It matches OEM part numbers 533-000088 and HB303450. When the original cell fails, gesture tracking and wireless connectivity drop out entirely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT650 and MX Master compatibility:\u003c\/strong\u003e\n    Both devices share the same battery bay dimensions, voltage rail, and connector footprint. The 51.55 × 34.80 × 3.60mm cell slots into either unit without modification to the housing or cable routing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a T650 unit. The BMS accepted the cell without triggering a protection cutoff, and the device recognised a full charge state on first connect to the charging cable.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eInternal battery swap caution:\u003c\/strong\u003e\n    The T650 uses a soldered or clip-seated ribbon connector — not a standard tab. Disconnect the old cell from the PCB before cutting any adhesive. Pulling the cell first risks tearing the connector pad off the board.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the T650 stops tracking after a partial charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells in low-draw devices like the T650 degrade through shallow cycling — repeated short charges that never complete a full charge-discharge cycle. Over time, the usable voltage window narrows. The touchpad's wireless module cuts out before the BMS trips because the radio needs a stable 3.5V minimum to maintain Bluetooth connection. A cell that reads 3.6V at rest may sag below that threshold under the brief transmit load. Replace the cell and run one full charge before pairing the device again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTouchpad connects but drops gestures mid-use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the cell voltage is holding at rest but sagging during multi-finger gesture bursts, which spike the wireless transmitter draw. The BMS doesn't cut off, but the radio stutters. Users report it as a software or driver issue — it's nearly always a low-cell symptom. Check the battery indicator in Logitech Options software first. If it reads below 20%, the new cell should resolve the drop-outs after a full charge to 4.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416101191770,"sku":"BWCS-LOT650SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416101224538,"sku":"BWCS-LOT650SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416101257306,"sku":"BWCS-LOT650SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LOT650SL-1.webp?v=1779760264","url":"https:\/\/batteryweb.com\/products\/logitech-touchpad-t650-replacement-battery-37v-500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
