Both devices draw from the same voltage rail and use the same physical footprint — 65.80 × 43.90 × 5.10mm — so one cell covers both. Capacity figures come from the product data, not inflated web listings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCDM530AM and MIFI H1 shared cell:\u003c\/strong\u003e\n    Both devices run the same 3.7V nominal rail and use an identical connector pinout. The BMS handshake matches on both platforms — no firmware rejection on pairing.\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 CDM530AM platform. The BMS held cutoff correctly at both ends — no premature low-voltage trip, no overcharge event at the top.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-charge cycle from 100% to near-empty and back. This lets the fuel gauge IC map its coulomb counter to the new cell's actual discharge curve before high-current charging pushes current into an uncalibrated register.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CDM530AM's fuel gauge IC holds a discharge curve learned from the original cell. When a new cell goes in, that stored curve no longer matches the real voltage drop profile. Under modem or screen load, the device hits a voltage cliff the gauge didn't predict and cuts power — even though the displayed percentage still reads 20–30%. Run one full uninterrupted discharge cycle to let the coulomb counter reset against the new cell. After that cycle, the gauge tracks correctly and shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after sitting in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored without charge self-discharge over weeks. If the cell drops below 2.5V, the BMS latches into lockout mode and blocks all current flow — the phone shows no response even on charge. Connect to a wall charger, not a USB port, and leave it for 20–30 minutes without touching it. A wall charger delivers enough trickle current to nudge the cell above the BMS recovery threshold, typically around 2.9V. Once the BMS releases, normal charging resumes and the phone powers on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409490673754,"sku":"BWCS-NK4LSL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409490706522,"sku":"BWCS-NK4LSL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409490739290,"sku":"BWCS-NK4LSL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK4LSL-1.webp?v=1778611065","url":"https:\/\/batteryweb.com\/products\/zalip-cdm530am-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
