It fits the 3700, 3715, 3700ED, and 3700EH, among other models in the same series. OEM part numbers SA20080-01, 23-050260-00, and 23+050260+00 all cross-reference to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3700 series compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell voltage rail, connector pinout, and BMS handshake protocol — one cell services the full lineup 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 discharge on the 3700 platform. The BMS negotiated correctly, charge termination triggered at full voltage, and no overcurrent faults were logged during the load phase.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on the 3700:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells 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\"\u003eWhy the Averatec 3700 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 3700's BIOS reads health data stored in the outgoing cell's EEPROM and compares it against the new cell's reported capacity. A fresh cell with no cycle history looks mismatched against those stored values. The BIOS flags this as degraded health even though the cell is new. Running a full discharge-to-hibernate followed by an uninterrupted charge gives the fuel gauge IC enough data to recalibrate against the new chemistry and clear the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAveratec 3700 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a cell can no longer hold voltage under full CPU and display load simultaneously — the voltage drops below the BMS cutoff threshold before the gauge reaches zero. The fuel gauge IC is still reading stored data from the old cell, so the percentage on screen is not tracking the new cell's actual voltage curve. Run two full discharge-to-charge calibration cycles after installation. After calibration, the gauge should align with real cell voltage; if shutdowns persist below 10.5V under load, check the charge adapter output.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410826952794,"sku":"BWCS-AT3800NB-1","price":80.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410826985562,"sku":"BWCS-AT3800NB-2","price":94.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410827018330,"sku":"BWCS-AT3800NB-3","price":105.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AT3800NB-big.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/averatec-3700-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
