It fits the Motorola A910, E770, E1070, and V1050, along with nine additional models sharing the same battery bay and connector footprint. The cell measures 53.91 × 35.22 × 5.60 mm and slots directly into any of these handsets without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA910 \/ E770 \/ E1070 \/ V1050 platform fit:\u003c\/strong\u003e\n    These handsets share the same physical bay dimensions, three-pin connector layout, and 3.7V single-cell rail. The BT-60 spec covers all of them — Motorola used one battery platform across this mid-2000s lineup to simplify service, so a single cell replacement covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full discharge and recharge on the A910 platform and monitored the BMS handshake at each stage. The protection circuit responded correctly to cutoff thresholds at both ends of the charge window, and the fuel gauge IC accepted the new cell without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable any fast-charge accessory and run one full discharge-to-charge cycle before normal use. The fuel gauge IC on these handsets is calibrated against the old cell's discharge curve — one clean cycle against the new cell lets it reset its coulomb counter and report accurate percentages from that point forward.\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 A910 after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the old cell's discharge curve in memory. When the phone's modem or display pulls a current spike, the new cell's voltage drops below the shutdown threshold faster than the gauge predicts — so the phone cuts out while the reported percentage still looks safe. The fix is one full calibration cycle: charge to 100%, drain to automatic shutdown without intervention, then charge back to full without interruption. After that cycle, the coulomb counter maps correctly to the new cell and the early shutoffs stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after sitting in storage with a flat battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored fully discharged will drop below 2.5V, at which point the BMS locks out to prevent cell damage. The A910 shows nothing on screen and does not respond to the power button — which many users mistake for a dead replacement cell. Connect the handset to a wall charger rather than a USB port, since wall adapters supply enough current to nudge the BMS out of lockout. Leave it connected for at least 15 minutes before attempting to power on; by that point the cell should read above 3.0V and the BMS will release.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409512988762,"sku":"BWCS-MOA910SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409513021530,"sku":"BWCS-MOA910SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409513054298,"sku":"BWCS-MOA910SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MOA910SL-1.webp?v=1779579852","url":"https:\/\/batteryweb.com\/products\/motorola-a910-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
