It replaces OEM part numbers DR36 and DR36S. Install it when the original cell can no longer hold a usable charge or fails to power the machine away from AC.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBN200 and Note Jet III compatibility:\u003c\/strong\u003e\n    These Canon notebook lines share the same 12V power rail, physical connector, and DR36 battery housing. The BMS handshake and charge termination voltage are identical across the BN200, BN750, and Note Jet III CX P120 — one cell fits all.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on Canon notebook hardware. The BMS hit correct delta-V cutoff at top-of-charge and the protection circuit tripped cleanly at low-voltage threshold with no false mid-cycle shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on Canon notebooks:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it hibernates, then charge uninterrupted to 100%. Canon notebooks store battery learn data in BIOS — skipping this step leaves the fuel gauge reading from the old cell's degraded profile, which causes premature low-battery warnings.\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 immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eCanon notebook BIOS stores charge-cycle count and capacity data in EEPROM on the battery controller. When a new cell is fitted, the BIOS reads that EEPROM data and compares it against internal thresholds — a fresh cell with no cycle history can trigger a \"battery degraded\" or \"replace battery\" flag because the data does not match what the firmware expects from a calibrated pack. This is not a fault with the replacement cell. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% to force the BIOS battery learn cycle to reset against the new cell's actual capacity curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts off at 20–30% charge shown on the indicator\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a steeper voltage drop curve than Li-ion. Under combined CPU and display load, an uncalibrated fuel gauge IC cannot accurately track where the cell's true voltage cliff sits. The OS gauge shows 20–30% remaining, but the actual cell voltage has already dropped below the BMS cutoff threshold under load — so the laptop cuts out. Run two to three full discharge-to-hibernate cycles with the battery calibrating against this specific cell. After calibration, the fuel gauge IC re-maps the voltage cliff to the correct state-of-charge percentage, typically below 10%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410856050778,"sku":"BWCS-DR36HB-1","price":89.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410856083546,"sku":"BWCS-DR36HB-2","price":105.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410856116314,"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\/canon-bn200-replacement-battery-12v-3800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
