It slots into the battery compartment on the back of the handset and restores normal operation when the original cell no longer holds a useful charge. Capacity and voltage match OEM specifications from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWL3 and WL3 Plus handsets:\u003c\/strong\u003e\n    Both models use the same battery bay, connector orientation, and 3.7V supply rail. A single cell 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 cell through charge and discharge on a DECT handset platform. The protection circuit responded correctly to overcharge and over-discharge events, and the cell reached rated capacity within the first three full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base cradle immediately after fitting this battery and leave it to charge uninterrupted for a full 16 hours before first use. Li-ion cells shipped in storage-mode benefit from one slow, complete charge to initialise the protection circuit at full capacity.\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 new Li-ion cell often delivers below-rated capacity in the first one to three cycles because the protection circuit calibrates itself against actual charge and discharge curves during early use. This is not a fault with the cell. Run two or three full charge-and-discharge cycles — use the handset until it prompts a low battery warning, then return it to the base for a complete charge. By cycle three, capacity stabilises at the rated 900mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing with base station after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery from a DECT handset cuts power completely, which can erase the pairing registration stored in volatile memory on some WL3 units. The handset and base need to re-register before calls work again. On the WL3, hold the paging button on the base for five seconds while the handset is powered on and within one metre of the base. The handset should display a registration prompt — follow the on-screen steps to complete pairing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339903434842,"sku":"BWCS-ASM620CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339903467610,"sku":"BWCS-ASM620CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339903500378,"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\/openstage-wl3-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
