily from storage level to full charge without the delta-V cutoff triggering prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge conditioning for Ni-MH cordless packs:\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 ship partially discharged and need one slow, uninterrupted charge to reach their rated 1300mAh capacity — skipping this leaves the first few cycles noticeably short.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping on the 32001 and 32011 after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH voltage sags under the RF transmit load a DECT handset draws during a call. If the replacement pack hasn't been fully conditioned, its internal resistance is higher than a properly cycled cell — voltage drops further under load, and the handset's RF output backs off to compensate. The result is shorter range even though the handset shows a full battery icon. Three full charge-discharge cycles bring internal resistance down to spec and restore normal transmit headroom.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after fitting the new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eBELL PHONE bases use a voltage-sense threshold to confirm a battery is present before starting the charge cycle. A Ni-MH pack that has sat in storage drops to around 3.0V or below — some bases interpret this as a missing or faulty battery and refuse to initiate charge. Remove the handset, wait 10 seconds, and reseat it firmly. If the error persists, check that the handset contacts are clean and that the pack is pressing flat against the contact plate — a resting voltage of at least 3.2V is usually enough for the base to recognise the pack and begin charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340073697370,"sku":"BWCS-P501HL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340073730138,"sku":"BWCS-P501HL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340073762906,"sku":"BWCS-P501HL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P501HL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/bell-phone-31001-replacement-battery-36v-1300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
