CMOS Battery for Toshiba Satellite A205-S4577

This lithium CMOS battery replaces the BIOS RTC cell on the motherboard of the Toshiba Satellite A205-S4577 laptop. It is a new replacement part tested before shipping. The package includes one battery unit. It restores system clock and BIOS settings retention when the original cell fails.

For Satellite A205-S4577 owners

This part suits users whose laptop loses the date, time or BIOS configuration after a shutdown. It is not a main laptop battery and will not power the system for portable use. Buyers needing a primary power source for mobile operation should look elsewhere. It also does not fit other laptop models or motherboard types.

Lithium coin cell for BIOS RTC function

The battery uses lithium chemistry to maintain the real-time clock and CMOS memory on the specific motherboard. No other battery type or voltage is provided. Compatibility is limited to the Toshiba Satellite A205-S4577 model. Installation requires opening the laptop chassis to access the motherboard socket.

Questions about this item

Does the lithium cell run hot or drain quickly when the laptop stays on for long periods?

The CMOS battery only powers the real-time clock and BIOS memory when the main power is off, so it produces no noticeable heat and draws virtually no current during daily use.

Must I already have the original cable and connector attached to the motherboard for this battery to fit?

Yes, the replacement cell uses the same two-pin connector as the factory unit on the Satellite A205-S4577, so the existing motherboard header is all that is required.

Will this CMOS battery keep the clock and BIOS settings on an older Satellite A205-S4577 that still has its original motherboard?

It is built as a direct replacement for that model, so the original motherboard will recognise it and retain date, time and CMOS configuration exactly as before.
