3-Cell 45Whr Replacement Battery

This Total Micro Technologies battery replaces a depleted Lenovo laptop pack with a 3-cell 45Whr unit. It restores mobile run time for supported models and is sold new. Compatibility depends on the specific Lenovo part number used in the original system. Verify the part number before ordering.

When an old pack no longer holds charge

Swap this battery in when the original Lenovo pack drops below usable capacity or fails to charge. The upgrade is worth it when the laptop chassis is otherwise sound and the original part number matches this 3-cell 45Whr specification. It returns the device to portable operation without a full system replacement.

Fits inside the existing battery bay

The pack installs directly into the laptop's original battery compartment using the factory connector and latch mechanism. No extra cables, adapters or tools are required beyond what the chassis provides. It frees the user from permanent wall-outlet dependence and restores true mobile use for the supported Lenovo model.

Questions about this item

What physical space does the 3-cell 45Whr battery occupy inside a Lenovo laptop?

The pack uses a standard 3-cell form factor designed to fit the original battery bay in compatible Lenovo models.

How is the battery installed and which step do people often miss?

Power off the laptop, remove the bottom cover, disconnect the old pack, connect the new 3-cell unit, then secure the cover before turning the system on.

What maintenance or replacement will the 45Whr battery need over time?

Lithium-ion cells lose capacity with each charge cycle; plan to replace the pack when runtime no longer meets your needs.
