It slots into the handset battery compartment and restores power to the handset when the original cell no longer holds a charge. Dimensions are 45.00 × 21.00 × 10.00mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDP 380FR, DP 411, DP 441, DPC 280 compatibility:\u003c\/strong\u003e\n    These four Lexibook handsets share the same 2.4V two-cell Ni-MH pack format and battery bay footprint. The voltage rail and connector orientation are identical across the group, so one battery part number covers all four models.\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 compatible Lexibook hardware. The base station accepted the charge handshake without error, and voltage held steady through multiple full cycles before reaching rated capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a Lexibook handset:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before the first call. Ni-MH cordless phone cells arrive partially discharged from storage — a slow, uninterrupted first charge lets the pack reach its rated 600mAh instead of forming at a lower ceiling.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping on the DP 380FR after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT transmit power draws in short, sharp bursts. When a fresh Ni-MH pack hasn't completed its first full conditioning cycle, internal resistance is higher than rated. Under RF load, voltage sags enough that the handset reduces transmit power to protect the circuit. The result looks like a range problem, but the battery is the cause. After three to five full charge-discharge cycles, internal resistance drops and the voltage holds steadier under load — range returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not coming on with a new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLexibook bases use a trickle-sense circuit that checks for a minimum voltage before committing to a charge cycle. A Ni-MH pack that has sat in storage can drop below that acceptance threshold — typically around 2.0V for a 2.4V pack. The base reads this as \"no battery present\" and shows no charge light. Remove the handset, wait 30 seconds, then reseat it firmly. If the light still doesn't appear, use a USB charger and a compatible cable to feed a brief top-up current into the pack directly, then return it to the base.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339990171738,"sku":"BWCS-BTB500CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339990204506,"sku":"BWCS-BTB500CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339990237274,"sku":"BWCS-BTB500CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTB500CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/lexibook-dp-380fr-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
