It restores power to handsets where the original cell has degraded and can no longer hold a usable charge. Dimensions are 72.00 × 58.50 × 4.55mm — confirm these against your original before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX130 platform compatibility:\u003c\/strong\u003e\n    The 2S, X130V, X130W, and X130wa all share the same battery bay dimensions, 3.7V single-cell architecture, and connector pinout, which is why one cell covers the full group. No adapter or rewiring needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a PHICOMM handset and confirmed the BMS accepted charge handshake without fault codes. Capacity measured within normal tolerance of the rated 2200mAh at standard draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration tip:\u003c\/strong\u003e\n    On first use after fitting, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging starts — skipping this step causes erratic percentage readings for days.\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 a freshly fitted BL-F17\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the phone's fuel gauge IC still holds the discharge curve from the old, degraded cell. The new cell hits a voltage cliff — a sharp voltage drop under modem or screen load — at a point the IC incorrectly reads as 20–30% remaining. The phone interprets that voltage sag as a safe-shutdown threshold and cuts out. One full discharge from 100% down to automatic shutoff, then a full uninterrupted charge, resets the coulomb counter and clears this behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the BL-F17 sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the BL-F17 dropped below roughly 2.5V per cell, the BMS enters lockout mode to prevent damage — and a locked-out BMS looks identical to a dead battery. Connect the phone to a wall charger, not a PC USB port, and leave it for 20–30 minutes without pressing the power button. The charge IC trickle-charges the cell back above the BMS unlock threshold, typically around 2.9V, at which point the BMS re-initialises and the phone will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404197101658,"sku":"BWCS-PMX130SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404197134426,"sku":"BWCS-PMX130SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404197167194,"sku":"BWCS-PMX130SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMX130SL-1.webp?v=1779369370","url":"https:\/\/batteryweb.com\/products\/phicomm-2s-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
