It fits the portable handset unit that pairs with the Telrad 3040 corded base station. Dimensions are 51.54 x 32.75 x 8.30mm — confirm against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTelrad 3040 handset fit:\u003c\/strong\u003e\n    This battery matches the voltage rail and physical footprint the 3040 handset expects. The 3.7V output keeps the DECT radio and talk circuit within operating range without triggering the handset's low-voltage cutoff during normal use.\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 bench. The protection circuit held charge termination correctly and the BMS responded to draw without tripping prematurely under simulated DECT transmit load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the Telrad 3040 base:\u003c\/strong\u003e\n    After installing, 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 first charge cycle to register correctly with the handset's charge management circuit.\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 arrives partially discharged from storage. If you pull the handset off the base after only a short charge, the cell hasn't reached full capacity yet. The handset's fuel gauge may also show inaccurate readings until the battery completes one full charge cycle. Run it flat, charge it fully in the base, and capacity will settle to the rated 950mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses DECT pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the old battery cuts power completely to the handset's memory. Some DECT phones store their pairing registration in volatile memory, and that data clears when the battery is disconnected. After fitting the new battery, the handset may show \"unregistered\" or fail to connect to the base. Re-register the handset using the base station's registration button — on the Telrad 3040, 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":43339919720538,"sku":"BWCS-CIP502CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339919753306,"sku":"BWCS-CIP502CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339919786074,"sku":"BWCS-CIP502CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CIP502CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/telrad-3040-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
