Ready replacement battery

The Total Micro Technologies 7WNW1TM is a 3-cell 51Whr 11.4V laptop battery built to meet or exceed OEM specifications. It restores mobile power for users whose original pack no longer holds a useful charge.

Fits the original bay

The pack slides into the factory battery compartment without adapters or cable changes. It draws charging current from the existing AC adapter and requires no BIOS update or driver install to operate.

Replaces a worn OEM cell

Swapping in this unit ends the cycle of tethered use and sudden shutdowns caused by an aged battery. The upgrade is worthwhile when the original pack delivers only a fraction of its rated runtime.

Questions about this item

How long does the 51Whr capacity last under continuous load?

The 51Whr rating indicates total energy storage; actual run time varies with the laptop's power draw, screen brightness and workload.

Does the 11.4V battery run hot or make noise during all-day use?

Lithium-ion cells operate silently; warmth is normal under load but excessive heat suggests a firmware or hardware issue in the host laptop.

Which laptop models accept the 7WNW1TM part number?

The 7WNW1TM is a direct replacement for specific Dell Latitude and Precision systems; verify the original battery part number before purchasing.
