Compatible CMOS Battery

The DBTLAP CMOS battery is a direct replacement for the Acer Aspire 5750G laptop motherboard. It restores the system clock and BIOS settings that are lost when the original cell fails. This lithium coin cell is not a main laptop battery and will not power the portable device itself. Buyers needing a primary power pack for mobile use should look elsewhere.

Sustained Reliability

Each unit is tested before shipping to confirm it holds a stable voltage under the continuous low-drain load of a motherboard real-time clock circuit. The lithium chemistry provides a steady output over years rather than the short bursts seen in high-current applications. A faulty or cracked original cell that causes CMOS checksum errors is resolved by this verified replacement.

Motherboard Interface Limits

The battery connects to the standard two-pin header found on the compatible motherboard, delivering the 3 V nominal potential required by the RTC and CMOS memory block. Polarity and physical dimensions must match the board layout exactly; no adapter or soldering provision is included. Systems with a different connector pitch or voltage requirement cannot use this cell.

Questions about this item

How much power does the CMOS battery draw while the Acer Aspire 5750G runs all day?

The lithium CMOS battery only supplies a tiny standby current to keep the real-time clock and BIOS settings alive; it does not draw power from the mains while the laptop is running.

What must I already have to install this CMOS battery in my Acer Aspire 5750G?

You need a small Phillips screwdriver to open the chassis and access the motherboard header where the battery plugs in.

Will this replacement CMOS battery work with the original motherboard firmware on an older Acer Aspire 5750G?

Yes, it is a direct lithium cell replacement that restores BIOS time and settings on the existing motherboard without any firmware update.
