It replaces OEM part numbers BT-800 and BT-905. When the original pack stops holding a charge, this battery restores normal handset operation without replacing the whole phone system.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad handset compatibility:\u003c\/strong\u003e\n    These Uniden models share the same 3.6V NiMH cell configuration, connector pinout, and charge-acceptance voltage range — so one battery pack covers over 160 handset variants 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 Uniden handset cradle. The BMS accepted charge correctly at the base station voltage and held stable output across the RF transmit load without dropping below the handset's low-battery cutoff threshold.\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 use. NiMH cordless phone batteries do not reach rated capacity on a short first charge — skipping this step is the most common reason a new battery appears weak out of the box.\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 battery swap on Uniden cordless handsets\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells that haven't been conditioned yet show a lower resting voltage than a fully cycled pack. When the handset's RF transmitter pulls current during a call, that low voltage sags further — and the handset responds by reducing transmit power to stay within operating limits. The result looks like a range problem, but it's actually a voltage problem. Run three to five full charge-and-discharge cycles through the base station and the transmit power will stabilise at its normal level.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light or error after installing a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries discharged below approximately 3.0V during storage can fall outside the voltage window the base station uses to detect a valid battery. The charger circuit sees a voltage it doesn't recognise and either shows an error or does nothing. To recover, leave the handset seated in the base undisturbed for at least 30 minutes — most Uniden base stations apply a trickle current that slowly raises cell voltage until the charge circuit takes over. If the charge light comes on after that window, the pack is recovering normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340074451034,"sku":"BWCS-P501HL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340074483802,"sku":"BWCS-P501HL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340074516570,"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\/uniden-24-148-replacement-battery-36v-1300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
