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?

The 8FCTC-BTI is built as a direct replacement for compatible Dell notebooks that originally shipped with an 11.4 V 56 Wh battery; match the original part number before ordering.

How is the 8FCTC-BTI installed and what step is commonly missed?

Power off the notebook, unplug the AC adapter, release the battery latch, swap the old pack for the 8FCTC-BTI, then press until the latch clicks — many users forget to fully seat the latch.

When will the 4912 mAh 3-cell pack need replacement?

Capacity fades with each charge cycle; plan to replace the pack when run time falls well below the original 56 Wh rating or the notebook shuts down unexpectedly.
