Replacement battery for HP 6720s and 6820s

This Axiom GJ655AA-AX battery is a 100% OEM-compatible lithium-ion power source built for HP 6720s and 6820s notebooks. It uses proprietary dimensions and high-quality cells to deliver reliable runtime when away from mains power. The pack is rechargeable and designed as a direct swap for the original unit.

Who this suits and who should look elsewhere

It suits owners of the listed HP models who need a new lithium-ion pack to restore mobile operation. Buyers with other HP series or different manufacturers should look elsewhere because the proprietary form factor and connector only match the 6720s and 6820s.

Proprietary lithium-ion form factor

The battery uses a proprietary size and lithium-ion chemistry that physically and electrically matches the original HP design for the 6720s and 6820s. This single specification decides whether the part will fit and function in the target notebook.

Questions about this item

Which Axiom GJ655AA-AX battery fits my HP 6720s or 6820s notebook?

The GJ655AA-AX is built as a direct replacement for HP 6720s and 6820s models, so the single listed version covers both series without additional capacity options.

How long will this lithium-ion pack run my laptop on a full charge?

Runtime depends on the notebook's power draw, screen brightness and workload; the battery stores the same energy as the original pack and will deliver comparable unplugged time.

What connector does the GJ655AA-AX use and will it charge at the standard rate?

It uses the proprietary HP connector fitted to the 6720s and 6820s, and the lithium-ion chemistry accepts the notebook's normal charging current without limitation.
