It replaces the original battery when the cell loses capacity, swells, or stops holding a charge. Voltage and physical dimensions — 70.00 × 59.90 × 4.40mm — match the stock cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCanvas-series shared platform:\u003c\/strong\u003e\n    These models run on a common Mediatek board layout that shares the same battery connector pitch and BMS handshake voltage thresholds. That is why one cell covers the full Canvas range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Canvas HD A116 unit. The BMS accepted the charge handshake on the first cycle, and the fuel gauge IC tracked discharge without a false cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high current is pushed into an uncalibrated cell.\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 Canvas series after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Canvas-series fuel gauge IC stores a learned discharge curve from the old cell. When a new cell is installed, the IC applies the old curve to a cell with different impedance characteristics. Under modem load or screen-on draw, the new cell's voltage drops faster than the IC predicts, triggering an emergency cutoff before the OS can warn the user. Run two full discharge-charge cycles without interruption to overwrite the stored curve. After the second cycle, the IC recalibrates and the 20–30% shutoff stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after replacing the cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the coulomb counter inside the phone retains data from the previous cell and maps capacity readings to an outdated baseline. The result is percentage jumps, a stuck reading, or a rapid drop from 50% to zero. Drain the battery completely until the phone shuts off on its own, then charge uninterrupted to 100% without removing the cable. One full cycle is usually enough to re-anchor the coulomb counter to the new cell's actual capacity floor and ceiling.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404230819930,"sku":"BWCS-WKS011SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404230852698,"sku":"BWCS-WKS011SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404230885466,"sku":"BWCS-WKS011SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WKS011SL-1.webp?v=1779369465","url":"https:\/\/batteryweb.com\/products\/micromax-canvas-3d-a115-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
