The part arrives new and tested, ready for direct installation on the system board.

Target User

The battery suits owners of the Inspiron 5423 who see incorrect system time, lost BIOS configuration or CMOS checksum warnings at boot. It is not for users looking for a main laptop battery to power the portable device, nor for anyone needing a rechargeable pack or a different form factor for another laptop model.

Deciding Specification

The critical detail is the lithium coin-cell chemistry matched to the Inspiron 5423 socket. Only this exact replacement restores reliable RTC operation and prevents the configuration losses that signal a depleted cell.

Questions about this item

How long does the CMOS battery last before the system clock starts drifting?

The lithium cell typically holds charge for several years under normal motherboard load before the RTC begins to drift.

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

No, a CMOS battery is a passive component; it produces no audible noise and negligible heat while maintaining the real-time clock.

What connector does the battery use to attach to the Inspiron 5423 motherboard?

It uses the standard two-pin JST-style connector found on the Dell Inspiron 5423 motherboard for the CMOS RTC battery.
