CMOS Battery for Satellite U305-S7446

This DBTLAP lithium CMOS battery is a direct replacement for the real-time clock cell on Toshiba Satellite U305-S7446 motherboards. It restores BIOS settings retention and system time when the original cell is exhausted. The unit is new and tested before shipping. It is not a main laptop power battery.

Fits Motherboard RTC Socket

The battery plugs into the standard CMOS header on the notebook mainboard, requiring no soldering or additional cabling. Installation frees the system from losing date, time and firmware configuration during power-off periods. Buyers who need a primary rechargeable pack for portable operation will not find that function here.

Maintains Settings Under Continuous Load

The lithium cell delivers the steady micro-current draw needed to keep the RTC circuit alive for years of uninterrupted service. It sustains voltage stability during long storage intervals without mains power. The part is not designed for high-drain or cyclic discharge applications.

  • Direct replacement for Satellite U305-S7446
  • Lithium chemistry provides stable CMOS power
