It fits the dual-SIM slot configuration without any modification to the battery bay. Capacity is rated at 6.84Wh, matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-J110 series compatibility:\u003c\/strong\u003e\n    The Galaxy J1 Ace, J1 Ace Dual SIM 3G, and J1 Ace 3G Duos all share the same 3.8V battery rail, physical footprint, and connector pinout — which is why a single cell covers all variants in the SM-J110 lineup without BMS handshake conflicts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery on an SM-J110 unit and monitored BMS cutoff thresholds across three full charge-discharge passes. The protection circuit tripped correctly at low-voltage cutoff and the charge IC accepted the cell without error flags on the second cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. The fuel gauge IC in the SM-J110 calibrates its coulomb counter against the actual discharge curve — skipping this step on a fresh cell produces inaccurate percentage readings for the first several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Galaxy J1 Ace shuts down suddenly at 20–30% after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SM-J110's fuel gauge IC still holds the discharge curve from the old, degraded cell after a swap. When the new cell hits a voltage point the IC incorrectly maps to near-empty, it signals a low-voltage shutdown even though usable charge remains. This is a calibration mismatch, not a fault with the replacement cell. Run two or three full discharge-charge cycles and the IC rewrites its reference curve to match the new cell's actual voltage profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after installing the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy J1 Ace uses a coulomb counter that accumulates charge and discharge data over time to estimate state of charge. After a cell replacement, the counter has no valid baseline for the new cell's capacity, so percentage readouts jump or stall at fixed points — commonly 50% or 100%. Allow the battery to drain fully until the phone shuts off, then charge uninterrupted to 100% before first use. After two cycles, the coulomb counter stabilises and percentage reporting becomes accurate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392033947738,"sku":"BWCS-SMJ111XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392033980506,"sku":"BWCS-SMJ111XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392034013274,"sku":"BWCS-SMJ111XL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMJ111XL-1.webp?v=1779143086","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-j1-ace-3g-duos-replacement-battery-38v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
