What this battery replaces

The NShi 51Wh 93FTF lithium-ion pack replaces the original Dell 93FTF, D4CMT, 4YFVG, 83XPC and 083XPC batteries. It matches the 11.4 V, three-cell, 51 Wh specification used in Latitude 5280, 5480, 5580, 5490, 5590, 5288, 5290, 5488, 5491, 5495 and Precision 3520 or 3530 models. Choose this unit when the existing pack no longer holds a useful charge and the laptop requires the lower-capacity 51 Wh variant rather than the 42 Wh, 68 Wh or 92 Wh alternatives.

When the upgrade makes sense

Swapping to this 51 Wh replacement is worthwhile when the factory battery has degraded below daily needs and the chassis is designed for the slimmer three-cell form factor measuring 7.7 by 4.1 by 0.2 inches. The pack includes short-circuit, overheat and overload protection circuits. It restores original runtime without the bulk or weight of the higher-capacity options that some configurations cannot accept.

Who should buy and who should not

This battery suits owners of the listed Dell Latitude and Precision models whose original part number is 93FTF or one of the compatible codes. Buyers whose laptop shipped with the 42 Wh, 68 Wh or 92 Wh packs should select the matching capacity instead, as the 51 Wh unit will not provide the runtime those systems were designed for. Anyone needing a different voltage, cell count or physical size should look at the correct variant for their specific model.

Questions about this item

What are the physical dimensions of the 93FTF battery for the Dell Latitude 5480?

The pack measures 7.7 by 4.1 by 0.2 inches and uses a 3‑cell lithium‑ion layout, so it fits the same bay as the original 51Wh unit.

Which step do people often miss when installing this 11.4V replacement in a Precision 3520?

After sliding the battery into the compartment, the locking latch must be pressed until it clicks; otherwise the pack can sit loose and fail to charge.

When should the 4500mAh cell be swapped out in a Latitude 5590?

Replace it once run time drops noticeably below the original 51Wh rating or the pack no longer holds a full charge after a normal charging cycle.
