Rome Tech CR2032 CMOS Battery 3-Pin Cable 5-Pack for Dell Latitude E5400 E5410 E6400 E6410 E6500 E6510

SKU CH-SZRM-FNKHD

Five CR2032 lithium CMOS batteries with 3-pin cables replace the BIOS backup cell in compatible Dell Latitude models

  • Battery TypeLithium Polymer
  • Ready for Dell Latitude E5400 E5410 E6400 E6410 E6500 E6510
  • Lithium polymer cell holds charge up to 10 years in storage
  • 3-pin cable installs in about 10 minutes without soldering
  • Five-pack keeps spares on hand for multiple systems
  • Zero-mercury CR2032 design fits tight chassis spaces

Replacement BIOS Battery

This five-pack of CR2032 lithium-polymer cells is built to replace the CMOS battery in Dell Latitude E5400, E5410, E6400, E6400 ATG, E6410, E6500 and E6510 notebooks. Each unit arrives with a three-pin wire cable and matching connector so no soldering or modifications are required during installation. The pack suits IT teams and owners who maintain multiple machines of these models.

Long-Term Charge Retention

The lithium-polymer chemistry holds usable voltage for up to 10 years in storage, keeping spares reliable until they are needed. In service the cell maintains the real-time clock and BIOS settings continuously without the voltage sag that can appear with older chemistries under sustained low-current draw. This stability reduces the chance of configuration loss during extended periods when the main battery is removed.

Low-Power Thermal Profile

Because the cell operates at microampere levels it generates no measurable heat and requires no active cooling in the laptop chassis. The compact 2032 form factor fits the existing battery compartment without stressing surrounding components or cables. Zero-mercury construction meets environmental safety standards while delivering consistent 3 V output throughout its service life.

Questions about this item

Does the CR2032 CMOS battery generate noticeable heat or noise during continuous laptop operation?

The lithium coin cell operates passively with no moving parts, so it produces no audible noise and negligible heat while maintaining the system clock and BIOS settings.

What connector must the laptop motherboard already have for this 3-pin cable to plug in directly?

The cable uses a 3-pin, 3-wire connector that matches the original Dell Latitude E5400, E5410, E6400, E6400 ATG, E6410, E6500 and E6510 motherboard header.

Will this replacement battery work alongside the original main battery in an older Latitude E6400 without conflicts?

Yes, the CMOS cell is independent of the main power pack; it only supplies 3 V to the real-time clock and CMOS memory, so both batteries coexist without interference.
