DBTLAP CMOS Battery for Acer 4551 4315

This replacement CMOS battery is designed for Acer Aspire 4551 and 4315 laptops. It supplies the low-voltage power needed to keep the system clock and BIOS settings active when the main battery is removed or depleted. The lithium cell arrives tested and ready to install on the motherboard.

Suits owners of the listed Acer models

Builders repairing other laptop brands or newer Acer chassis should look elsewhere because the connector and form factor are specific to the 4551 and 4315 series. This part does not replace a main laptop battery and cannot power the system during use.

Lithium coin cell for BIOS clock retention

The battery uses lithium chemistry to provide stable voltage for the real-time clock and CMOS memory. No other specifications such as voltage or capacity are supplied so compatibility must be confirmed against the original motherboard part before purchase.
