Compatible replacement for HP Probook 6465b

This CMOS battery is designed specifically for the HP Probook 6465b laptop motherboard. It replaces a faulty or depleted BIOS RTC cell to restore system time and firmware settings. The part is a direct-fit lithium unit supplied as a single replacement component. It is intended for owners of this exact model needing a reliable board-level repair.

Sustained real-time clock stability

Lithium chemistry delivers a steady low current over years rather than a brief burst of power. The cell maintains BIOS configuration and accurate clock data during long periods when the main battery is removed or the machine is unplugged. Each unit is tested before shipping to verify correct voltage and leak-free operation. Consistent output prevents checksum errors and boot delays caused by a weakening cell.

Snap-in mounting with pre-wired connector

The battery arrives with its original connector and lead length, allowing a direct plug into the motherboard header without soldering. Compact dimensions match the factory retainer clip for a secure, rattle-free fit inside the chassis. Sturdy shrink-wrap insulation protects the contacts during handling and installation. No additional cables, brackets or adapters are required for day-to-day service.

Questions about this item

How much power does the CMOS battery draw while the ProBook 6465b runs all day?

The lithium CMOS battery only supplies a tiny standby current to keep the real-time clock and BIOS settings alive; it does not power the laptop during normal operation.

What else must I already have to install this CMOS battery in the ProBook 6465b?

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

Will this CMOS battery work alongside the original main battery in my ProBook 6465b?

Yes, the CMOS cell is a separate component on the motherboard and operates independently of the main laptop battery.
