It uses OEM part number BL160 and slots into either handset using the original rear-cover latch. Swap it when the original cell no longer holds a usable charge through a normal day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eI200 and I520 compatibility:\u003c\/strong\u003e\n    Both models share the BL160 form factor — same 53.37 × 9.72 × 4.10 mm footprint, same 3.7V nominal rail, and the same connector pinout. No adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the cell through charge and discharge on a Lenovo I520 test unit. The BMS accepted the charge handshake cleanly, held voltage above 3.5V under steady screen and call load, and tripped the low-voltage cutoff at the correct threshold without early dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging if available and run one full discharge down to auto-off, then charge uninterrupted to 100%. This gives the fuel gauge IC a clean reference curve against the new cell before the OS starts drawing on that data for percentage estimates.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Lenovo I200 and I520\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage collapses faster than the fuel gauge IC predicts under a high-current spike — typically the modem transmitting or the screen at full brightness. The old cell's discharge curve is baked into the coulomb counter, so the OS shows 25% right up until the voltage drops below the BMS cutoff threshold. After installing the BL160 replacement, run one complete discharge-to-shutdown cycle followed by a full uninterrupted charge. The fuel gauge IC will rewrite its reference curve against the new cell, and percentage readout will stabilise by the second full cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shows wrong battery percentage after the cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on both the I200 and I520 stores a learned discharge curve from the original cell. When a new cell goes in, the IC keeps using the old curve, so the percentage shown on screen does not match actual remaining capacity — it may jump, drop suddenly, or read 100% while the phone is nearly flat. Force a recalibration by draining the phone fully until it shuts off, then charging in one session to 100% without interruption. After that single cycle, the coulomb counter recalibrates to the BL160's actual discharge profile. Expect the readout to stabilise to within a few percent of true capacity from that point forward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404317655130,"sku":"BWCS-LVI520SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404317687898,"sku":"BWCS-LVI520SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404317720666,"sku":"BWCS-LVI520SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVI520SL-1.webp?v=1779369680","url":"https:\/\/batteryweb.com\/products\/lenovo-i200-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
