It matches the original L30250-F600-C325 specification exactly, including cell chemistry and connector orientation. Capacity is sourced from product data — 900mAh \/ 3.33Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOpenstage WL3 and CUC325 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, connector pinout, and 3.7V charging rail from the base station. A single cell format covers both handsets 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 a controlled rig. The protection circuit tripped correctly at low-voltage cutoff and accepted a full charge from the base station cradle without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for the WL3 base station:\u003c\/strong\u003e\n    After fitting the new battery, seat the handset in the base cradle and leave it undisturbed for a full 16 hours before use. The WL3 base delivers a slow trickle charge — pulling the handset off the cradle early interrupts the cycle and the cell will not reach rated capacity on first use.\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 battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell does not always deliver full rated capacity on its first cycle. The electrochemical layers need two to three full charge-discharge cycles before the cell stabilises at 900mAh. If talk time feels short in the first week, run the handset down to the low-battery warning, then return it to the base for a full uninterrupted charge. By cycle three, capacity should be consistent.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing after removing the old battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Openstage WL3 stores its DECT pairing registration in volatile memory backed by the battery. When the old battery is fully discharged before removal, that registration is lost. Re-register the handset to the base by pressing and holding the pairing button on the base station until the LED flashes, then triggering the registration sequence from the handset menu under Settings. The handset should pair within 90 seconds.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339903271002,"sku":"BWCS-ASM620CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339903303770,"sku":"BWCS-ASM620CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339903336538,"sku":"BWCS-ASM620CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ASM620CL-1.webp?v=1778366906","url":"https:\/\/batteryweb.com\/products\/siemens-openstage-wl3-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
