It replaces the original handset cell when charge no longer holds between calls. Dimensions are 48.46 x 31.16 x 10.67mm — confirm against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared platform across 1231–2420 models:\u003c\/strong\u003e\n    These Lucent handsets run the same 3.6V single-cell NiMH architecture with a matching connector and form factor, which is why one battery covers the full model range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on compatible Lucent handsets and confirmed the BMS in the base station accepts the pack without flagging a charge error or refusing to initiate the charge sequence.\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 first use. NiMH cells ship at partial charge — skipping this slow initial charge will reduce usable capacity and the battery will not reach its rated 700mAh.\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 original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew NiMH cells do not deliver rated capacity on the first cycle. The cell chemistry needs three to five full charge-discharge cycles before the plates are fully activated and capacity stabilises near 700mAh. During this conditioning period, talk time will be noticeably shorter than expected — this is normal behaviour, not a fault with the battery. Run the handset until it drops to low-battery alert, then return it to the base for a full charge, and repeat for at least three cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLucent bases use a voltage threshold to detect whether a valid NiMH pack is seated — if the battery voltage is too low from extended storage, the base may not recognise it and will show no charge activity or an error indicator. This is a BMS acceptance issue, not a faulty battery. Place the handset in the base and wait 30 minutes; some bases will begin a trickle pre-charge once they detect minimal cell voltage. If the base still shows no activity after 30 minutes, reseat the handset firmly and check that the charging contacts on both handset and base are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340020088922,"sku":"BWCS-CPB1024-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340020121690,"sku":"BWCS-CPB1024-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340020154458,"sku":"BWCS-CPB1024-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB1024-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/lucent-1231-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
