Drop-in replacement for Lenovo 3000 and V100 series

This Axiom 40Y8321-AX battery fits the Lenovo 3000 and V100 series notebooks. It uses a six-cell lithium-ion pack built to 100 % OEM compatibility. The unit arrives new and ready to install without extra tools.

Six-cell lithium-ion pack in the original form

The battery matches the factory footprint and connector layout so it seats securely in the existing bay. Lithium-ion chemistry delivers stable voltage through the discharge cycle and supports normal charge routines. No adapter cables or firmware updates are required.

Verify the exact Lenovo model before ordering

Confirm that your notebook is listed in the 3000 or V100 families because other Lenovo lines use different battery keys. Check the old pack for the 40Y8321 part number to be certain of the match. Buyers who need a higher-capacity pack or a different voltage should look elsewhere.

Questions about this item

Does the 40Y8321-AX use the same lithium-ion interface as the original Lenovo 3000 V100 battery?

Yes, it is a 6-cell lithium-ion pack built to match the original Lenovo 3000 V100 electrical interface and form factor.

Will this 6-cell pack fit the battery bay of a Lenovo 3000 V100 without modification?

The battery is shaped to the original Lenovo 3000 V100 bay dimensions, so it seats directly without adapters or case changes.

What is the correct way to install the 40Y8321-AX, and what step do people often miss?

Slide the pack into the bay until the latch clicks, then charge it fully before first use; skipping the initial full charge is the common mistake.
