DBTLAP CMOS RTC Battery for Toshiba Satellite L655-S5160

SKU CH-PRDJ-8XHFH

Lithium CMOS battery keeps the real-time clock running on Satellite L655-S5160 motherboards

  • Battery TypeLithium
  • Lithium chemistry maintains reliable BIOS timekeeping
  • Direct replacement for Satellite L655-S5160 motherboards
  • Pre-tested unit ensures immediate CMOS function
  • Single battery package simplifies installation
  • Restores system clock and BIOS settings retention

Compatible CMOS RTC Battery

This lithium CMOS RTC battery is designed for the Toshiba Satellite L655-S5160 motherboard. It replaces a faulty or depleted BIOS battery to restore system time and hardware settings. The unit is new and tested before shipping. Buyers needing a main laptop power battery will not find it here.

Low Power Thermal Profile

The battery draws only microampere current to maintain the real-time clock. It generates no measurable heat and produces no audible noise during normal operation. Power consumption is negligible and does not affect the laptop’s main battery life. No active cooling or thermal management is required.

Direct Motherboard Mounting

The package includes one CMOS battery with a connector suited for the Satellite L655-S5160 board. Installation involves plugging the lead into the motherboard header and securing the cell in its holder. No additional cables, adapters or tools are supplied. Builders without access to the motherboard compartment cannot complete the replacement.

Questions about this item

How do I install this CMOS battery in the Satellite L655-S5160 and which step is most often missed?

Open the chassis, locate the coin-cell holder on the motherboard, remove the old cell noting its orientation, insert the new lithium cell with the same polarity, then reassemble; the step most often missed is verifying the positive side faces the correct contact before closing the case.

What maintenance or replacement will this CMOS battery need later?

The lithium coin cell typically lasts several years; when the system clock starts losing time or BIOS settings reset after power loss, replace it with an identical CR-series coin cell.

What limit appears first under sustained use of this CMOS battery?

The cell’s finite capacity is the first limit; continuous drain from the real-time clock eventually depletes the charge, causing the clock to drift and BIOS settings to clear until the battery is swapped.
