DBTLAP CMOS Battery for Lenovo IdeaPad B570

Compatible Lenovo IdeaPad B570 CMOS Battery

The DBTLAP CMOS battery is a direct replacement for the RTC BIOS cell used in Lenovo IdeaPad B570 laptops. It restores the system clock and BIOS settings when the original coin cell fails. This part is intended for laptop motherboards, not the main laptop battery pack. Buyers needing a main power battery for portable use should look elsewhere.

Lithium Coin Cell Chemistry

The battery uses a standard lithium chemistry to provide the low, steady voltage required for real-time clock and CMOS memory retention. It comfortably handles the minimal current draw of the BIOS chip for extended periods. The cell will eventually deplete after several years of continuous service, at which point the system clock will again lose time.

Low Power Passive Operation

As a passive component, the battery draws no measurable power from the system and generates no heat during normal operation. It operates silently with no moving parts or active cooling requirements. The unit is tested before shipping to verify voltage output and basic functionality. Installation simply requires placement into the motherboard holder.
