It replaces OEM part 3BN67202AA and also fits handsets identified by part numbers 3BN67200AA and 3BN67201AA. Voltage and connector match the original, so no modifications are needed to fit the battery in the handset.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLucent 500 DECT and Mobile 500 DECT compatibility:\u003c\/strong\u003e\n    These handsets share the same 3.7V single-cell Li-ion architecture and identical battery bay dimensions. The BMS in each handset communicates over the same two-contact interface, so one battery covers both variants without any wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on a Lucent 500 DECT handset. The BMS accepted the cell without a voltage-mismatch fault, and the handset returned to normal standby and call state throughout testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after fitting:\u003c\/strong\u003e\n    Li-ion cells ship at a partial state of charge. After inserting this battery, seat the handset in the base and allow a full uninterrupted charge cycle before use. The handset's charge indicator will confirm when the cycle is complete.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell doesn't always deliver its rated 650mAh on the first cycle. The BMS needs one or two full charge-discharge cycles to calibrate its state-of-charge tracking against the new cell. If talk time feels short in the first day of use, run the handset down to low-battery warning, then charge it fully without interruption. By the second or third cycle, the BMS reading and actual cell capacity align.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing with the base after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the original battery cuts all power to the handset's memory, and some DECT 500 units drop their base station pairing when this happens. The handset will show no line or registration error on the display. To re-pair, hold the registration button on the base station until the LED flashes, then initiate registration from the handset menu. Once registered, the handset returns to normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339895570522,"sku":"BWCS-NSV810CL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339895603290,"sku":"BWCS-NSV810CL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339895636058,"sku":"BWCS-NSV810CL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSV810CL-1.webp?v=1778366907","url":"https:\/\/batteryweb.com\/products\/alcatel-lucent-500-dect-replacement-battery-37v-650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
