It matches the OEM part number P5015 and fits the phone's battery bay directly. Capacity and voltage figures come from product data, not estimates.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eL-ITE 502 fitment:\u003c\/strong\u003e\n    The L-ITE 502 uses a fixed 3.8V single-cell Li-Polymer architecture. This replacement matches that voltage rail and the physical footprint — 73.60 × 57.70 × 3.90 mm — so the connector seats without forcing.\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 bench. The BMS accepted handshake from the phone's charge IC without flagging an error, and the protection circuit tripped correctly at low-voltage cutoff as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge reset:\u003c\/strong\u003e\n    On first use after fitting, disable fast charging and run one full discharge down to automatic shutdown, then charge to 100% uninterrupted. This gives the phone's fuel gauge IC a clean reference curve against the new cell before it starts compensating for load.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the L-ITE 502 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe L-ITE 502 uses a fuel gauge IC that tracks charge state using a stored discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry, so the reported percentage drifts — often reading 80% when the cell is closer to 50%. The IC needs at least one full uninterrupted discharge-charge cycle to recalibrate its coulomb counter against the new cell. Until that cycle completes, percentage readouts will be inaccurate. Run the phone down to auto-shutdown and charge straight to 100% without interruption to lock in the corrected curve.\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 fuel gauge IC is still running on the old cell's voltage curve and the reported percentage doesn't match actual cell voltage. The modem or screen draws a short burst of current, the cell voltage drops below the BMS cutoff threshold before the OS can respond, and the phone cuts off hard. It's not a faulty cell — it's a calibration mismatch. Complete one full discharge-charge cycle without fast charging enabled, and the fuel gauge will remap its voltage cliff to the correct point on the new cell's curve, typically resolving the shutdown above 3.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392071794778,"sku":"BWCS-LCL502SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392071827546,"sku":"BWCS-LCL502SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392071860314,"sku":"BWCS-LCL502SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LCL502SL-1.webp?v=1779143621","url":"https:\/\/batteryweb.com\/products\/logicom-l-ite-502-replacement-battery-38v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
