Compatible Dell Inspiron 1564 CMOS Battery

This replacement CMOS RTC battery is designed for the Dell Inspiron 1564 motherboard. It restores BIOS settings and real-time clock function when the original cell fails. The lithium cell arrives new and tested before shipping. It is not a main laptop power battery.

Sustained Load Behaviour

The lithium chemistry provides stable voltage for continuous CMOS memory retention over long periods. It maintains BIOS configuration without interruption during extended system downtime. The cell delivers consistent low-current performance throughout its service life. No capacity fade occurs under normal motherboard load.

Thermals Noise and Power Draw

The battery operates passively with zero acoustic output and no heat generation. It draws only microampere current from the motherboard RTC circuit. Power consumption is negligible and does not affect system thermals. The sealed lithium cell requires no active cooling or maintenance.

Questions about this item

How much power does the CMOS battery draw when the Dell Inspiron 1564 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 inside the Dell Inspiron 1564 for this battery to work?

You need the original motherboard header and clip that accept a standard coin-cell CMOS battery.

Will this CMOS battery fit older Dell laptops that I might still use?

It is listed as compatible for the Inspiron 1564; fitment on other models depends on their motherboard battery socket and voltage requirement.
