It replaces OEM part numbers HBMAAF and HBL5AF. Fit the battery and the handset returns to normal operation on its existing base station.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF530 and FP515H series compatibility:\u003c\/strong\u003e\n    These handsets share the same battery bay dimensions, connector pinout, and 3.7V charging circuit. One battery covers all models in this group 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 the Huawei base station charge circuit. The BMS accepted the charge handshake without error, and voltage held steady at 3.7V nominal across full discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Li-ion cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full uninterrupted charge before making any calls. Huawei DECT handsets calibrate the fuel gauge on the first full charge cycle — interrupting it early can cause the battery indicator to misread capacity for several weeks.\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 F530 after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT transmit power on the F530 is voltage-dependent. When a partially charged or partially degraded cell sags below roughly 3.5V under RF load, the handset reduces transmit power to stay within safe operating limits. This looks like poor range but the handset is working correctly. A full charge cycle brings cell voltage back up and restores normal transmit power across the full coverage area.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing with base after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery from a Huawei DECT handset cuts all power to the pairing memory on some firmware versions. When power is restored with the new cell, the handset may not reconnect to the base automatically. To re-pair, hold the handset's page or locate button for 5–10 seconds while the base is powered on — this triggers a fresh DECT registration. Check your base station model's manual for the exact button sequence, but the fix is a standard re-registration, not a fault with the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339878629466,"sku":"BWCS-HUF530CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339878662234,"sku":"BWCS-HUF530CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339878695002,"sku":"BWCS-HUF530CL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUF530CL-1.webp?v=1778366843","url":"https:\/\/batteryweb.com\/products\/huawei-f530-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
