Replacement for HP HSTNN-DB1B Series

This 6-cell lithium-ion battery replaces the original HP HSTNN-DB1B, HSTNN-I85C and related part numbers. It fits HP laptops designed for an 11.1V power source and restores mobile operation when the factory pack no longer holds charge.

Upgrade from a depleted or lower-capacity pack

The jump is worth it when the original battery drains quickly, cannot reach full charge or has swollen. A fresh 5200mAh cell restores the runtime the laptop delivered when new and removes the need to stay tethered to an outlet.

Fits the existing battery bay without modification

The pack uses the same form factor and connector as the factory unit, so no chassis changes or adapter cables are required. It frees the user from carrying a bulky power brick during meetings or travel and supports CE and RoHS certified safety standards.

Questions about this item

What voltage and cell count does the 11.1V 5200mAh battery require for a proper fit?

The battery is built to 11.1V with 6 premium lithium-ion cells, matching the original HP specification for a direct fit.

How do I install the HSTNN-DB1B battery and which step is most often missed?

Power off the laptop, unplug the AC adapter, slide the release latch, swap the old pack for the new one, then press firmly until the latch clicks — the click is the step people skip.

When will the 5200mAh 6-cell pack need replacement and what is covered?
