Direct replacement battery
The BTI 8FCTC-BTI is a 3 Cell Lithium-Ion laptop battery built for compatible Dell notebooks. It delivers 4912 mAh at 11.4 V for a total of 56 Wh of energy. The black pack fits the original bay without modification. Buyers needing a different voltage or form factor should look elsewhere.
Restores original runtime
This unit replaces a depleted or aging factory battery that no longer holds a useful charge. The upgrade is worthwhile when the notebook shuts down unexpectedly or tethered use has become mandatory. It does not increase capacity beyond the original 56 Wh specification. Systems requiring higher watt-hour ratings will not benefit.
Drop-in fit for supported models
The battery slots into the existing compartment and connects to the stock charging circuit. No adapter cables, firmware updates or BIOS changes are required. It frees the user from permanent mains dependency while preserving the notebook’s original profile. Compatibility must be verified against the specific Dell model before purchase.

Questions about this item
What Dell notebook models accept the 8FCTC-BTI 3-cell lithium-ion pack?
