DBTLAP CMOS Battery for Acer Aspire V3-772G

SKU CH-82N1-RPMF0

Lithium CMOS battery replaces the BIOS clock cell in Acer Aspire V3-772G laptops

  • Battery TypeLithium
  • Compatible replacement for Acer Aspire V3-772G
  • Lithium chemistry provides reliable BIOS timekeeping
  • Tested before shipping ensures dependable operation
  • New CMOS battery restores motherboard RTC function
  • Single unit included for straightforward installation

Compatible CMOS Battery for Aspire V3-772G

This DBTLAP lithium CMOS battery is designed for the Acer Aspire V3-772G laptop motherboard. It replaces a faulty or depleted BIOS RTC cell to restore system clock and firmware settings. The part is supplied new and tested before shipping. It is intended for motherboard maintenance, not as a main laptop power source.

Thermals Noise and Power Draw

As a passive lithium coin cell, the battery generates no heat and produces zero audible noise during operation. Power draw is negligible, limited to the microampere current required to maintain the real-time clock and CMOS memory when the laptop is off. No active cooling or power management is involved.

Lithium Chemistry and Motherboard Fit

The single specification that determines compatibility is the lithium chemistry matched to the motherboard's RTC circuit. The cell is built to the form factor expected by the Aspire V3-772G board. Buyers whose laptop uses a different coin-cell size or voltage should verify the exact part number before ordering.

Questions about this item

How do I install the CMOS battery in my Acer Aspire V3-772G, and what step is often missed?

Open the chassis, locate the coin cell on the motherboard, remove the old battery noting its orientation, insert the new lithium cell with the same polarity, then enter BIOS to reset the date and time.

What maintenance will this CMOS battery need later?

The lithium cell requires no routine maintenance; when the system clock drifts or BIOS settings clear, power off the laptop and swap the battery for a fresh unit.

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

The cell voltage gradually drops over years of continuous operation; once it falls below the threshold needed to retain CMOS data, the clock and BIOS settings will be lost.
