It covers the 83DR series, including models 83DR0000SB, 83DR0002US, 83DR0003JP, 83DR0004JP, and 453 additional regional variants. OEM part numbers L23B3PE1, L23C3PE1, L23D3PE1, L23L3PE1, L23M3PE1, 5B11M74074, 5B11M74076, 5B11M74077, SB11M74072, and SB11M74073 all fit this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e83DR series compatibility:\u003c\/strong\u003e All 83DR variants share the same 11.31V three-cell architecture, connector pinout, and BMS handshake protocol. The fuel gauge IC communicates over SMBus — same wiring across every regional SKU in this generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran this cell through charge and discharge cycles on an 83DR unit. The BMS handshake completed on first boot, charge current ramped correctly through CC\/CV phases, and the protection circuit tripped within spec on an over-discharge test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e After fitting this battery, run the laptop down to hibernate-cutoff on light load, then charge uninterrupted to 100%. This forces the fuel gauge IC to learn the new cell's actual capacity and clears the inaccurate health warning the BIOS flags after every 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lenovo BIOS reads health data from the battery's EEPROM, which stores cycle count and rated capacity from the original cell's firmware. A new cell arrives with fresh EEPROM values that don't match the laptop's stored learn-cycle history, so the BIOS flags it as degraded. This is a data mismatch — not a fault with the new cell. Run the full discharge-to-hibernate then uninterrupted charge cycle once. After one complete learn cycle the BIOS recalculates health against the new cell's actual charge curve and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% shown on the battery meter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated against the new cell's voltage curve. The gauge is still using the old cell's discharge model, so it misreads remaining capacity — the cell actually hits its low-voltage cutoff well before the meter reaches zero. Under combined CPU and display load, the voltage drops faster than the stale model predicts, triggering a hard shutdown. One full discharge-to-hibernate cycle resets the gauge's reference points. After that cycle the shutdown threshold stabilises above 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409643012186,"sku":"BWCS-LVP830NB-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409643044954,"sku":"BWCS-LVP830NB-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409643077722,"sku":"BWCS-LVP830NB-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVP830NB-1.webp?v=1779579852","url":"https:\/\/batteryweb.com\/products\/lenovo-83dr0000sb-replacement-battery-1131v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
