The Twin View Dock is a dual-screen tablet accessory that pairs with the ROG Phone, and this cell powers the dock's secondary display and onboard hardware independently of the phone. Capacity figures here come from the product data, not third-party estimates.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTwin View Dock ZS600KLS fit:\u003c\/strong\u003e\n    The dock uses a single-cell Li-ion pack at 3.7V nominal, isolated from the ROG Phone's own battery. The BMS connector and voltage rail match the OEM spec, so the dock's charging circuitry recognises the cell without a handshake error on reconnection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the dock's charge IC and confirmed the BMS did not trigger an over-voltage cutoff at full charge, and held the low-voltage floor correctly — the dock's display stayed active under sustained load without an unexpected cutoff event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one full discharge down to automatic shutoff, then charge uninterrupted to 100% before re-enabling fast charging. The dock's coulomb counter is still mapped to the old cell's discharge curve and will report inaccurate percentages until it completes one calibration cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Twin View Dock shuts down while the percentage still shows above 15%\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a slightly different internal resistance profile than the depleted OEM battery it replaces. Under the current draw of the secondary display, the dock's BMS sees a voltage dip that crosses the low-voltage cutoff threshold before the fuel gauge catches up. The percentage reading lags because the coulomb counter was calibrated to the old cell's slower voltage curve. One full discharge-charge cycle corrects the mapping and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDock not powering on after sitting in storage for several months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left uncharged for extended periods can drop below the BMS lockout threshold — typically around 2.5V per cell. When that happens, the protection circuit disconnects the output and the dock appears completely dead. Connect the dock to its charger and leave it for 15–20 minutes without pressing the power button; most BMS circuits begin a trickle pre-charge recovery below 2.9V. If the charging LED does not activate within 30 minutes, the cell has discharged too far for the BMS to self-recover and a replacement cell is required.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391872467034,"sku":"BWCS-AUZ600SL-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391872499802,"sku":"BWCS-AUZ600SL-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391872532570,"sku":"BWCS-AUZ600SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUZ600SL-1.webp?v=1779142412","url":"https:\/\/batteryweb.com\/products\/asus-twin-view-dock-zs600kls-replacement-battery-37v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
