Replacement battery for Dell Precision mobile

This 9-cell lithium-polymer pack delivers 7800mAh at 11.1V and is built as a direct replacement for Dell Precision M4600 M4700 M4800 M6600 M6700 M6800 systems. It matches the original form factor and connector so installation requires no adapters or modifications. The unit is new and rated for up to 500 recharge cycles over its service life.

Voltage and capacity determine compatibility

The battery operates at 11.1V with a 7800mAh capacity yielding 89Wh of energy storage. These electrical ratings must match the original specification exactly; a different voltage or cell count will prevent the laptop from recognising or charging the pack. Verify the part number on your existing battery against the supported list before purchase.

Protection circuits add operational safety

Integrated overcurrent, overcharge, overdischarge, over-temperature and short-circuit safeguards protect both the battery cells and the host laptop during charging and heavy load conditions. The circuitry is calibrated to meet OEM standards and supports fast charging without manual configuration. No additional software or drivers are required for the protection features to function.

Questions about this item

What does the 7800 mAh rating mean for daily runtime on a Precision M6800?

The 7800 mAh capacity stores 89 Wh of energy, giving several hours of typical office work on a full charge; actual runtime varies with screen brightness, workload and battery age.

Does the 11.1 V output match the original Dell battery connector and charging circuit?

Yes, the 11.1 V lithium-polymer pack uses the same connector and pin-out as Dell part numbers such as 0TN1K5 and PG6RC, so the laptop’s charging controller recognises it without modification.

Will the 9-cell pack fit flush in the Precision M4700 battery bay?

The 9-cell design follows the original Dell form factor for the M4600, M4700, M4800, M6600, M6700 and M6800 series, so it seats securely in the existing bay without adapters.
