It replaces the original battery when the device no longer holds a charge after repeated charge cycles. Rated at 6.11Wh and measuring 70.50 × 60.00 × 4.00mm, it matches the factory cell dimensions and connector layout.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOrion Pro and X500a compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pin-out, and BMS handshake protocol — the 1ICP38\/55\/67 part number covers both variants 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 a full charge and discharge on the Orion Pro platform. The BMS accepted the charge cycle without triggering overcurrent cutoff, and voltage held steady through screen-on and modem-active load states.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging for the first complete discharge-charge cycle. The Orion Pro's fuel gauge IC is calibrated to the old cell's discharge curve. Running one slow cycle lets it remap against the new cell before high-current charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Orion Pro reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Orion Pro uses a fuel gauge IC that tracks charge state by measuring accumulated current flow — a coulomb counter method. When you swap the physical cell, the IC still references its stored discharge curve from the old battery. The new cell has a slightly different internal resistance and capacity curve, so the reported percentage drifts from the actual state of charge. One full discharge to auto-shutdown followed by a full slow charge resets the counter and retrains the curve against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the modem's minimum operating threshold under combined screen and radio load — even though the fuel gauge still reads 20–30%. A fresh Li-ion cell has slightly higher internal impedance before the first few cycles break it in, which causes a sharper voltage sag under peak draw. The phone's protection circuit reads the sag as a cutoff condition and shuts down before the displayed percentage reaches zero. After two or three full charge-discharge cycles, cell impedance drops and voltage sag stabilises — confirmed stable hold at or above 3.5V under load on our bench after cycle three.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404156403802,"sku":"BWCS-POX500SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404156436570,"sku":"BWCS-POX500SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404156469338,"sku":"BWCS-POX500SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-POX500SL-1.webp?v=1779369095","url":"https:\/\/batteryweb.com\/products\/posh-orion-pro-replacement-battery-37v-1650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
