It fits the compact battery bay on this handset and restores power to calling, messaging, and basic data functions. Capacity figures come from the product specification — 800mAh, 2.96Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRenue P6030 platform fit:\u003c\/strong\u003e\n    The P6030 uses a single Li-ion cell at 3.7V nominal with a fixed connector pinout tied to the BMS on the main board. This replacement matches that voltage rail and connector geometry so the handset's charge IC recognises the cell without a firmware conflict.\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 P6030 platform and confirmed the BMS accepted the cell, terminated charge correctly at full voltage, and held the protection threshold at the low end without tripping into lockout under normal load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After fitting a new cell, run one complete discharge down to auto-shutoff, then charge uninterrupted to 100% before normal use. This gives the fuel gauge IC a full reference curve against the new cell so percentage readings stay accurate from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Renue P6030 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe P6030 uses a fuel gauge IC that builds its charge model from the discharge curve of the cell it was last calibrated against. Swap in a new cell and the IC is still reading from its old curve — so the percentage shown on screen does not match what the new cell is actually delivering. This mismatch usually shows up as sudden jumps in the indicator or a reading that reads 30% and then drops to shutdown immediately. One full discharge-to-shutoff followed by a complete charge resets the coulomb counter and re-anchors the gauge to the new cell's actual capacity.\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 sharply under the load spike from the modem or display backlight — a voltage cliff the original aged cell masked because it had settled into a softer discharge curve. A new cell has lower internal impedance and a steeper cutoff near 3.0V per cell, so the BMS trips protection before the OS percentage reading catches up. The fix is the same calibration cycle: one full discharge to auto-shutoff, then a full uninterrupted charge. After that cycle the gauge tracks the new cell's actual voltage curve and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404331024474,"sku":"BWCS-PT6030SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404331057242,"sku":"BWCS-PT6030SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404331090010,"sku":"BWCS-PT6030SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PT6030SL-1.webp?v=1779369778","url":"https:\/\/batteryweb.com\/products\/pantech-renue-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
