Compatible CMOS Battery for HP G72-259WM

This lithium CMOS battery replaces the BIOS RTC cell on HP G72-259WM laptop motherboards. It maintains system time and firmware settings when the main power is disconnected. The unit is tested before shipping and arrives new.

Steady Low-Current Operation

The cell delivers a continuous microamp-level current to the real-time clock circuit rather than high bursts. Voltage remains stable over the operational lifespan expected of a lithium coin cell. This behaviour preserves BIOS configuration without interruption during long periods of mains disconnection.

Lithium Coin-Cell Interface Limits

The battery uses a standard two-pin connector keyed for the target motherboard header. Polarity and physical dimensions are fixed by the laptop design, so the part fits only the specified compatible models. No charging circuit is involved; the cell is primary lithium and non-rechargeable.

Questions about this item

How much power does the CMOS battery draw when the HP G72-259WM runs all day?

The lithium CMOS battery only powers the real-time clock when the laptop is off, so it draws negligible current during daily use.

What else must I already own to install this CMOS battery in an HP G72-259WM?

You need a small Phillips screwdriver to open the chassis and access the motherboard battery socket.

Will this CMOS battery work if I keep the original HP G72-259WM motherboard?

Yes, it is a direct replacement for the factory CMOS RTC cell on that motherboard.
