It replaces OEM part numbers BTP-41D1, BTP41D1, and 60.45H03.011. Fits directly into the original battery bay with no modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTravelMate 350 series compatibility:\u003c\/strong\u003e\n    The 350, 351, 352, and 353 share the same battery bay format, connector pinout, and 11.1V three-cell power rail. One cell fits the full group — no adapter or wiring change needed.\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 TravelMate hardware. The BMS communicated correctly with the system board, accepted a full charge, and held voltage within spec across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after install:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on the first boot after any cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TravelMate BIOS reads health data stored in the old cell's EEPROM and carries a cached state into the first session with the new battery. This is not a fault with the replacement cell — it is stale data from the previous unit. Running one full discharge-to-hibernate then a full uninterrupted charge forces the BIOS to rewrite its battery learn data against the new cell. After that cycle, the health indicator should return to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTravelMate shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual chemistry. The gauge shows 20–30% remaining, but the cell voltage has already dropped below the threshold the system board needs to sustain the CPU and display together under load. It reads as a sudden shutdown rather than an orderly hibernate. Run two to three full discharge-and-charge cycles — the fuel gauge IC recalibrates against real cell behaviour each time. After calibration, the gauge and actual voltage should align, with low-battery warnings triggering above 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410864439386,"sku":"BWCS-AC360NB-1","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410864472154,"sku":"BWCS-AC360NB-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410864504922,"sku":"BWCS-AC360NB-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AC360NB-1.webp?v=1779581402","url":"https:\/\/batteryweb.com\/products\/acer-travelmate-350-replacement-battery-111v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
