A new lithium CMOS battery that keeps the Dell Latitude E5530 system clock and BIOS settings running
This replacement CMOS battery restores BIOS clock and configuration retention on a Dell Latitude 5530 motherboard. It suits technicians or owners repairing a laptop that loses time or settings after shutdown. The lithium cell is tested before shipping to confirm reliable operation.
The unit arrives as a complete assembly including the battery, wiring and motherboard connector for direct installation. No soldering is required, so replacement is straightforward during a motherboard service. Build quality targets dependable contact retention through repeated thermal cycles inside the chassis.
This component powers the RTC and CMOS memory; it does not supply main system power or charge the primary laptop battery. It addresses symptoms such as date reset, BIOS checksum errors or boot failure caused by a depleted coin cell. It will not resolve power-on faults unrelated to the CMOS circuit.

The battery uses a standard lithium chemistry cell designed to maintain BIOS settings and the real-time clock on the motherboard.
It fits the standard CMOS battery socket on the motherboard; no extra mounting hardware or adapter brackets are required.
Disconnect main power, open the chassis, unplug the old cell from the motherboard header, plug in the new one, then reassemble; the step often missed is removing all power sources before starting.
