It replaces OEM part AP20A7N and KT.00407.010. Fit models include the PT314-51S-52ML, PT314-51S-52X6, PT314-51S-54AN, PT314-51S-54GB, and over 76 additional PT314-51S variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePT314-51S series fitment:\u003c\/strong\u003e\n    All PT314-51S variants share the same 15.48V four-cell architecture, AP20A7N OEM part number, and identical BMS connector pinout — that is why one cell fits the full range 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 charge and full-load discharge on the PT314-51S platform. The BMS handshake completed without fault codes, and the cell held voltage within spec across sustained CPU plus GPU draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Triton 300 SE:\u003c\/strong\u003e\n    After fitting, run one full discharge until the laptop hibernates at low-battery cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor after replacement on the PT314-51S\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Triton 300 SE BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported state. A fresh cell has no accumulated cycle data, so the BIOS flags it as unknown or degraded on first boot. This is not a fault with the replacement cell — it is the firmware interpreting missing history as damage. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% to begin building cycle data the BIOS can read correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC calibrates its discharge curve against the original cell's chemistry profile. With a new cell installed, the IC has no accurate model yet, so it misjudges the voltage-to-capacity curve and triggers shutdown before the display percentage reaches zero. Under full CPU plus display load the voltage cliff arrives faster than the gauge predicts. Run two to three full discharge-recharge cycles and the fuel gauge IC will recalibrate against the new cell — shutdowns should stop occurring above 5% after that.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409525571674,"sku":"BWCS-ACT300NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409525604442,"sku":"BWCS-ACT300NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409525637210,"sku":"BWCS-ACT300NB-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACT300NB-1.webp?v=1779579904","url":"https:\/\/batteryweb.com\/products\/acer-predator-triton-300-se-pt314-51s-52ml-replacement-battery-1548v-3850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
