DELL 8K84Y 76 Wh 6-Cell 11.4 V Laptop Battery

SKU CH-8G1H-H43Y4

A 76 Wh, 6-cell lithium-ion laptop battery delivering 11.4 volts for compatible Dell systems

  • Battery typeLithium-Ion
  • 76 Wh capacity supports extended runtime between charges
  • 6-cell lithium-ion design balances energy density with reliability
  • 4 V output matches original Dell power specifications
  • Part number 8K84Y ensures direct compatibility with supported models
  • New condition delivers full rated performance from first use

Compatible Dell 76 Wh Battery

This 76 Wh lithium-ion battery replaces part number 08K84Y in supported Dell laptops. It delivers 11.4 V through a six-cell layout designed for direct fitment. The unit suits owners who need a factory-spec replacement for a depleted original pack.

Steady Capacity Over Full Discharge

The 76 Wh rating reflects usable energy across a complete cycle rather than a peak burst figure. Six cells share the load to maintain consistent voltage as the charge declines. This behaviour supports predictable run-time during long work sessions away from mains power.

Six-Cell Construction And Daily Use

A six-cell lithium-ion pack balances energy density with structural rigidity for repeated insertions. The 11.4 V output matches the system charging circuit without adaptation. Buyers who require a higher-capacity alternative or a different voltage platform should verify their model specifications before ordering.

Questions about this item

Does the 76 Wh 6-cell 11.4 V battery run hot or draw extra power during all-day use?

The 76 Wh lithium-ion pack is designed for normal operating temperatures; it does not consume AC power while the laptop runs on battery alone.

Must my laptop already have an 8K84Y or 08K84Y part number to use this battery?

Yes — the battery replaces Dell part numbers 8K84Y and 08K84Y, so the original laptop must accept one of those codes.

Will this 11.4 V pack work alongside my older Dell charger and internal charging circuit?

The 11.4 V output matches the original specification, so the existing charger and motherboard charging logic operate exactly as before.
