Compatible CMOS Battery for Dell Inspiron 15-5547

This replacement CMOS battery is designed for the Dell Inspiron 15-5547 laptop motherboard. It maintains BIOS settings and the real-time clock when the main power is disconnected. The unit uses lithium chemistry and is supplied as a single tested component. It is not a main laptop battery.

For owners replacing a failed BIOS battery

This part suits anyone whose Dell Inspiron 15-5547 shows CMOS checksum errors, date and time resets, or BIOS settings lost after shutdown. It will not help users who need a main power battery to run the laptop unplugged. Buyers looking for a primary rechargeable battery pack should look elsewhere.

Holds BIOS data continuously under low load

The lithium cell delivers a steady micro-current to the motherboard RTC circuit over years of operation. It is not subject to high-drain cycles, so capacity fade is gradual and predictable. The battery is tested before shipping to verify it meets the voltage requirement for reliable CMOS retention.

Questions about this item

Does this CMOS battery fit the Dell Inspiron 15-5547 motherboard directly?

Yes, the battery is specified as compatible for the Dell Inspiron 15-5547 and is tested before shipping to ensure it fits the motherboard CMOS socket.

Will the lithium CMOS battery keep BIOS settings if I keep my existing laptop battery?

The CMOS battery powers the real-time clock and BIOS memory independently, so it maintains settings even when the main laptop battery is removed or depleted.

How can I confirm the new CMOS battery is working after I install it?

After installation, boot the laptop, enter BIOS setup and verify the date and time are correct; they should hold after a full power-off and restart.
