It replaces OEM part BAT16484000 directly. Fit the replacement when the original cell shows capacity fade, unexpected shutdowns, or fails to hold charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX5 Max Pro cell fit:\u003c\/strong\u003e The BAT16484000 uses a specific contact layout and dimensions (79.84 × 55.45 × 5.85mm) tied to the X5 Max Pro chassis. The BMS handshake on this device is straightforward — no encrypted authentication chip — so the replacement cell communicates correctly with the charge IC without additional pairing steps.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We cycled this cell through full charge and discharge on the X5 Max Pro platform. The BMS accepted the cell on first connection, charge termination triggered correctly at 4.2V, and cutoff activated cleanly at the low-voltage threshold without false triggers.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e After fitting this cell, disable fast charging if available and run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC one complete cycle to map the new cell's discharge curve before reporting accurate percentages.\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 X5 Max Pro after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe X5 Max Pro's fuel gauge IC stores a charge curve calibrated to the original cell. A new cell has a different internal resistance profile, so the IC misjudges remaining capacity. Under load — particularly when the modem transmits or the screen peaks — the new cell's voltage drops faster than the IC expects, triggering a low-voltage shutdown well above 0%. One full discharge-charge cycle corrects the stored curve and eliminates premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the BAT16484000 shipped or sat installed for several weeks without use, the cell voltage may have dropped below 2.5V — the point at which the BMS locks out to prevent damage. The phone will show no response to the power button. Connect the original charger and leave it for 20–30 minutes without pressing anything; the charge IC will trickle current into the cell until the BMS unlocks, typically recovering at around 3.0V before normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392049741914,"sku":"BWCS-DGX520SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392049774682,"sku":"BWCS-DGX520SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392049807450,"sku":"BWCS-DGX520SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DGX520SL-1.webp?v=1779143470","url":"https:\/\/batteryweb.com\/products\/doogee-x5-max-pro-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
