ProBook 6445 and 6545 replacement battery

The Axiom AT908AA-AX is a new lithium-ion battery built for HP ProBook 6445 and 6545 notebooks. It matches the OEM AT908AA part number and fits the listed ProBook models without modification. The pack is rechargeable and meets RoHS environmental requirements for safer disposal.

Sustained discharge on lithium-ion chemistry

Lithium-ion cells deliver steady voltage across the discharge curve rather than a sharp drop near the end of charge. This behaviour keeps the notebook running predictably during long meetings or travel days when a power outlet is unavailable. The 14.50 oz weight reflects the cell density required for that consistent output.

Proprietary form factor limits interchangeability

The battery uses a proprietary size and connector keyed to the ProBook 6445 and 6545 chassis, so it cannot be swapped with packs from other HP families such as the 6440, 6450, 6540, 6550 or 8440 series. Users needing power for those models must source the correct dedicated pack.

Questions about this item

Does the lithium-ion chemistry in the AT908AA-AX generate noticeable heat during extended unplugged use?

Lithium-ion cells warm slightly under load but the pack is designed to stay within safe thermal limits for all-day mobile work.

Must my HP ProBook already have a proprietary battery bay that matches the AT908AA form factor?

Yes — the pack fits the proprietary bay used on ProBook 6445b, 6545b and the other listed models.

Will the 14.50 oz weight of this replacement change the balance of an older EliteBook 8440p I still use?

The mass matches the original OEM specification so the chassis balance remains unchanged.
