It replaces OEM part numbers AC14B3K and KT.00403.032. If your original cell has degraded or won't hold a charge, this unit restores the laptop's portable operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAspire R3 and R3-131T compatibility:\u003c\/strong\u003e\n    These models share the same 15.2V four-cell architecture, connector pinout, and BMS communication protocol. The same cell works across the R3-131T-P4QQ and R5 variants because Acer kept the voltage rail and EEPROM handshake consistent across that generation.\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 an Aspire R3-131T. The BMS negotiated correctly with the motherboard, charge acceptance was normal from the first cycle, and the protection circuit tripped as expected at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Aspire R3:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. The Aspire R3's fuel gauge IC recalibrates against the new cell's actual capacity. Skipping this step causes the BIOS to report inaccurate health warnings for weeks.\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 fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Aspire R3 stores battery health data in EEPROM on the motherboard. When you swap cells, that stored data reflects the old, degraded battery — not the new one. Windows and the Acer BIOS will both flag poor health until the learn cycle is completed. Run a full discharge to hibernate, then a full uninterrupted charge. After two to three cycles the BIOS recalculates from actual cell data and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAspire R3 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff symptom. Under full CPU and display load, the cell voltage drops sharply below the BMS cutoff threshold while the fuel gauge still reads 20–30%. It usually means the fuel gauge IC hasn't yet calibrated its discharge curve to the new cell. Complete two full discharge-to-hibernate cycles. If the shutdowns continue after calibration, check the battery voltage under load with a multimeter — a healthy cell at 20% charge should hold above 14.8V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409732108378,"sku":"BWCS-ACR300NB-1","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409732141146,"sku":"BWCS-ACR300NB-2","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409732173914,"sku":"BWCS-ACR300NB-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACR300NB-1.webp?v=1779580541","url":"https:\/\/batteryweb.com\/products\/acer-aspire-r3-replacement-battery-152v-3200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
