It replaces OEM part numbers SNN5542A and SNN5542B. Fit is confirmed against the original connector and cell housing dimensions before any unit ships.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT2288 \/ V2260 platform compatibility:\u003c\/strong\u003e\n    These models share the same battery bay geometry, connector pin-out, and nominal voltage rail. One cell spec covers all listed variants without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a T2288 unit. The charge IC accepted the cell without fault codes, and the BMS handshake completed normally on first contact.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, run one full discharge down to automatic cutoff before charging back to 100%. Ni-MH cells have a defined voltage curve the phone's fuel gauge must map — skipping this step causes the percentage counter to read inaccurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the T2288 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T2288 uses a fuel gauge IC that tracks charge state by comparing accumulated current flow against a stored discharge curve from the previous cell. When a new cell goes in, that stored curve no longer matches the actual chemistry. The IC keeps reading against old data until it sees one complete discharge-to-cutoff cycle. Until that cycle runs, the percentage display will be off — sometimes by 20% or more at mid-charge states.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shuts off suddenly at 20–30% remaining after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a voltage cliff near end of discharge — the terminal voltage drops sharply and the phone's low-voltage protection trips before the gauge catches up. This is most common on a new cell that hasn't been calibrated yet, because the fuel gauge misjudges how much usable capacity remains. Run one full discharge cycle to let the IC anchor its cutoff prediction to the new cell's actual voltage curve. After that cycle, sudden shutoffs at 25–30% typically stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409511088218,"sku":"BWCS-MOT2288SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409511120986,"sku":"BWCS-MOT2288SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409511153754,"sku":"BWCS-MOT2288SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MOT2288SL-1.webp?v=1779579871","url":"https:\/\/batteryweb.com\/products\/motorola-t2288-replacement-battery-36v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
