SKU CH-435C-VKJZC

Lithium CMOS battery restores BIOS settings and real-time clock on compatible LG Z1 Pro Express Dual laptops

  • Battery TypeLithium
  • Keeps BIOS settings alive with lithium CMOS cell
  • Direct replacement for LG Z1 Pro Express Dual motherboard
  • Pre-tested unit ensures reliable first-boot operation
  • Single battery packaged for immediate swap-out
  • Restores system clock and hardware config after power loss

Compatible CMOS Battery for LG Z1 Pro Express Dual

This lithium CMOS battery is designed for the LG Z1 Pro Express Dual laptop motherboard. It replaces a faulty or depleted BIOS RTC cell so the system keeps correct time and firmware settings. The part is new and tested before shipping. It is not a main laptop power battery.

Thermals Noise and Power Draw

As a passive coin cell the battery generates no heat and makes no sound during normal operation. Its lithium chemistry provides a low self-discharge rate so the motherboard retains CMOS data for years without drawing measurable power from the mains adapter.

Included Battery and Testing

The package contains one CMOS battery that has been checked for voltage and continuity before dispatch. No cables, brackets or software utilities are supplied. The pre-ship test simply confirms the cell is functional; it does not extend the motherboard warranty or provide diagnostic tools.

Highlights

  • Direct replacement for LG Z1 Pro Express Dual motherboard
  • Pre-tested unit ensures reliable first-boot operation
  • Single battery packaged for immediate swap-out
  • Restores system clock and hardware config after power loss

Questions about this item

How do I install the CMOS battery on the LG Z1 Pro Express Dual motherboard, and which step is often done incorrectly?

Disconnect the main battery and power adapter, then unplug the old CMOS battery connector from the motherboard header and attach the new lithium cell's connector in the same orientation; the step most often missed is forgetting to disconnect the main power sources first, which can cause a short.

What maintenance or replacement will this CMOS battery need later?

The lithium CMOS battery requires no routine maintenance; it will need replacement only when the system clock loses time or BIOS settings reset, typically after several years of operation.

What limit appears first under sustained use of this CMOS battery?

The first limit is the lithium cell's finite capacity; after prolonged use the voltage drops below the threshold needed to maintain the real-time clock and BIOS settings, requiring battery replacement.
