The unit uses lithium-ion cells rated at 11.1V and 6600mAh for 73.26Wh of energy. A 6.6Ah rating supports typical mobile workloads on the listed Latitude models. The black casing matches the original aesthetic. Buyers who need a higher watt-hour rating or a different voltage will not find it here.

Installation notes

The battery measures 208.00 x 79.28 x 21.20 mm and slides into the standard battery bay on the compatible chassis. No tools are required beyond the laptop's own release latch. Alignment tabs prevent incorrect insertion. Installers who force the connector or ignore the latch orientation risk bent pins or a loose fit.

Questions about this item

How often will the 6.6 Ah lithium-ion cells need replacing?

The 6.6 Ah lithium-ion pack is rated for hundreds of charge cycles; typical service life is several years before capacity drops below usable levels.

What limits runtime first when the 73.26 Wh battery runs continuously?

The 6600 mAh capacity at 11.1 V defines the energy ceiling; sustained heavy loads will drain the 73.26 Wh store before any other factor intervenes.

Does the 208 mm by 79.28 mm black pack get hot or loud during all-day use?

The sealed 21.20 mm thick lithium-ion unit has no moving parts, so it runs silently and stays near ambient temperature under normal loads.
