It slots into the rear battery bay of the A116 and connects to the same three-contact board connector as the factory cell. Dimensions are 69.88 × 59.87 × 4.60mm — confirm these against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA116 Canvas HD fit:\u003c\/strong\u003e\n    The Canvas HD uses a removable rear-cover design with a dedicated battery bay sized to this cell's footprint. The BMS communicates state-of-charge data to the OS through the three-contact connector — voltage, temperature, and ID line all pass through the same point.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge-discharge cycles on the A116 board and confirmed the BMS accepted the cell, completed a full CC-CV charge cycle, and passed temperature readings to the OS without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, complete one full discharge-to-charge cycle without interruption. This lets the fuel gauge IC map the new cell's discharge curve before the OS starts reading percentage from it — skipping this step causes erratic percentage display for several days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the A116 Canvas HD reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A116 uses a fuel gauge IC that stores the previous cell's discharge curve in memory. When a new cell goes in, the IC still references the old curve until it runs a full calibration cycle. This mismatch causes the percentage reading to lag, jump, or plateau — the cell voltage is accurate, but the displayed figure is not. One full uninterrupted discharge followed by a complete charge to 4.2V resets the learned curve and restores accurate percentage display.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated yet and the cell hits a voltage cliff under load — typically during mobile data, screen-on, or a call. The OS sees 25% but the cell voltage drops below the BMS cutoff threshold under that current draw. The BMS trips and the phone shuts off to protect the cell. Run two full discharge-charge cycles and the fuel gauge will track voltage sag more accurately, pushing the shutdown trigger down to the correct low-voltage floor near 3.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404307693658,"sku":"BWCS-MCT500SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404307726426,"sku":"BWCS-MCT500SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404307759194,"sku":"BWCS-MCT500SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCT500SL-1.webp?v=1779369735","url":"https:\/\/batteryweb.com\/products\/micromax-a116-canvas-hd-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
