It replaces OEM part AP18L4N across a wide range of P614 variants including the TMP614-51, TMP614-51T, and TMP614-51G. It fits the physical tray and uses the same connector and BMS communication protocol as the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTravelMate P614 series fit:\u003c\/strong\u003e\n    All P614 variants covered here share the same 15.2V four-cell Li-Polymer architecture, identical connector pinout, and the same BMS handshake that Acer's embedded controller expects. Swapping between sub-models does not require a different cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a P614-51 unit. The BMS negotiated charge current correctly, the embedded controller accepted the cell without fault codes, and the protection circuit tripped at the expected low-voltage threshold before hibernate cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation calibration:\u003c\/strong\u003e\n    After fitting, run the laptop down to hibernate on battery — do not plug in early. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TravelMate P614 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe P614's fuel gauge IC calibrates its state-of-charge map against the original cell's discharge curve. A new cell has a different impedance profile, so the IC's internal model no longer matches actual voltage behaviour under load. When the CPU and display pull full current, voltage drops sharply — faster than the old model predicted — and the system hits an emergency cutoff point before the gauge reads zero. Running two to three full discharge-to-hibernate cycles allows the fuel gauge IC to rebuild its curve against the new cell and eliminates premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting \"poor battery health\" immediately after fitting a new AP18L4N cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAcer's BIOS reads health state from EEPROM data stored in the battery's own management circuit. On a new replacement cell, the EEPROM cycle count and capacity registers may not match what the BIOS expects from a fresh unit, triggering a poor-health flag even though the cell is new. This is an EEPROM data mismatch — not a fault with the cell itself. Run a full battery learn cycle: discharge fully to hibernate, then charge uninterrupted to 100%. After one complete cycle, the BIOS health flag clears and the reported status updates to reflect actual cell condition.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409652449370,"sku":"BWCS-ACP614NB-1","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409652482138,"sku":"BWCS-ACP614NB-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409652514906,"sku":"BWCS-ACP614NB-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACP614NB-1.webp?v=1779580296","url":"https:\/\/batteryweb.com\/products\/acer-travelmate-p614-replacement-battery-152v-3850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
