Compatible CMOS Battery for HP Pavilion g7-1156nr

This lithium CMOS battery is designed specifically for the HP Pavilion g7-1156nr laptop motherboard. It replaces the original RTC battery that maintains BIOS settings and the system clock when the main power is disconnected. The unit is intended for technicians or owners repairing a laptop that loses time or configuration data. It is not a main laptop power battery and will not run the system.

Lithium Coin Cell Interface Limits

The battery uses a standard lithium coin cell chemistry to provide low current over a long period. It cannot supply the high current needed for system operation or charging other components. The interface is a simple two-wire connection to the motherboard header, so no data communication or smart battery features are supported. Polarity must be observed during installation to avoid damage to the CMOS circuitry.

Tested Unit with Direct Connector Mount

Each battery is tested before shipping to verify voltage and basic function. The connector allows direct plug-in mounting onto the motherboard header without soldering. This simplifies replacement and reduces the risk of heat damage to the board. The compact lithium cell fits the original battery compartment, restoring reliable timekeeping and BIOS retention for daily use.
