FOCUSTEC 5200mAh 6-cell replacement

This new lithium-ion battery replaces the original pack in Dell Latitude D620, D630, D630c and D631 notebooks as well as Precision M2300 mobile workstations. It delivers 5200mAh capacity across six cells and is built to match the factory form factor of 185.10 x 66.45 x 19.10 mm weighing 313.0 g. The unit carries CE, UL and RoHS certifications for safe operation.

Check voltage and part number first

Your existing battery must show a nominal voltage of 10.8 V, 11.1 V, 14.4 V or 14.8 V; all four are supported by this replacement. Verify that the part number on your current pack matches 312-0393 or YD623 before ordering. The battery is not suitable for laptops outside the listed Latitude and Precision models or for systems requiring a different cell count or voltage range.

Thermals, noise and power draw

As a passive chemical cell the battery generates no fan noise and adds no active cooling load to the chassis. Normal discharge follows the laptop's own power management without extra heat beyond what the original pack produced. The 5200mAh rating supports typical mobile workloads at the same voltage levels the system expects.

What runtime improvement can I expect from the 5200 mAh capacity on a Latitude D630?
