Compatible HP Mini-Note Replacement

The Axiom KU528AA-AX lithium-ion battery is built for the HP 2133 and 2140 Mini-Note PCs. It matches the OEM part numbers KU528AA and 484783-001 for direct fit. RoHS certification confirms environmentally responsible materials. This new unit restores untethered runtime for mobile professionals.

Thermals and Power Draw

Lithium-ion chemistry delivers stable voltage without memory effect during daily charge cycles. The proprietary pack fits the original bay, so airflow and thermal paths remain unchanged. At 14.50 oz it adds negligible weight to the ultraportable chassis. Rechargeable design supports repeated discharge and recharge without special conditioning.

Build Integration

The battery slots into the existing compartment using the factory latch mechanism. No tools, adapters or cable routing are required for installation. RoHS compliance aligns with corporate procurement policies for hazardous-substance limits. It serves owners of the listed Mini-Note models who need a fresh power source; it is not suited for other HP families or larger notebooks.

Questions about this item

How do I install the Axiom KU528AA-AX battery in my HP 2133 Mini-Note, and what step do people often miss?

Slide the pack into the bay until the latch clicks, then lock the latch; the step often missed is moving the latch to the locked position after the click.

What maintenance will the Axiom KU528AA-AX lithium-ion pack need, and when should I replace it?

Calibrate monthly by running the notebook on battery until it sleeps, then charge to full; replace the pack when runtime no longer meets your needs.

What limit appears first during sustained use of the Axiom KU528AA-AX in an HP 2140?

The 14.50 oz pack will hit its thermal limit before the lithium-ion chemistry reaches its voltage floor, so the system throttles to protect the cells.
