Dr. Battery 7FJ92 for Dell Vostro

This Dr. Battery 7FJ92 is a new lithium-ion replacement battery rated at 11.1V and 49Wh. It is built for owners of Dell Vostro 3400, 3500 or 3700 laptops who need to restore original run time. The pack uses professional-grade cells and includes short-circuit, overheat and overload protection.

Voltage and capacity match

The single specification that decides fit is the 11.1V / 4400mAh rating matching the original Dell part numbers listed. Your existing battery must show 11.1V and one of the compatible numbers such as 7FJ92, CYDWV, 04D3C, 312-0997 or 312-0998; a different voltage or capacity means this pack will not work. Buyers with other Dell models or different voltage requirements cannot use this unit.

One-year warranty included

The bundle adds a one-year manufacturer warranty covering defects in materials and workmanship. No extra cables, tools or software are supplied; the package contains only the battery itself. Users who need installation hardware or diagnostic utilities must source them separately.

Questions about this item

How long will the 49 Wh capacity keep a Dell Vostro 3400 running on a full charge?

The 49 Wh rating means the pack stores 49 watt-hours of energy; actual runtime depends on the laptop's power draw, screen brightness, and workload, but it matches the original Dell battery capacity for the Vostro 3400, 3500 and 3700 series.

What connection standard does the 11.1 V pack use to mate with the Vostro motherboard?

The battery uses Dell's proprietary multi-pin connector designed for the Vostro 3400, 3500 and 3700 chassis; it plugs directly into the motherboard without adapters or cables.

Will the 7FJ92 pack fit the internal battery bay of a Vostro 3700 without modification?

Yes, the pack is built to the same physical dimensions and screw-hole pattern as the original Dell 7FJ92, CYDWV, Y5XF9 and 04D3C batteries, so it drops into the Vostro 3700, 3500 or 3400 battery compartment and secures with the existing latches.
