DELL CR2032 CMOS BIOS 3V Lithium Coin Battery 2HH65

Genuine Dell CR2032 CMOS battery for Inspiron

This is a brand new genuine Dell OEM CR2032 coin-cell battery rated at 3V for CMOS and BIOS memory retention. It carries Dell part numbers 2HH65 and 2M41K and fits a wide range of Inspiron, Latitude, G-Series, XPS, Vostro, Studio and Precision T1650 models listed by the manufacturer. Replacing the cell restores system time and BIOS settings after the original battery is exhausted.

Long-term charge retention for continuous BIOS power

The lithium chemistry provides a stable 3V supply that maintains CMOS memory and the real-time clock for years under typical standby loads. Unlike short bursts of high current, the cell is designed for very low continuous drain, so voltage remains steady throughout its service life. A fresh battery prevents the clock-reset and configuration-loss symptoms that appear when the original cell finally depletes.

Verify the exact model number before ordering

Check the service tag or the existing battery label to confirm that your laptop appears in the manufacturer compatibility list. The part is not universal across all Dell systems, so matching the specific Inspiron, Latitude, G-Series, XPS, Vostro, Studio or Precision T1650 model is essential. No tools beyond a small screwdriver are usually required, but access difficulty varies by chassis design.
