Replacement battery for Dell notebooks
The Battery Technology Inc. 5TF10-BTI is a 4 cell lithium-ion pack rated at 7.6V and 8000 mAh. It stores 64 Wh of energy and is finished in black. The unit is supplied new and matches the original form factor for compatible Dell models.
Who this suits and who should look elsewhere
Owners of supported Dell notebooks who need a direct replacement will find the correct voltage and connector. Buyers whose laptop requires a different cell count, voltage or physical layout cannot use this battery. It is not a universal power bank and will not charge other devices.
Fitting it into your build
Installation uses the existing battery bay and latch mechanism. No extra cables, adapters or tools are required beyond what the notebook provides. The 64 Wh capacity restores the original runtime without changing the system's weight balance or thermal profile.
