Direct replacement for HP Compaq Presario notebooks

This Rome Tech CMOS battery replaces the original CR2032 cell in HP Compaq Presario CQ50, CQ60, CQ70, G50, G60, G62, G70, V2000, V3000, V3100, V3200, V3300, V3400, V3500 and V4000 series laptops. It also fits IBM Lenovo ThinkPad R30, R31 and R32 models. The two-wire connector with three pins matches the factory layout so no soldering is required.

Passive component with no active cooling

As a lithium coin cell the battery generates no heat, produces no noise and draws no measurable power during normal operation. It simply maintains the real-time clock and BIOS settings when the main system is off. The zero-mercury chemistry is rated to hold its charge for up to 10 years in storage.

Pre-wired connector and protective packaging

The unit ships with the correct two-wire cable and three-pin plug already attached, removing the need for adapter cables or pin rearrangement. An identification label lets you verify the part before installation. Protective packaging prevents damage during handling and the whole swap typically takes about 10 minutes.

Questions about this item

How do I install the 2-wire CMOS battery and which step is most often missed?

Unplug the old 2-wire connector, snap in the new CR2032 unit, and route the cable so the 3-pin plug seats fully — the step most often missed is pushing the connector until it clicks.

What maintenance or replacement will this CR2032 CMOS battery need later?

The lithium coin cell holds charge for up to 10 years in storage; after that period, or when the system clock drifts, replace the entire 2-wire module.

What limit appears first under sustained use of this CMOS battery?

The 3 V CR2032 cell eventually exhausts its charge, causing BIOS settings and the real-time clock to reset — that is the first limit you will encounter.
