CMOS battery for Satellite M305D-S4829

This DBTLAP lithium CMOS battery fits the Toshiba Satellite M305D-S4829 motherboard. It maintains the real-time clock and BIOS settings when the main power is off. The unit is new and tested before shipping. It replaces a faulty or depleted RTC cell.

Steady voltage for BIOS retention

Under continuous load the cell delivers a stable voltage to keep the system clock and firmware configuration intact. It is designed for long-term, low-current operation rather than high-drain bursts. The lithium chemistry supports consistent performance over the battery's service life. No capacity fade is expected during normal motherboard use.

Direct replacement for original RTC cell

This part upgrades a dead or leaking factory CMOS battery on the Satellite M305D-S4829. The jump is worth it when the laptop loses time, date or BIOS settings after shutdown. It is not for users who need a main laptop power pack or a higher-capacity coin cell than the original specification.

Questions about this item

Does the CMOS battery draw noticeable power or generate heat while the laptop runs all day?

The lithium CMOS battery only powers the real-time clock when the laptop is off, so it adds no measurable heat or power draw during daily use.

What must I already have in the laptop for this battery to work?

You need a motherboard with a standard two-pin CMOS header that matches the original battery for the Satellite M305D-S4829.

Will this replacement CMOS battery keep the clock and BIOS settings on an older Satellite motherboard?

Yes, it is a direct lithium RTC replacement for the Satellite M305D-S4829 and restores date, time and BIOS settings on that board.
