It fits models cross-referenced under BBTY-0324001, BT-801, BT-810, BT-811, BT-815, and related variants. When the original pack stops holding a charge, this is the direct swap that restores the handset to working order.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBT-801 \/ BT-810 \/ BT-811 \/ BT-815 compatibility:\u003c\/strong\u003e\n    These models share the same 2.4V two-cell NiMH pack format, connector pinout, and physical footprint. The base station charges at a fixed current calibrated to this voltage range — swapping in the correct cell count matters more than brand markings.\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 Uniden handset base. The BMS accepted charge from the first session, and the protection circuit held stable at both the charge termination and low-voltage cutoff thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before making a call. NiMH cells in standby-use devices need a slow initial charge to condition the cells and reach rated 300mAh capacity — a short first charge will leave you well below that figure.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light on a fresh NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUniden base stations use a voltage-sense threshold to confirm a battery is present before starting the charge cycle. A new NiMH pack that has been sitting in storage can drop below that threshold — typically under 2.0V — and the base reads it as an absent or faulty cell. The fix is a brief top-up from a compatible external NiMH charger to bring the pack above 2.2V, after which the base will recognise it and begin normal charging. Once the base light comes on, leave the handset seated for the full 16-hour first charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells in low-drain cordless applications need three to five full charge-discharge cycles before they reach rated capacity. On the first cycle, 300mAh cells often deliver noticeably less — this is normal cell conditioning, not a defective pack. Each full cycle through the base charger builds capacity incrementally. By cycle four or five, talk time should stabilise at the level the 300mAh rating implies.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340072452186,"sku":"BWCS-BPT21CL-1","price":19.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340072484954,"sku":"BWCS-BPT21CL-2","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340072517722,"sku":"BWCS-BPT21CL-3","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPT21CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/uniden-bbty-0324001-replacement-battery-24v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
