It powers the real-time clock and CMOS memory, keeping system time and BIOS settings intact when mains power is removed. When the original cell depletes, the system loses its clock and may reset BIOS configuration on every cold boot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVOT133 and VS14165 fit:\u003c\/strong\u003e\n    Both models use the same RTC circuit and CR2032CL-58 footprint. The cell sits on the same motherboard socket with identical polarity orientation and no BMS handshake — a direct socket swap covers both units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We measured open-circuit voltage at 3.00–3.05V before installation. On the VOT133 board, the RTC held time correctly across repeated power-off cycles and the CMOS checksum passed POST without error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRTC swap procedure for the VOT133:\u003c\/strong\u003e\n    This is a desktop CMOS cell, not a hot-swap unit. Shut the system down fully and unplug the AC cable before opening the chassis. After fitting the new cell, re-enter BIOS on first boot to reset the system date and time — the RTC does not retain values from the dead cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VOT133 shows the wrong date and time after a cold boot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CR2032CL-58 is the sole power source for the RTC when AC power is absent. Once cell voltage drops below roughly 2.5V, the RTC circuit loses its reference and the clock resets to a default date — typically January 1, 2000 or the BIOS compile date. The system may also flag a CMOS checksum error at POST because stored settings are no longer validated against a live cell. Replacing the cell and manually resetting the clock in BIOS resolves both symptoms immediately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS settings reverting to defaults after every shutdown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf boot order, onboard device settings, or custom BIOS values reset every time the VOT133 is unplugged, the CMOS cell is no longer holding charge between sessions. A depleted cell reads below 2.0V under the light load of the RTC circuit — enough for POST to pass once but not enough to retain NVRAM writes. Fit the new CR2032CL-58, power the system on, re-enter BIOS, save all settings with F10, then confirm they persist across a full shutdown and cold boot. If settings still revert, check the cell socket for corrosion or a bent retaining clip preventing firm contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415963500634,"sku":"BWCS-VSN133BU-1","price":15.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415963533402,"sku":"BWCS-VSN133BU-2","price":17.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415963566170,"sku":"BWCS-VSN133BU-3","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VSN133BU-1.webp?v=1779758652","url":"https:\/\/batteryweb.com\/products\/viewsonic-nettop-vot133-replacement-battery-3v-220mah-lithium","provider":"BatteryWeb","version":"1.0","type":"link"}
