It replaces OEM part NTM\/BKBNB10114\/1. Fits the battery bay directly, using the same connector and cell footprint as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDT590 \/ DTX-9013 \/ DT5900 platform fit:\u003c\/strong\u003e\n    These three handsets share the same battery bay dimensions, connector pinout, and 3.7V supply rail. One cell SKU covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the DT590 platform. The protection circuit engaged correctly at low-voltage cutoff, and the base station accepted the charge handshake without error on first placement.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the DT590 base:\u003c\/strong\u003e\n    After installing this battery, seat the handset in the base and leave it for a full 16 hours before first use. Li-ion cells shipped in storage state need a complete slow charge to reach rated capacity — pulling the handset off early will leave you with a partially conditioned cell.\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 the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell arrives partially discharged from storage — typically between 40–60% state of charge. If you start using the handset immediately, the battery has not reached its rated 850mAh capacity yet. Complete two or three full charge cycles in the base before drawing conclusions about talk time. After the third full cycle, capacity should stabilise at or near the rated figure.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDT590 handset loses DECT pairing after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery cuts all power to the handset's volatile memory, which can erase the DECT registration stored in the handset. The base station will show the handset as unregistered or simply won't ring it. To fix this, re-register the handset through the base station's subscription mode — on most Ericsson DECT systems, hold the registration button on the base for three seconds, then follow the handset pairing prompt.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340051349594,"sku":"BWCS-ERT590CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340051382362,"sku":"BWCS-ERT590CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340051415130,"sku":"BWCS-ERT590CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERT590CL-1.webp?v=1778367046","url":"https:\/\/batteryweb.com\/products\/ericsson-dt590-replacement-battery-37v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
