It replaces OEM part number 1000060. When the original battery no longer holds a charge through a normal call, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEXP1240 and EXP1240H compatibility:\u003c\/strong\u003e\n    Both handsets share the same battery bay dimensions (53.20 × 34.00 × 5.70mm), connector pinout, and 3.7V charge acceptance. One battery covers both variants 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 EXP1240 hardware. The BMS handled the base station's charge termination signal correctly and did not trip a false full-charge cutoff at low state-of-charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Seat the handset in the base immediately after installing this battery and leave it for a full 16 hours before first use. Li-ion cells shipped in partial-charge storage state need one complete charge cycle to let the BMS calibrate its capacity register accurately.\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 the new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Li-ion cell arriving from storage is not at full capacity — the BMS has not yet mapped the cell's actual charge curve. The handset's fuel gauge reads the stored register, not the real cell state, so it reports a low percentage even after the first charge. Run two to three full charge and discharge cycles through normal use. By the third cycle the BMS register aligns with actual cell capacity and talk time stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses base station pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery from a DECT handset cuts all power to the registration memory on some Uniden models. The base station and handset lose their shared link key. To re-pair, press and hold the page or find button on the base for five seconds, then follow the handset's on-screen pairing prompt. Once registration completes, confirm the handset shows the base station name or line status at idle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339914903642,"sku":"BWCS-AY4020CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339914936410,"sku":"BWCS-AY4020CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339914969178,"sku":"BWCS-AY4020CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AY4020CL_1.webp?v=1778366906","url":"https:\/\/batteryweb.com\/products\/uniden-exp1240-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
