What this battery does

This DBTLAP CMOS battery replaces the RTC BIOS cell on a Lenovo IdeaPad Z570 motherboard. It keeps the system clock and firmware settings alive when the main power is off. The lithium cell is tested before shipping and arrives new.

Capacity and limits

The lithium chemistry provides the steady low current a CMOS circuit needs for years of continuous operation. It will not power the laptop itself and cannot substitute a main battery pack. When the cell finally exhausts, the clock will drift and BIOS settings may reset.

Thermals noise and power

The battery produces no heat and makes no sound during normal use. It draws only microamps from the motherboard, so it has no measurable effect on system power consumption or temperatures.
