It replaces OEM part numbers DR36 and DR36S. The battery restores portable power to laptops running depleted or failed original cells.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE12 Series fitment:\u003c\/strong\u003e\n    The E12 Series uses a shared battery bay with a consistent 12V rail and a standardised connector pinout across this notebook line. DR36 and DR36S are interchangeable OEM references for the same physical pack — both fit the same housing and connect to the same charge controller.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the E12 platform. The BMS accepted the new cell without fault flags, charge current stepped down correctly as the pack approached capacity, and the protection circuit tripped cleanly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation calibration on the E12:\u003c\/strong\u003e\n    After fitting this battery, run the notebook down to hibernate cutoff under normal use — do not force shutdown — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells in this notebook.\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 after fitting the DR36\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you swap a Ni-MH pack in the E12 Series, the BIOS reads stored EEPROM data from the previous cell and compares it against the new pack's initial state. The mismatch triggers a \"degraded\" or \"poor health\" flag even on a brand-new battery. This is not a fault with the replacement cell. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and brings the health readout in line with the actual cell condition.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFuel gauge reading wildly off for the first few charge cycles\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the E12 calculates remaining capacity against a stored charge profile built from previous cell data. A new Ni-MH cell with different internal resistance throws those calculations off immediately. The gauge corrects itself after two to three full discharge and recharge cycles as the IC builds a fresh profile. Do not judge the replacement pack on the first cycle — let it reach a stable resting voltage of around 12.0V before trusting the percentage readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410857164890,"sku":"BWCS-DR36HB-1","price":89.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410857197658,"sku":"BWCS-DR36HB-2","price":105.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410857230426,"sku":"BWCS-DR36HB-3","price":118.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DR36HB-big.webp?v=1779581376","url":"https:\/\/batteryweb.com\/products\/trogon-e12-series-replacement-battery-12v-3800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
