Replacement Battery for Dell Latitude and Precision

This 5200mAh 11.1V lithium-ion pack replaces the original battery in Dell Latitude D531, D531N, D820 and D830 models as well as Precision M4300, M65 and M65 Mobile systems. It matches part numbers such as 0MM160, 312-0393 and CF623 so technicians can swap the pack without guessing compatibility. The six-cell design restores mobile operation for aging workstations that otherwise stay tethered to an outlet.

Thermal Behaviour and Power Efficiency

The pack uses standard Li-ion chemistry with built-in circuit protection that limits over-current and short-circuit events during normal charging and discharge. Supplier data notes fast charging and low power consumption, meaning the battery accepts charge quickly and does not add noticeable heat to the laptop chassis under typical office workloads. Rated for up to 500 recharge cycles, it maintains stable voltage delivery throughout its service life.

Upgrading from a Depleted Original Pack

This unit is intended for owners whose factory battery no longer holds a useful charge or has swollen, and who want a direct drop-in replacement with the same voltage and capacity. It does not increase runtime beyond the original 5200mAh specification, so users needing longer unplugged sessions should look for a higher-capacity alternative if one exists for their chassis. The jump is worth it when the old pack fails completely or triggers safety warnings.

Questions about this item

How do I install the 6-cell 11.1V battery in my Dell Latitude D830, and what step is often missed?

Power off the laptop, disconnect the AC adapter, slide the release latch, insert the 5200mAh pack until it clicks, then lock the latch; the step often missed is fully seating the pack before locking so the connector aligns.

What maintenance or replacement will the Li-ion 5200mAh battery need later?

Expect up to 500 recharge cycles over its life; once runtime drops noticeably, replace the pack — no user-serviceable cells or calibration routine is required.

What limit appears first during sustained use of this 11.1V 6-cell replacement?

The 500-cycle rating is the first hard limit; after that capacity fades and the pack should be swapped for a new unit.
