It matches the factory voltage, capacity, and physical dimensions at 72.00 × 58.00 × 4.80mm. Fit the replacement when the original cell can no longer sustain daily use through a full charge cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNitro 5P fitment:\u003c\/strong\u003e\n    The AHB425462P uses a specific connector pinout and flex tab position tied to the Nitro 5P's charge IC and BMS handshake. Only cells matching this footprint will seat correctly against the frame and connect to the fuel gauge IC without adapter modifications.\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 Nitro 5P platform. The BMS accepted the cell without fault flags, and the charge IC transitioned cleanly from bulk to taper phase at the correct cutoff voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC build a fresh discharge curve against the new cell before high-current charging pushes current into an uncalibrated state.\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 Nitro 5P after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nitro 5P's fuel gauge IC retains the discharge curve from the previous degraded cell. When the replacement cell hits a voltage point the old curve marks as 20–30%, the phone may cut power even though usable capacity remains. The phone shuts down because the IC interprets the voltage reading as critically low, not because the cell is actually depleted. One full discharge down to auto-shutoff followed by a complete charge resets the coulomb counter and maps the new cell's actual voltage cliff — typically near 3.2V under modem load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge in storage, and if a replacement cell drops below approximately 2.5V, the BMS enters lockout to prevent cell damage. The phone will show no response — no charge indicator, no boot — even when connected to a charger. Connect the phone to a wall adapter rated at least 5V\/1A and leave it undisturbed for 20–30 minutes before attempting to power on. Once the BMS sees voltage recover above its wake threshold, charging resumes normally and the phone will boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391782781018,"sku":"BWCS-MWP500SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391782813786,"sku":"BWCS-MWP500SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391782846554,"sku":"BWCS-MWP500SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MWP500SL-1.webp?v=1779141909","url":"https:\/\/batteryweb.com\/products\/maxwest-nitro-5p-replacement-battery-38v-2300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
